Description

Technical Field

[0001] This application relates to the field of power supply technology, and in particular to a computing device and a power converter. Background Technology

[0002] As the number of servers deployed in data centers gradually increases, a data center can accommodate 9000 PCS (Pieces) of servers. Each server includes a power converter and multiple loads. The power converter can be electrically connected between the power grid and the multiple loads, converting AC power received from the power grid into DC power and transmitting it to the multiple loads to supply power.

[0003] However, in related technologies, the output voltage of power converters can experience voltage dips, causing partial load power loss. It's important to note that these voltage dips refer to a sudden drop in the output voltage of the power converter, followed by a subsequent increase. Summary of the Invention

[0004] The purpose of embodiments of this application is to provide a computing device and a power converter for improving the phenomenon of load power failure.

[0005] To achieve the above objectives, embodiments of this application provide the following technical solutions:

[0006] On one hand, a computing device is provided. The computing device includes a first power converter, a second power converter, and a plurality of loads. The first power converter includes a first transformer circuit and a second transformer circuit. The output terminal of the first transformer circuit of the first power converter is connected to a portion of the loads; the output terminal of the second transformer circuit of the first power converter is connected to at least a portion of another portion of the loads. The second power converter also includes a first transformer circuit and a second transformer circuit. The output terminal of the first transformer circuit of the second power converter is connected to a portion of the loads; the output terminal of the second transformer circuit of the second power converter is connected to at least a portion of another portion of the loads. Under normal operation of the first power converter, the first transformer circuit of the first power converter supplies power to a portion of the loads, and the second transformer circuit of the first power converter supplies power to at least a portion of another portion of the loads; or, the first transformer circuit and the first transformer circuit of the first power converter jointly supply power to a portion of the loads, and the second transformer circuit of the first power converter and the second transformer circuit of the second power converter jointly supply power to at least a portion of another portion of the loads. In the event of a malfunction in the first power converter, the first transformer circuit of the second power converter supplies power to a portion of the loads, and the second transformer circuit of the second power converter supplies power to at least a portion of another portion of the loads.

[0007] In the aforementioned computing device, the first transformer circuit of the first power converter and the first transformer circuit of the second power converter are connected to a portion of the loads among the multiple loads, thus both the first transformer circuit of the first power converter and the first transformer circuit of the second power converter can supply power to a portion of the multiple loads. The second transformer circuit of the first power converter and the second transformer circuit of the second power converter are connected to at least a portion of another portion of the multiple loads, thus both the second transformer circuit of the first power converter and the second transformer circuit of the second power converter can be at least a portion of another portion of the multiple loads.

[0008] When switching from the first power converter to the second power converter to power multiple loads, the output power of the first transformer circuit of the second power converter increases from zero to the first operating power. At this time, the sudden increase in the output power of the first transformer circuit equals the first operating power and is less than the load power of the computing device. Conversely, when the second transformer circuit of the second power converter powers a second type of load, its output power increases from zero to the second operating power. The sudden increase in the output power of the first transformer circuit equals the second operating power and is less than the load power of the computing device.

[0009] When multiple loads are jointly powered by the first and second power converters, and the power supply switches to the second power converter, the output power of the first transformer circuit of the second power converter increases from 50% of the first operating power to the first operating power. At this time, the sudden increase in output power of the first transformer circuit is approximately 50% of the first operating power. Conversely, the output power of the second transformer circuit increases from 50% of the second operating power to the second operating power. At this time, the sudden increase in output power of the second transformer circuit is approximately 50% of the second operating power. Both the sudden increases in output power of the first and second transformer circuits are less than the load power of the computing device.

[0010] In related technologies, the maximum value of the output power fluctuation of the transformer circuit of the second power converter can reach the load power of the computing device, thus causing a voltage dip phenomenon. However, in some embodiments of this application, when the first power converter malfunctions, the output power fluctuation values ​​of both the first and second transformer circuits of the second power converter are less than the load power of the computing device. Therefore, this application can reduce the output power fluctuation value of the transformer circuits (including the first and second transformer circuits) of the second power converter, thereby improving the voltage dip phenomenon and thus mitigating the load power failure issue.

[0011] In one possible implementation, the first power converter further includes a plug-in portion, which includes a first conductive portion and a second conductive portion spaced apart. The output terminal of the first transformer circuit of the first power converter is connected to the first conductive portion, and a portion of the loads among the multiple loads are connected through the first conductive portion. The output terminal of the second transformer circuit of the first power converter is connected to the second conductive portion, and at least a portion of another portion of the loads among the multiple loads are connected through the second conductive portion.

[0012] The first and second conductive portions are spaced apart to insulate them from each other. The first conductive portion of the first power converter is electrically connected between the first transformer circuit of the first power converter and a portion of the loads in a plurality of loads, thereby enabling the first transformer circuit of the first power converter to supply power to a portion of the loads. The second conductive portion is electrically connected between the second transformer circuit of the first power converter and at least a portion of another portion of the loads in a plurality of loads, thereby enabling the second transformer circuit of the first power converter to supply power to at least a portion of the other portion of the loads.

[0013] In one possible implementation, the second power converter further includes a plug-in portion comprising a first conductive portion and a second conductive portion spaced apart. The output terminal of the first transformer circuit of the second power converter is connected to the first conductive portion, and a portion of the loads among the plurality of loads are connected through the first conductive portion. The output terminal of the second transformer circuit of the second power converter is connected to the second conductive portion, and at least a portion of another portion of the loads among the plurality of loads are connected through the second conductive portion.

[0014] The first conductive portion of the second power converter is electrically connected between the first transformer circuit of the second power converter and a portion of the loads among the plurality of loads, thereby enabling the first transformer circuit of the second power converter to supply power to a portion of the loads. The second conductive portion of the second power converter is electrically connected between the second transformer circuit of the second power converter and at least a portion of another portion of the loads among the plurality of loads, thereby enabling the second transformer circuit of the second power converter to supply power to at least a portion of another portion of the loads among the plurality of loads.

[0015] In one possible implementation, the computing device further includes a first connection portion and a second connection portion, a first conductor of a first power converter connected to the first connection portion, a portion of a plurality of loads connected to the first connection portion, a second conductor of the first power converter electrically connected to the second connection portion, and at least a portion of another portion of the plurality of loads connected to the second connection portion.

[0016] The first transformer circuit of the first power converter can be electrically connected to a portion of the multiple loads via a first conductive part and a first connecting part, thereby supplying power to a portion of the multiple loads. The second transformer circuit of the first power converter can be electrically connected to at least a portion of another portion of the multiple loads via a second conductive part and a second connecting part, thereby supplying power to at least a portion of the other portion of the multiple loads.

[0017] In one possible implementation, the first conductive portion of the second power converter is connected to the first connecting portion, and the second conductive portion of the second power converter is electrically connected to the second connecting portion.

[0018] In this configuration, the first conductive portion of the second power converter is connected to the first connecting portion, and the first connecting portion is connected to a portion of the multiple loads. Thus, the first transformer circuit of the second power converter can supply power to a portion of the multiple loads. The second conductive portion of the second power converter is electrically connected to the second connecting portion, and the second connecting portion is connected to at least a portion of another portion of the multiple loads. Thus, the second transformer circuit of the second power converter can supply power to at least a portion of the other portion of the multiple loads.

[0019] In one possible implementation, the computing device further includes a motherboard, on which a first receiving unit and a second receiving unit are disposed. The first receiving unit is electrically connected to a first connecting unit, and the second receiving unit is electrically connected to a second connecting unit. A portion of the plurality of loads is electrically connected to the first receiving unit, and at least a portion of another portion of the plurality of loads is electrically connected to the second receiving unit. Specifically, at least a portion of the portion of the plurality of loads is disposed on the motherboard; and at least a portion of another portion of the plurality of loads is disposed on the motherboard.

[0020] The first receiving unit is electrically connected between the first connecting unit and a portion of the multiple loads, thereby enabling the first transformer circuit of the first power converter and the first transformer circuit of the second power converter to supply power to the portion of the multiple loads via the first conductive part, the first connecting part, and the first receiving unit. The second receiving unit is electrically connected between the second connecting part and at least a portion of another portion of the multiple loads, thereby enabling the second transformer circuit of the first power converter and the second transformer circuit of the second power converter to supply power to at least a portion of the other portion of the multiple loads via the second conductive part, the second connecting part, and the second receiving unit.

[0021] In one possible implementation, the first power converter further includes a first connector and a second connector, the first connector including a first conductive portion and the second connector including a second conductive portion. Within the first power converter, the first conductive portion can be connected to a first transformer circuit of the first power converter, and the second conductive portion can be connected to a second transformer circuit of the first power converter. The second power converter also includes a first connector and a second connector, the first connector including a first conductive portion and the second connector including a second conductive portion. Within the second power converter, the first conductive portion can be connected to a first transformer circuit of the second power converter, and the second conductive portion can be connected to a second transformer circuit of the second power converter.

[0022] In this configuration, a first conductive portion of the first power converter is electrically connected between the first transformer circuit of the first power converter and a portion of the loads among multiple loads, thereby enabling the first transformer circuit of the first power converter to supply power to a portion of the loads. A second conductive portion of the second power converter is electrically connected between the second transformer circuit of the first power converter and at least a portion of another portion of the loads among multiple loads, thereby enabling the second transformer circuit of the first power converter to supply power to at least a portion of the other portion of the loads. The second conductive portion of the second power converter is electrically connected between the first transformer circuit of the second power converter and a portion of the loads among multiple loads, thereby enabling the first transformer circuit of the second power converter to supply power to a portion of the loads among multiple loads. The second conductive portion of the second power converter is electrically connected between the second transformer circuit of the second power converter and at least a portion of another portion of the loads among multiple loads, thereby enabling the second transformer circuit of the second power converter to supply power to at least a portion of the other portion of the loads.

[0023] In one possible implementation, at least a portion of another load among the multiple loads is a second type of load, the operating voltage of which differs from the output voltage of the second transformer circuit. The computing device further includes: a voltage regulating circuit, the input of which is connected to the output of the second transformer circuit of the first power converter and the output of the second transformer circuit of the second power converter; the output of which is connected to the second type of load; the voltage regulating circuit is used to adjust the voltage of the DC signal output by the second transformer circuit of the first power converter and / or the second transformer circuit of the second power converter to the operating voltage of the second type of load, and to transmit the voltage-adjusted DC signal to the second type of load.

[0024] By incorporating a voltage regulating circuit within the computing device, the voltage of the DC signal output by the second transformer circuit can be adjusted, and the adjusted DC signal can be transmitted to the second type of load to supply power. Therefore, by implementing the voltage regulating circuit, the second transformer circuit can still supply power to the second type of load even when the operating voltage of the second type of load differs from the output voltage of the second transformer circuit.

[0025] In one possible implementation, the second type of load includes at least two loads, wherein the operating voltages of the at least two loads of the second type of load are different; the number of voltage regulating circuits is at least two, the output of one voltage regulating circuit is connected to at least one load of the second type of load, and the operating voltages of the loads connected to different voltage regulating circuits are different.

[0026] In this design, by setting at least two voltage regulating circuits, a second transformer circuit can supply power to a second type of load with different operating voltages.

[0027] In one possible implementation, the computing device further includes a control chip electrically connected to the second transformer circuit of the first power converter and the second transformer circuit of the second power converter. The control chip is configured to: repeatedly change the output voltage of the second transformer circuit of the target power converter and obtain the total power of the computing device corresponding to the output voltage; and determine the minimum total power based on the repeatedly obtained total power, and control the output voltage of the second transformer circuit of the target power converter to adjust to a set output voltage, wherein the set output voltage is the output voltage corresponding to the minimum total power, and at least one of the first power converter and the second power converter is the target power converter.

[0028] The control chip can continuously adjust the output voltage of the second transformer circuit multiple times and obtain multiple overall power consumption values ​​corresponding to these output voltages. After determining the minimum overall power consumption, the control chip can adjust the output voltage of the second transformer circuit of the target power converter to the set output voltage. This reduces the overall power consumption of the computing device, thereby reducing its energy consumption.

[0029] In one possible implementation, the first power converter further includes a processing chip electrically connected to the second transformer circuit of the first power converter; the second power converter also includes a processing chip electrically connected to the second transformer circuit of the second power converter; both the processing chips of the first and second power converters are electrically connected to a control chip; the control chip is used to: repeatedly issue voltage adjustment commands to the processing chip of the target power converter; the processing chip of the target power converter is used to: change the output voltage of the second transformer circuit of the target power converter based on the voltage adjustment commands; the control chip is used to: issue control commands to the processing chip of the target power converter according to the lowest overall power consumption; the processing chip of the target power converter is used to: control the output voltage of the second transformer circuit of the target power converter to adjust to a set output voltage based on the control commands.

[0030] The control chip and processing chip are electrically connected, allowing the voltage adjustment commands issued by the control chip to be transmitted to the processing chip. The control chip can then continuously and repeatedly change the output voltage of the second transformer circuit of the target power converter through the processing chip. Each time the processing chip receives a voltage adjustment command, it can adjust the output voltage of the second transformer circuit of the target power converter accordingly. After determining the minimum overall power consumption, the control chip can issue a control command to the processing chip of the target power converter. This control command is transmitted to the processing chip. Upon receiving the control command, the processing chip can adjust the output voltage of the second transformer circuit of the target power converter to the set output voltage.

[0031] For example, the processing chip can be a DSP (Digital Signal Processing) chip.

[0032] For example, the control chip can be a baseboard management controller.

[0033] In one possible implementation, the processing chip of the first power converter is used to: acquire the input power of the first power converter and send it to the control chip; the processing chip of the second power converter is used to: acquire the input power of the second power converter and send it to the control chip; the control chip is used to: determine the overall power based on the input power of the first power converter and the input power of the second power converter.

[0034] In computing devices, not only the load generates energy consumption, but the power converter also generates energy consumption. Therefore, determining the overall power based on the input power of the first power converter and the input power of the second power converter can ensure the accuracy of the obtained overall power.

[0035] In one possible implementation, a portion of the multiple loads is a first type of load, which includes multiple loads; each load in the first type of load has the same operating voltage, and the same output voltage as the first transformer circuit.

[0036] In this case, the output voltage of the first type of load is the same as that of the first transformer circuit. Therefore, the DC power provided by the first transformer circuit of the first power converter and the first transformer circuit of the second power converter can be directly output to the first type of load to supply power to the first type of load.

[0037] For example, if multiple Class I loads are operating at 12V, then the output voltage of the first transformer circuit of at least two power converters is also 12V.

[0038] In one possible implementation, a portion of the loads includes at least one of a hard disk, a fan, and a high-speed serial bus card; at least a portion of another portion of the loads includes at least one of a central processing unit, dual in-line memory module, complex programmable logic device, and board management controller.

[0039] Specifically, by making the first transformer circuit of the first power converter and the first transformer circuit of the second power converter both electrically connected to a portion of the loads among multiple loads, and the second transformer circuit of the first power converter and the second transformer circuit of the second power converter both electrically connected to at least a portion of another portion of the loads among multiple loads, the phenomenon of power failure in hard drives, fans, high-speed serial bus cards, central processing units, dual in-line memory modules, complex programmable logic devices, and baseboard management controllers can be improved.

[0040] In one possible implementation, the output of the second transformer circuit of the first power converter is connected to a portion of another load among the plurality of loads; the output of the second transformer circuit of the second power converter is connected to a portion of another load among the plurality of loads; the first power converter further includes a third transformer circuit, the output of which is connected to another portion of another load among the plurality of loads; the second power converter further includes a third transformer circuit, the output of which is connected to another portion of another load among the plurality of loads.

[0041] By setting a third transformer circuit in the first and second power converters, and electrically connecting the third transformer circuit to a third type of load, the power of the load carried by any transformer circuit can be reduced. Thus, when the target power converter changes, the output power fluctuation value of the transformer circuit of the second power converter can be reduced, thereby improving the phenomenon of voltage drops in the transformer circuit and thus improving the phenomenon of power loss in the load.

[0042] On the other hand, a power converter is provided. The display device includes a first transformer circuit and a second transformer circuit, the output terminal of the first transformer circuit being used to connect to a portion of a plurality of loads, and the output terminal of the second transformer circuit being used to electrically connect to at least a portion of another portion of the plurality of loads, wherein the plurality of loads are loads in a computing device.

[0043] The power converters provided in the above embodiments can be used in the computing devices provided in the above embodiments. Both the first power converter and the second power converter in the computing device can be the power converters provided in the above embodiments, thereby reducing the output power fluctuation value of the transformer circuit (including the first transformer circuit and the second transformer circuit) of the second power converter in the computing device, and thus improving the phenomenon of voltage dips in the transformer circuit, thereby improving the phenomenon of load power failure.

[0044] In one possible implementation, the power converter further includes a connector, which includes a first conductive part and a second conductive part spaced apart. The output terminal of the first transformer circuit of the power converter is connected to the first conductive part, which is used to connect a portion of the loads among a plurality of loads. The output terminal of the second transformer circuit of the power converter is connected to the second conductive part, which is used to connect at least a portion of another portion of the loads among the plurality of loads.

[0045] The first transformer circuit is connected to the first conductive part, which is used to connect to a first type of load. Therefore, the first transformer circuit can supply power to the first type of load through the first conductive part. The second transformer circuit is connected to the second conductive part, and thus the second transformer circuit can supply power to the first type of load through the second conductive part.

[0046] In one possible implementation, the output of the second transformer circuit is connected to a portion of another load among multiple loads. The power converter also includes a third transformer circuit, the output of which is connected to another portion of the other load among multiple loads.

[0047] Specifically, by setting a third transformer circuit in the power converter and electrically connecting the third transformer circuit to a third type of load, the power of any transformer circuit can be reduced. Thus, when the target power converter of the computing device changes, the output power fluctuation value of the transformer circuit of the second power converter can be reduced, thereby improving the phenomenon of voltage drops in the transformer circuit and thus improving the phenomenon of power loss in the load.

[0048] In one possible implementation, the power converter's connector may further include a third connector spaced apart from the first connector, the third connector also spaced apart from the second connector, a third transformer circuit electrically connected to the third connector, and the third connector being used to connect to another portion of another load among a plurality of loads.

[0049] The third conductor can be electrically connected between the third transformer circuit and another part of the load among multiple loads, so that the third transformer circuit can supply power to the other part of the load among multiple loads through the third conductor.

For example, a central processing unit (CPU), DIMM memory, network card, PCIe card, complex programmable logic device (CPL), and board management controller can be located on motherboard 800. A power converter 300 can be electrically connected to motherboard 800, and motherboard 800 has multiple conductive lines, through which power converter 300 can supply power to the CPU, DIMM memory, and other devices. In addition, loads such as hard drive 210 and fans can be located outside motherboard 800, but can be electrically connected to it. In this case, power converter 300 can supply power to the hard drive 210 and fans located outside motherboard 800 through motherboard 800.

[0094] The computing device 1000 may also include a power connector 900. The power connector 900 may be located within the housing 100 (e.g., Figure 1 The power connector 900 is internal to the plug-in part 390. One end of the power connector 900 can be plugged into and electrically connected to the plug-in part 390, and the other end can be electrically connected to the motherboard 800. Thus, the power converter 300 can supply power to multiple loads on the motherboard 800 through the power connector 900.

[0095] In some examples, the motherboard 800 is provided with a receiver that can be electrically connected to multiple loads provided on the motherboard 800.

[0096] In addition, the motherboard 800 has multiple conductive connection wires. One end of each conductive connection wire is electrically connected to the receiving unit, and the other end is electrically connected to the hard drive 210 (e.g., Figure 1 As shown, the power connector 900 can supply power to the hard drive 210 and other components such as fans through the power connector 900, the receiving part, and the conductive connecting wires.

[0097] Figure 4 for Figure 3 Block diagram of the power converter 300.

[0098] Please see Figure 4 The power converter 300 may also include a filter circuit 320, a rectifier circuit 330, a power factor correction (PFC) circuit 340, and a transformer circuit 350.

[0099] The power input interface 310 is used to connect to a power source and receive AC power from the power grid.

[0100] The filter circuit 320 is electrically connected to the power input interface 310. The filter circuit 320 can filter out sudden pulses and high-frequency interference in the AC power received by the power input interface 310, and can reduce the electromagnetic interference of the power converter 300 to the power grid.

[0101] The rectifier circuit 330 can be electrically connected to the filter circuit 320, and the rectifier circuit 330 can convert alternating current into direct current. For example, the rectifier circuit 330 may include a half-wave rectifier circuit or a full-wave rectifier circuit.

[0102] The power factor correction circuit 340 can be electrically connected to the rectifier circuit 330, and the power factor correction circuit 340 can improve the power factor of the power converter 300. For example, the power factor correction circuit 340 may include electronic components such as switching transistors, inductors, and capacitors.

[0103] The transformer circuit 350 can be electrically connected to the rate factor correction circuit 340, and the transformer circuit 350 can convert the high voltage DC signal into a low voltage DC signal.

[0104] The transformer circuit 350 can be electrically connected to the connector 390 (e.g. Figure 3 As shown), the low-voltage DC signal generated by the transformer circuit 350 can be output through the connector 390.

[0105] Figure 5 for Figure 1The structural block diagram of the computing device 1000. It should be noted that... Figure 5 The circuit of the power converter 300 is omitted, and only the power factor correction circuit 340 and the transformer circuit 350 of the power converter 300 are shown.

[0106] Please see Figure 5 In some embodiments, the computing device 1000 may include a plurality of power converters 300, each of which can power a plurality of loads within the computing device 1000. Figure 4 In this paper, taking two power converters 300 as an example, some embodiments of this application will be illustrated by way of example.

[0107] For example, the two power converters 300 are a first power converter 301 and a second power converter 302, which can both provide power to loads such as hard disk 210, fan 220, PCIe standard card 230, central processing unit 410, DIMM memory 420, complex programmable logic device 430, baseboard management controller 440 and GPU.

[0108] In some embodiments, the power converter 300 includes a transformer circuit 350 electrically connected to the power factor correction circuit 340. The transformer circuit 350 of the first power converter 301 is electrically connected to multiple loads in the computing device 1000, and the transformer circuit 350 of the second power converter 302 is also electrically connected to multiple loads in the computing device 1000. Both the first power converter 301 and the second power converter 302 can be used to power multiple loads.

[0109] In this power converter, one of the first power converter 301 and the second power converter 302 is the main power supply, and the other is a backup power supply. One of the main power supply and the backup power supply can power multiple loads. The output voltage of the main power supply is higher than the output voltage of the backup power supply, so that the main power supply powers the loads, while the backup power supply does not. When the main power supply fails, the backup power supply then powers the loads.

[0110] For example, when the main power supply powers multiple loads, the main power supply outputs 12.3V, while the backup power supply outputs 12.05V.

[0111] For example, when the first power converter 301 acts as the main power supply to power multiple loads, the output power of the transformer circuit 350 of the first power converter 301 is 100% of the load power of the computing device 1000. The output power of the transformer circuit 350 of the second power converter 302 is zero. However, if the first power converter 301 fails, the second power converter 302 begins to supply power to multiple loads. At this time, the output power of the transformer circuit 350 of the second power converter 302 can suddenly increase from zero to 100% of the load power of the computing device 1000. The larger the load power of the computing device 1000, the larger the sudden increase in the output power of the transformer circuit 350. It should be noted that in several embodiments of this application, the load power of the computing device 1000 refers to the sum of the power of all loads in the computing device 1000. The sudden increase in output power refers to the difference between the output power of the transformer circuit 350 before the power converter supplies power to multiple loads and the output power of the transformer circuit 350 after the power converter supplies power to multiple loads.

[0112] As the computing power of computing device 1000 increases, its load power gradually increases. This leads to larger sudden changes in the output power of transformer circuit 350 in second power converter 302, making it prone to voltage dips. Consequently, the output voltage of transformer circuit 350 may fall below the operating voltage of some loads, causing partial load power loss. It should be noted that a voltage dip in transformer circuit 350 refers to a sudden decrease in output voltage followed by an increase.

[0113] Based on this, this application provides a computing device 1000. Figure 6 Provided for the embodiments of this application Figure 1 Another structural block diagram of the computing device 1000. Please refer to... Figure 6 The computing device 1000 includes at least two power converters 300 and multiple loads. It should be noted that... Figure 6 In this paper, taking the computing device 1000 including two power converters 300 as an example, some embodiments of this application are illustrated by way of example. It is understood that in this application, the number of power converters 300 is not limited to two, but may be three, four or even more.

[0114] The power converter 300 may include multiple transformer circuits 350, the input terminals of which are electrically connected to a power factor correction circuit 340. The number of transformer circuits 350 may be two or more. Figure 6In this paper, taking a power converter 300 including two transformer circuits 350 as an example, some embodiments of this application are illustrated by way of example. It is understood that in this application, the number of transformer circuits 350 in a power converter 300 is not limited to two, but can be three, four or even more.

[0115] As the computing power of the computing device 1000 gradually increases, the load power of the computing device 1000 gradually increases. By setting multiple transformer circuits 350 in the power converter 300, the output power of the power converter 300 can be improved.

[0116] At least two power converters 300 include a first power converter 301 and a second power converter 302.

[0117] The first power converter 301 includes a first transformer circuit 351 and a second transformer circuit 352. The output terminal of the first transformer circuit 351 is connected to a portion of the multiple loads; the output terminal of the second transformer circuit 352 is connected to at least a portion of another portion of the multiple loads. In the first power converter 301, the input terminals of both the first transformer circuit 351 and the second transformer circuit 352 are connected to a power factor correction circuit 340.

[0118] The second power converter 302 includes a first transformer circuit 351 and a second transformer circuit 352. The output terminal of the first transformer circuit 351 is connected to a portion of the loads among multiple loads; the output terminal of the second transformer circuit 352 is connected to at least a portion of another portion of the loads among multiple loads. In the second power converter 302, the input terminals of both the first transformer circuit 351 and the second transformer circuit 352 are connected to a power factor correction circuit 340. It should be noted that the aforementioned "at least a portion of the other portion of the loads" can be either a portion of the loads other than those connected to the first transformer circuit 351, or all of the loads other than those connected to the first transformer circuit 351.

[0119] For ease of description, some of the aforementioned loads are defined as first-class loads 200, which are connected to the first transformer circuit 351 of the first power converter 301 and the first transformer circuit 351 of the second power converter 302. At least a portion of the other loads are defined as second-class loads 400. Second-class loads 400 are electrically connected to the second transformer circuit 352 of the first power converter 301 and the second transformer circuit 352 of the second power converter 302. It should be noted that first-class loads 200 are the collection of loads connected to the first transformer circuit 351, and may include one or more of the multiple loads. Second-class loads 400 are the collection of loads connected to the second transformer circuit 352, and may include one or more loads. It is understood that the loads included in first-class loads 200 and second-class loads 400 are different.

[0120] For example, when the computing device 1000 has only a first type of load 200 and a second type of load 400, the second type of load 400 is all the loads except for the first type of load 200. When the computing device has other types of loads besides the first type of load 200 and the second type of load 400, the second type of load 400 is part of the loads except for the first type of load 200.

[0121] The output terminals of the first transformer circuits 351 of both power converters 300 (including the first power converter 301 and the second power converter 302) are electrically connected to the first type of load 200. For example, the output terminals of the first transformer circuits 351 can be connected to multiple loads in the first type of load 200. Alternatively, the output terminals of the first transformer circuits 351 can be connected to wires, which in turn are connected to multiple loads in the first type of load 200, thereby allowing the output terminals of the first transformer circuits 351 to be electrically connected to the loads in the first type of load 200.

[0122] The output terminals of the second transformer circuits 352 of both power converters 300 (including the first power converter 301 and the second power converter 302) are electrically connected to the second type of load 400. For example, the output terminals of the second transformer circuits 352 can be connected to multiple loads in the second type of load 400. Alternatively, the output terminals of the second transformer circuits 352 can be connected to wires, which in turn are connected to multiple loads in the second type of load 400, thereby allowing the output terminal of the first transformer circuit 351 to be electrically connected to a load in the second type of load 400.

[0123] The output terminals of the first transformer circuit 351 and the second transformer circuit 352 are electrically connected to the first type of load 200 and the second type of load 400, respectively. Thus, the DC power output by the first transformer circuit 351 can be transmitted to the first type of load 200 to supply power to the first type of load 200, and the DC power output by the second transformer circuit 352 can be transmitted to the second type of load 400 to supply power to the second type of load 400.

[0124] In some embodiments, at least one of the at least two power converters 300 is a target power converter. It should be noted that the power converter 300 used to power multiple loads at the current moment is the target power converter. The power converter 300 used to power multiple loads at the current moment can be one or more, that is, the number of target power converters can be one or more.

[0125] In one embodiment of this application, the power supply method of the computing device 1000 may include a primary / backup power supply method and a balanced power supply method. The primary / backup power supply method and the balanced power supply method will be described below using at least two power converters 300, including a first power converter 301 and a second power converter 302, as examples.

[0126] In the main and backup power supply mode, the first power converter 301 serves as the main power supply, while the second power converter 302 serves as the backup power supply.

[0127] When the first power converter 301 is functioning normally, its first transformer circuit 351 supplies power to a portion of the loads (i.e., the first type of load 200), and its second transformer circuit 352 supplies power to at least a portion of another portion of the loads (i.e., the second type of load 400). In this case, the first power converter 301 is the target power converter.

[0128] In the event of a malfunction in the first power converter 301, the system switches to a backup power supply (i.e., the second power converter 302) to power multiple loads. At this time, the first transformer circuit 351 of the second power converter 302 powers a portion of the loads (i.e., the first type of load 200), and the second transformer circuit 352 of the second power converter 302 powers at least a portion of another portion of the loads (i.e., the second type of load 400). In this case, the second power converter 302 becomes the target power converter.

[0129] In the case where "the first power converter 301 is normal", both the first transformer circuit 351 and the second transformer circuit 352 of the first power converter 301 can be used to supply power to the load to which they are electrically connected.

[0130] In the case of "First power converter 301 malfunction", the first power converter 301 fails, causing the first transformer circuit 351 and / or the second transformer circuit 352 to be unable to supply power to the loads they are electrically connected to.

[0131] When the main power supply (first power converter 301) supplies power to multiple loads, the first transformer circuit 351 of the first power converter 301 supplies power to the first type of load 200, while the second transformer circuit 352 of the first power converter 301 supplies power to the second type of load 400. At this time, the output power of the first transformer circuit 351 of the first power converter 301 is the first output power, and the first operating power is the sum of the operating power of all the first type of loads; therefore, the first output power equals the first operating power. Similarly, the output power of the second transformer circuit 352 of the first power converter 301 is the second output power, and the second operating power is the sum of the operating power of all the second type of loads; therefore, the second output power equals the second operating power. Since the second power converter 302 does not supply power to any load, the output power of both the first and second transformer circuits of the second power converter 302 is zero. The load power of the computing device 1000 is equal to the sum of the first and second operating powers.

[0132] When switching to the backup power supply (second power converter 302) to power multiple loads, the first transformer circuit 351 of the second power converter 302 powers the first type of load 200. At this time, the output power of the first transformer circuit 351 increases from zero to the first operating power. The sudden change in output power of the first transformer circuit 351 is equal to the first operating power and less than the load power of the computing device 1000. Conversely, the second transformer circuit 352 of the second power converter 302 powers the second type of load 400. At this time, the output power of the second transformer circuit 352 increases from zero to the second operating power. The sudden change in output power of the first transformer circuit 351 is equal to the second operating power and less than the load power of the computing device 1000.

[0133] In related technologies, the maximum value of the output power fluctuation of the transformer circuit 350 of the second power converter 302 can reach the load power of the computing device 1000, thus causing a voltage drop phenomenon. However, in some embodiments of this application, by electrically connecting the output terminals of the first transformer circuit 351 of both power converters 300 (including the first power converter 301 and the second power converter 302) to a first type of load 200, and electrically connecting the output terminals of the second transformer circuit 352 of both power converters 300 (including the first power converter 301 and the second power converter 302) to multiple second type of loads 400, the output power fluctuation value of the first transformer circuit 351 of the second power converter 302 can be set to a first operating power, and the output power fluctuation value of the second transformer circuit 352 of the second power converter 302 can be set to a second operating power. Both the first and second operating powers are less than the load power of the computing device 1000. Therefore, the embodiments of this application can reduce the output power fluctuation value of the transformer circuit 350, thereby improving the voltage drop phenomenon of the transformer circuit 350 and thus improving the load power loss phenomenon.

[0134] In a balanced power supply mode, at least two power converters 300 can supply power to multiple loads simultaneously. In this case, at least two power converters 300 are target power converters.

[0135] The balanced power supply method will be introduced below, taking at least two power converters 300, including a first power converter 301 and a second power converter 302, as an example.

[0136] When the first power converter 301 is functioning normally, the first transformer circuit 351 of the first power converter 301 and the first transformer circuit 351 of the second power converter 302 jointly supply power to a portion of the loads (i.e., the first type of load 200), and the second transformer circuit 352 of the first power converter 301 and the second transformer circuit 352 of the second power converter 302 jointly supply power to at least a portion of another portion of the loads (i.e., the second type of load 400). At this time, both the first power converter 301 and the second power converter 302 are target power converters.

[0137] In the event of a malfunction in the first power converter 301, the first power converter 301 stops supplying power to the first type of load 200 and the second type of load 400. At this time, the first transformer circuit 351 of the second power converter 302 supplies power to a portion of the loads (i.e., the first type of load 200), and the second transformer circuit 352 of the second power converter 302 supplies power to at least a portion of another portion of the loads (i.e., the second type of load 400). In this case, the second power converter 302 becomes the target power converter.

[0138] When the first power converter 301 and the second power converter 302 simultaneously supply power to the first type of load 200 and the second type of load 400, when the first power converter 301 and the second power converter 302 reach a stable state, the output power of the first transformer circuit 351 of the first power converter 301 and the first transformer circuit 351 of the second power converter 302 are approximately equal, and both are approximately 50% of the first operating power. Similarly, the output power of the second transformer circuit 352 of the first power converter 301 and the second transformer circuit 352 of the second power converter 302 are approximately equal, and both are approximately 50% of the second operating power.

[0139] When the first power converter 301 malfunctions, the second power converter 302 supplies power to the first type of load 200 and the second type of load 400. The output power of the first transformer circuit 351 of the second power converter 302 increases from 50% of the first operating power back to the first operating power. At this time, the sudden increase in output power of the first transformer circuit 351 of the second power converter 302 is approximately 50% of the first operating power. Conversely, the output power of the second transformer circuit 352 of the second power converter 302 increases from 50% of the second operating power back to the second operating power. At this time, the sudden increase in output power of the second transformer circuit 352 of the second power converter 302 is approximately 50% of the second operating power. Both the sudden increases in output power of the first transformer circuit 351 and the sudden increases in output power of the second transformer circuit 352 are less than the load power of the computing device 1000.

[0140] In related technologies, the maximum value of the output power fluctuation of the transformer circuit 350 of the second power converter 302 can reach the load power of the computing device 1000, thus causing a voltage drop phenomenon. However, in some embodiments of this application, in a balanced power supply mode, when the first power converter 301 malfunctions, the output power fluctuation values ​​of both the first transformer circuit 351 and the second transformer circuit 352 of the second power converter are less than the load power of the computing device 1000. Therefore, this application can reduce the output power fluctuation value of the transformer circuit 350 (including the first transformer circuit 351 and the second transformer circuit 352) of the second power converter, thereby improving the voltage drop phenomenon of the transformer circuit 350 and thus mitigating the load power loss phenomenon.

[0141] In some examples, the operating voltage of the first type of load 200 is the same as the output voltage of the first transformer circuit 351; the operating voltage of the second type of load 400 is the same as the output voltage of the second transformer circuit 352.

[0142] In other examples, the operating voltage of the first type of load 200 is the same as the output voltage of the first transformer circuit 351; the operating voltage of the second type of load 400 is different from the output voltage of the second transformer circuit 352.

[0143] In some other examples, the operating voltage of the first type of load 200 is different from the output voltage of the first transformer circuit 351; the operating voltage of the second type of load 400 is the same as the output voltage of the second transformer circuit 352.

[0144] In some other examples, the operating voltage of the first type of load 200 is different from the output voltage of the first transformer circuit 351; the operating voltage of the second type of load 400 is different from the output voltage of the second transformer circuit 352.

[0145] Specifically, when the operating voltage of the first type of load 200 is the same as the output voltage of the first transformer circuit 351, the operating voltage of one or more loads in the first type of load 200 is the same as the output voltage of the first transformer circuit 351. At this time, the DC power provided by the first transformer circuit 351 of the two power converters 300 can be directly output to the first type of load 200 to power the first type of load 200.

[0146] For example, the operating voltage of each load in the first type of load 200 is 12V. At this time, the output voltage of the first transformer circuit 351 of the first power converter 301 is 12V, and the output voltage of the first transformer circuit 351 of the second power converter 302 is also 12V.

[0147] For example, a portion of the loads (i.e., the first type of load 200) includes at least one of the hard drive 210, fan 220, and PCIe standard card 230.

[0148] When the operating voltage of the first type of load 200 differs from the output voltage of the first transformer circuit 351, if the first type of load 200 includes one load, the operating voltage of that load can be higher or lower than the output voltage of the first transformer circuit 351. If the first type of load 200 includes multiple loads, the operating voltages of all multiple loads in the first type of load 200 can be higher or lower than the output voltage of the first transformer circuit 351. In addition, the operating voltages of some loads in the first type of load 200 can be higher than the output voltage of the first transformer circuit 351, while the operating voltages of the remaining loads can be lower than the output voltage of the first transformer circuit 351.

[0149] When the operating voltage of the second type of load 400 is the same as the output voltage of the second transformer circuit 352, the operating voltage of one or more loads in the second type of load 400 is the same as the output voltage of the second transformer circuit 352. At this time, the DC power provided by the second transformer circuit 352 of the two power converters 300 can be directly output to the second type of load 400 to power the second type of load 400.

[0150] Figure 7 for Figure 1 Another structural block diagram of the computing device 1000.

[0151] Please see Figure 7 In cases where the operating voltage of the second type of load 400 differs from the output voltage of the second transformer circuit 352, in some examples, at least a portion of the loads in the second type of load 400 have an operating voltage higher than the output voltage of the second transformer circuit 352. In other examples, at least a portion of the loads in the second type of load 400 may have an operating voltage lower than the output voltage of the second transformer circuit 352. In still other examples, a portion of the loads in the second type of load 400 may have an operating voltage lower than the output voltage of the second transformer circuit 352, while the remaining loads may have an operating voltage higher than the output voltage of the second transformer circuit 352.

[0152] For example, at least a portion of another portion of the aforementioned loads (i.e., the second type of load 400) includes at least one of a central processing unit 410, a DIMM memory 420, a complex programmable logic device 430, and a baseboard management controller 440.

[0153] At this time, the computing device 1000 may further include: a voltage regulating circuit 500, the input terminal of which is connected to the output terminal of the second transformer circuit 352 of the first power converter 301 and the output terminal of the second transformer circuit 352 of the second power converter 302, and the output terminal of which is connected to the second type of load 400. The voltage regulating circuit 500 is used to adjust the voltage of the DC signal output by the second transformer circuit 352 of the first power converter 301 and / or the second transformer circuit 352 of the second power converter 302 to the operating voltage of the second type of load 400 electrically connected to the voltage regulating circuit 500, and to transmit the voltage-adjusted DC signal to the second type of load 400 electrically connected to the voltage regulating circuit 500. With this configuration, even when the operating voltage of the second type of load 400 is different from the output voltage of the second transformer circuit 352, the second transformer circuit 352 can still supply power to the second type of load 400.

[0154] When the second transformer circuit 352 of the first power converter 301 supplies power to the second type of load 400 alone, the voltage regulating circuit 500 adjusts the voltage of the DC signal output by the second transformer circuit 352 of the first power converter 301 to the operating voltage of the second type of load 400 electrically connected to the voltage regulating circuit 500.

[0155] When the second transformer circuit 352 of the second power converter 302 supplies power to the second type of load 400 alone, the voltage regulating circuit 500 adjusts the voltage of the DC signal output by the second transformer circuit 352 of the second power converter 302 to the operating voltage of the second type of load 400 electrically connected to the voltage regulating circuit 500.

[0156] When the second transformer circuit 352 of the first power converter 301 and the second transformer circuit 352 of the second power converter 302 jointly supply power to the second type of load 400, the voltage regulating circuit 500 adjusts the voltage of the DC signal output by the second transformer circuit 352 of the first power converter 301 and the second transformer circuit 352 of the second power converter 302 to the operating voltage of the second type of load 400 electrically connected to the voltage regulating circuit 500.

[0157] The voltage regulating circuit 500 can increase or decrease the voltage of the DC signal output by the second transformer circuit 352.

[0158] By incorporating a voltage regulating circuit 500 in the computing device 1000, the voltage of the DC signal output by the second transformer circuit 352 can be adjusted, and the adjusted DC signal can be transmitted to the second type of load 400 to supply power to it. Therefore, by incorporating the voltage regulating circuit 500, the second transformer circuit 352 can still supply power to the second type of load 400 even when the operating voltage of the second type of load 400 differs from the output voltage of the second transformer circuit 352.

[0159] In some embodiments, the second type of load 400 includes at least two loads, wherein the operating voltages of the at least two loads of the second type of load 400 are different. The number of voltage regulating circuits 500 is at least two, and the output of one voltage regulating circuit 500 is connected to at least one load of the second type of load 400, and the operating voltages of the loads electrically connected to different voltage regulating circuits 500 are different.

[0160] Each voltage regulating circuit 500 is electrically connected to all the second transformer circuits 352, and each second transformer circuit 352 is electrically connected to all the voltage regulating circuits 500.

[0161] In some examples, the second transformer circuit 352 can be electrically connected to different loads in the second type of load 400 via different voltage regulating circuits 500. One voltage regulating circuit 500 can be connected to one or more loads in the second type of load 400. Multiple loads connected to the same voltage regulating circuit 500 can have the same operating voltage; alternatively, multiple loads connected to the same voltage regulating circuit 500 can have different operating voltages.

[0162] By providing at least two voltage regulation circuits in the computing device 1000, the power converter 300 can supply power to loads with different operating voltages in the second type of load 400.

[0163] Please continue reading. Figure 7 In some examples, at least two voltage regulating circuits 500 include a first voltage regulating circuit 510 and a second voltage regulating circuit 520. The input terminal of the first voltage regulating circuit 510 is electrically connected to the output terminal of the second transformer circuit 352 of the first power converter 301 and the output terminal of the second transformer circuit 352 of the second power converter 302. The input terminal of the second voltage regulating circuit 520 is electrically connected to the output terminal of the second transformer circuit 352 of the first power converter 301 and the output terminal of the second transformer circuit 352 of the second power converter 302, and is also electrically connected to the input terminal of the second voltage regulating circuit 520.

[0164] In some examples, among the multiple loads in the second type of load 400, the load connected to the first voltage regulating circuit 510 can be defined as a first type of load 401, and the load connected to the second voltage regulating circuit 520 can be defined as a second type of load 402. The number of first type loads 401 can be at least one, and the number of second type loads 402 can be at least one.

[0165] The output terminal of the first voltage regulating circuit 510 is electrically connected to the first type of load 401, and the output terminal of the second voltage regulating circuit 520 is electrically connected to the second type of load 402. The first voltage regulating circuit 510 adjusts the voltage of the DC signal output from the second transformer circuit 352 to the operating voltage of the first type of load 401, and outputs the adjusted DC signal to the first type of load 401. The second voltage regulating circuit 520 adjusts the voltage of the DC signal output from the second transformer circuit 352 to the operating voltage of the second type of load 402, and outputs the adjusted DC signal to the second type of load 402.

[0166] In some examples, the operating voltage of the first load 401 may be less than or greater than the output voltage of the second transformer circuit 352.

[0167] For example, at least one of the central processing unit 410 and DIMM memory 420 is the first load 401.

[0168] When there are multiple first-type loads 401, the multiple first-type loads 401 can have different operating voltages. At this time, the first voltage regulating circuit 510 can output DC signals with different voltages.

[0169] For example, the first voltage regulating circuit 510 is a VRD (Voltage Regulation Or Down) circuit, and the output of the VRD circuit is electrically connected to the central processing unit 410 and the DIMM memory 420. The operating voltage of the central processing unit 410 is 1.8V, and the operating voltage of the DIMM memory 420 is 1.2V. The first voltage regulating circuit 510 can provide two DC signals with voltages of 1.8V and 1.2V respectively.

[0170] In some examples, there can be one or more second-type loads 402. When there are multiple second-type loads 402, the operating voltages of the multiple second-type loads 402 can be the same or different.

[0171] In some examples, the operating voltage of the second load 402 may be less than or greater than the output voltage of the second transformer circuit 352.

[0172] For example, the operating voltage of multiple second-type loads 402 is the second operating voltage. The second voltage regulating circuit 520 is used to adjust the voltage value of the DC signal output by the second transformer circuit 352 to the second operating voltage, and output the voltage-adjusted DC signal to the second-type load 402.

[0173] For example, at least one of the complex programmable logic device 430 and the substrate management controller 440 can be a second load 402. The operating voltage of both the complex programmable logic device 430 and the substrate management controller 440 is 3.3V.

[0174] For example, the output voltage of the second transformer circuit 350 is 12V.

[0175] In some of the above embodiments, when the operating voltage of the second type of load 400 is different from the output voltage of the second transformer circuit 352, a voltage regulating circuit 500 can be provided between the second type of load 400 and the second transformer circuit 352. The voltage regulating circuit 500 can adjust the voltage of the DC signal output to the second type of load 400, so that the second transformer circuit 352 can supply power to the second type of load 400.

[0176] It is understandable that when the operating voltage of the first type of load 200 is different from the output voltage of the first transformer circuit 351, another voltage regulating circuit can be set between the first type of load 200 and the first transformer circuit 351. This voltage regulating circuit can adjust the voltage of the DC signal output to the first type of load 200, so that the first transformer circuit 351 can supply power to the first type of load 200.

[0177] Figure 8 for Figure 1 Another structural block diagram of the computing device 1000.

[0178] Please see Figure 8 In some embodiments, the computing device 1000 further includes a control chip 600, which is electrically connected to the second transformer circuit 352 of the first power converter 301 and the second transformer circuit 352 of the second power converter 302.

[0179] The control chip 600 is used to: repeatedly change the output voltage of the second transformer circuit 352 of the target power converter and obtain the total power of the computing device 1000 corresponding to the output voltage; and determine the minimum total power based on the multiple obtained total power, and control the output voltage of the second transformer circuit 352 of the target power converter to adjust to the set output voltage, wherein the set output voltage is the output voltage corresponding to the minimum total power, and at least one of the first power converter 301 and the second power converter 302 is the target power converter.

[0180] The first transformer circuit 351 or the second transformer circuit 352 can be used to power the control chip 600.

[0181] The target power converter has already been introduced above, so it will not be repeated here.

[0182] The total power of the computing device 1000 is equal to the sum of the input power of all the power converters 300.

[0183] During the process of the control chip 600 changing the output voltage of the second transformer circuit 352 of the target power converter multiple times, the control chip 600 can control the output voltage of the second transformer circuit 352 of the target power converter to change at least twice. After each change of the output voltage of the second transformer circuit, the control chip 600 will obtain the total power corresponding to the current output voltage.

[0184] For example, during the process of the control chip 600 changing the output voltage of the second transformer circuit 352 of the target power converter multiple times, the control chip 600 can control the output voltage of the second transformer circuit 352 of the target power converter to change five times. Correspondingly, the control chip 600 can obtain the total power of the machine five times.

[0185] After changing the output voltage of the second transformer circuit 352 of the target power converter for the last time and obtaining the total power corresponding to the output voltage, the lowest total power among the multiple obtained total power can be determined.

[0186] For example, during the process of the control chip 600 continuously changing the output voltage of the second transformer circuit 352 of the target power converter, the output voltage of the second transformer circuit 352 of the target power converter is successively a first voltage value, a second voltage value, a third voltage value, a fourth voltage value, and a fifth voltage value.

[0187] When the output voltage is the first voltage value, the control chip 600 obtains the current total power as the first total power.

[0188] When the output voltage is the second voltage value, the control chip 600 obtains the current total power as the second total power.

[0189] When the output voltage is the third voltage value, the control chip 600 obtains the current total power as the third total power.

[0190] When the output voltage is the fourth voltage value, the control chip 600 obtains the current total power as the fourth total power.

[0191] When the output voltage is the fifth voltage value, the control chip 600 obtains the current total power as the fifth total power.

[0192] After obtaining the fifth total power, the lowest total power among the first to fifth total power is determined. For example, if the lowest total power is the third total power, the output voltage is set to the third voltage value, and the control chip 600 controls the output voltage of the second transformer circuit 352 of the target power converter to adjust to the third voltage value.

[0193] The control chip 600 can adjust the output voltage of the second transformer circuit 352 of the target power converter to a set output voltage. With this configuration, the computing device 1000 can maintain a minimum overall power consumption, thereby reducing the energy consumption of the computing device 1000.

[0194] For example, the output voltage of the second transformer circuit 352 is greater than or equal to 9V and less than or equal to 14V.

[0195] In some examples, when the target power converter changes, the control chip 600 can change the output voltage of the second transformer circuit 352 of the target power converter multiple times, and obtain the total power of the computing device 1000 corresponding to the output voltage; and determine the minimum total power based on the multiple obtained total power, and control the output voltage of the second transformer circuit 352 of the target power converter to adjust to the set output voltage, wherein the set output voltage is the output voltage corresponding to the minimum total power.

[0196] In other examples, computing device 1000 may include an energy-saving mode. When computing device 1000 activates energy-saving mode, control chip 600 may repeatedly change the output voltage of the second transformer circuit 352 of the target power converter and obtain the total power of computing device 1000 corresponding to the output voltage; and determine the minimum total power based on the multiple obtained total power, and control the output voltage of the second transformer circuit 352 of the target power converter to adjust to the set output voltage, wherein the set output voltage is the output voltage corresponding to the minimum total power.

[0197] For example, computing device 1000 may include a power-saving mode activation button. For instance, the power-saving mode activation button may be a button located on the housing of computing device 1000. Alternatively, the power-saving mode activation button may be a virtual button.

[0198] Figure 9 for Figure 1 Another structural block diagram of the computing device 1000.

[0199] Please see Figure 9 In some embodiments, the first power converter 301 may further include a processing chip 360, which is electrically connected to the second transformer circuit 350 of the first power converter 301.

[0200] The second power converter 302 may also include a processing chip 360, which is electrically connected to the second transformer circuit 350 of the second power converter 302.

[0201] The processing chip 360 of the first power converter 301 and the processing chip 360 of the second power converter 302 are both electrically connected to the control chip 600.

[0202] For example, the control chip 600 may include a baseboard management controller 440.

[0203] For example, the processing chip 360 may include a DSP (Digital Signal Processing) chip.

[0204] For example, the control chip 600 and the processing chip 360 are electrically connected via an I2C (Inter-Integrated Circuit) bus. The I2C bus includes SDA (Serial Data Line) and SCL (Serial Clock Line).

[0205] The control chip 600 is used to send voltage regulation commands to the processing chip 360 of the target power converter multiple times.

[0206] The processing chip 360 of the target power converter is used to change the output voltage of the second transformer circuit 352 of the target power converter based on the voltage regulation command.

[0207] The control chip 600 is used to: acquire the total power of the computing device 1000 corresponding to the output voltage; determine the minimum total power based on the acquired total power, and send a control command to the processing chip 360 of the target power converter based on the minimum total power.

[0208] The processing chip 360 of the target power converter is used to: adjust the output voltage of the second transformer circuit 352 of the target power converter to a set output voltage based on control commands.

[0209] The control chip 600 is electrically connected to the processing chips 360 of both the first power converter 301 and the second power converter 302. Therefore, when either the first power converter 301 or the second power converter 302 is used as the target power converter, the control chip 600 can send voltage regulation commands to the processing chip 360 of the target power converter. For example, the control commands can be transmitted to the processing chip 360 via an I2C bus.

[0210] The processing chip 360 of the target power converter can change the output voltage of the second transformer circuit 352 of the target power converter according to the voltage adjustment command issued by the control chip 600. Therefore, the control chip 600 can change the output voltage of the second transformer circuit 352 of the target power converter by sending a voltage adjustment command to the processing chip 360 of the target power converter.

[0211] After the output voltage of the second transformer circuit 352 of the target power converter changes, the control chip 600 obtains the total power of the computing device 1000 corresponding to the output voltage, determines the minimum total power, and sends a control command to the processing chip 360 of the target power converter based on the minimum total power.

[0212] The processing chip 360 of the target power converter can adjust the output voltage of the second transformer circuit 352 of the target power converter to the set output voltage according to the control command issued by the control chip 600. Therefore, the control chip 600 can control the output voltage of the second transformer circuit 352 of the target power converter to be adjusted to the set output voltage by outputting control commands.

[0213] It is understandable that the power converter 300 already has a processing chip 360 inside, so the above functions can be achieved using the existing chip, thus avoiding the need to add other chips to the power converter 300.

[0214] In some other embodiments, the processing chip 360 may be located outside the power converter 300.

[0215] In some embodiments, the processing chip 360 of the first power converter 301 is used to: acquire the input power of the first power converter 301 and send it to the control chip 600. The processing chip 360 of the second power converter 302 is used to: acquire the input power of the second power converter 302 and send it to the control chip 600.

[0216] The control chip 600 is used to determine the overall power based on the input power of the first power converter 301 and the input power of the second power converter 302.

[0217] For example, the total power of computing device 1000 is equal to the sum of the input power of the first power converter 301 and the input power of the second power converter 302.

[0218] Please continue reading. Figure 9 In some examples, in the first power converter 301, the processing chip 360 is electrically connected to the input terminal of the power factor correction circuit 340. The processing chip 360 can obtain the current and voltage values ​​of the DC power input to the power factor correction circuit 340, and obtain the input power of the first power converter 301 based on the current and voltage values ​​of the DC power input to the power factor correction circuit 340. The input power of the first power converter 301 can be equal to the product of the aforementioned current and voltage values.

[0219] In the second power converter 302, the processing chip 360 is electrically connected to the input terminal of the power factor correction circuit 340. The processing chip 360 can acquire the current and voltage values ​​of the DC power input to the power factor correction circuit 340, and obtain the input power of the second power converter 302 based on the current and voltage values ​​of the DC power input to the power factor correction circuit 340. The input power of the second power converter 302 can be equal to the product of the aforementioned current and voltage values.

[0220] In the computing device 1000, not only the load generates energy consumption, but the power converter 300 also generates energy consumption. Therefore, determining the overall power based on the input power of each power converter 300 can ensure the accuracy of the obtained overall power.

[0221] In some examples, the processing chip 360 can also acquire the output power of each power converter 300 and send the output power of each power converter 300 to the substrate management controller 440, thereby enabling monitoring of the output power of the power converter 300.

[0222] For example, in the first power converter 301, the processing chip 360 can be electrically connected to the output terminals of the first transformer circuit 351 and the second transformer circuit 352 to obtain the output voltage and current of the first transformer circuit 351 and the second transformer circuit 352, and to obtain the output power of the first power converter 301 based on the output voltage and current of the first transformer circuit 351 and the second transformer circuit 352. The output power of the first power converter 301 can be equal to the product of the output voltage and current of the first transformer circuit 351 plus the product of the output voltage and current of the second transformer circuit 352.

[0223] For example, in the second power converter 302, the processing chip 360 can be electrically connected to the output terminals of the first transformer circuit 351 and the second transformer circuit 352 to obtain the output voltage and current of the first transformer circuit 351 and the second transformer circuit 352, and to obtain the output power of the second power converter 302 based on the output voltage and current of the first transformer circuit 351 and the second transformer circuit 352. The output power of the second power converter 302 can be equal to the product of the output voltage and current of the first transformer circuit 351 plus the product of the output voltage and current of the second transformer circuit 352.

[0224] In some examples, the processing chip 360 is used to acquire a set output voltage according to control instructions; and adjust the output voltage of the second transformer circuit 352 based on the set output voltage. After adjusting the output voltage of the second transformer circuit 352, the processing chip 360 acquires the actual output voltage of the second transformer circuit 352 of the target power converter. If the actual output voltage of the second transformer circuit 352 of the target power converter is different from the set output voltage, the output voltage of the second transformer circuit 352 is adjusted again until the actual output voltage of the second transformer circuit 352 is the same as the set output voltage.

[0225] Specifically, by acquiring the actual output voltage of the second transformer circuit 352 and adjusting the output voltage of the second transformer circuit 352 according to the actual output voltage of the second transformer circuit 352 until the actual output voltage of the second transformer circuit 352 is equal to the set output voltage, it can be ensured that the actual output voltage of the second transformer circuit 352 can be adjusted to the set output voltage corresponding to the minimum overall power, thereby ensuring that the computing device 1000 is kept at the minimum overall power.

[0226] For example, the processing chip 360 can output a PWM (Pulse Width Modulation) signal to the second transformer circuit 352 to adjust the output voltage of the second transformer circuit 352.

[0227] In some examples, the processing chip 360 can also be electrically connected to the first transformer circuit 351, and the processing chip 360 can control the output voltage of the first transformer circuit 351 to be fixed at 12V.

[0229] Please see Figure 10 In some embodiments, the first power converter 301 may further include a plug-in portion 390, which may include a first conductive portion 391 and a second conductive portion 392 spaced apart.

A first conductive portion 391 of the first power converter 301 is connected to the first connection portion 610. A portion of the loads (i.e., the first type of load 200) is connected to the first connection portion 610. A second conductive portion 392 of the first power converter 301 is electrically connected to the second connection portion 620. At least a portion of another portion of the loads (i.e., the second type of load 400) is connected to the second connection portion 620.

[0239] The first transformer circuit 351 of the first power converter 301 can be electrically connected to the first type of load 200 through the first conductive part 391 and the first connecting part 610, so that the first transformer circuit 351 of the first power converter 301 can supply power to the first type of load 200.

[0240] For example, the first connection part 610 can be a power supply bus.

[0262] In some embodiments, the computing device further includes a motherboard 800, on which a first receiving unit and a second receiving unit are disposed.

[0265] The second receiving unit is electrically connected between the second connecting unit and the plurality of second type loads 400, thereby the second transformer circuit 352 of the first power converter 301 and the second transformer circuit 352 of the second power converter 302 can supply power to the second type loads 400 through the second conductive part, the second connecting part and the second receiving unit.

[0266] In a subset of multiple loads (i.e., the first type of load 200), at least a portion of the load is located on the motherboard 800. In this case, at least a portion of the first type of load 200 is located on the motherboard 800. In some examples, a portion of the first type of load 200 is located on the motherboard 800, while the remaining portion is located outside the motherboard 800. In other examples, all of the first type of load 200 is located on the motherboard 800.

[0267] For example, the first type of load 200 can be electrically connected to the first receiving unit via conductive lines provided on the motherboard 800.

[0268] For example, the conductive lines on the motherboard 800 may include a first conductive line and a second conductive line. One end of the first conductive line may be connected to a first receiving unit, and the other end may be connected to a load disposed on the motherboard 800 in the first type of load 200.

The first connector may be electrically connected to a load disposed outside the motherboard 800 in the first type of load 200.

[0269] For example, in the first type of load 200, the PCIe card can be mounted on the motherboard 800, while the hard drive 210 and fan 220 can be mounted outside the motherboard 800. The motherboard 800 is provided with conductive connecting wires, one end of which is electrically connected to the first receiving unit, and the other end of which can be electrically connected to components such as the hard drive 210 and fan 220.

[0270] In a subset of multiple loads, at least a portion of the load (i.e., the second type of load 400) is located on the motherboard 800. In this case, at least a portion of the second type of load 400 is located on the motherboard; in some examples, a portion of the second type of load 400 is located on the motherboard 800, while the remaining portion is located outside the motherboard 800.

[0273] For example, in the second type of load 400, the central processing unit 410, DIMM memory 420, complex programmable logic device 430, and baseboard management controller 440 can be located on the motherboard 800.

[0274] Figure 12 for Figure 1 Another structural block diagram of the computing device 1000.

[0275] Please see Figure 12In some examples, the first power converter 301 may also include a fourth transformer circuit 354, which may be connected in parallel with the first transformer circuit 351. The input terminal of the fourth transformer circuit 354 is connected to the power factor correction circuit 340, and the output terminal of the fourth transformer circuit 354 is electrically connected to the first type of load 200. In this case, the first transformer circuit 351 and the fourth transformer circuit 354 of the first power converter 301 can jointly supply power to the first type of load 200.

[0276] In some examples, the output of the fourth transformer circuit 354 of the first power converter 301 may be electrically connected to the first conductor 391 of the first power converter 301.

[0277] In some examples, the second power converter 302 may also include a fourth transformer circuit 354. In the second power converter 302, the fourth transformer circuit 354 may be connected in parallel with the first transformer circuit 351. The input terminal of the fourth transformer circuit 354 is connected to the power factor correction circuit 340, and the output terminal of the fourth transformer circuit 354 is electrically connected to the first type of load 200. In this case, the first transformer circuit 351 and the fourth transformer circuit 354 of the first power converter 301 can jointly supply power to the first type of load 200.

[0278] In some examples, the output of the fourth transformer circuit 354 of the first power converter 301 may be electrically connected to the first conductor 391 of the second power converter 302.

[0279] It is understandable that a transformer circuit and a second transformer circuit 352 can be connected in parallel, and the two together supply power to the second type of load 400.

[0280] Figure 13 for Figure 1 Another structural block diagram of the computing device 1000.

[0281] Please see Figure 13 The output terminal of the second transformer circuit 352 of the first power converter 301 is connected to a portion of another load among multiple loads; the output terminal of the second transformer circuit 352 of the second power converter 302 is also connected to a portion of another load among multiple loads. At this time, the portion of another load among multiple loads is a second type of load.

[0282] The first power converter 301 also includes a third transformer circuit 353, the output of which is connected to another part of the load among multiple loads.

[0283] The second power converter 302 also includes a third transformer circuit 353, the output of which is connected to another portion of the load among multiple loads.

[0284] The input terminal of the third transformer circuit 353 of the first power converter 301 is connected to the output terminal of the power factor correction circuit 340 of the first power converter 301.

[0285] The input terminal of the third transformer circuit 353 of the second power converter 302 is connected to the output terminal of the power factor correction circuit 340 of the second power converter 302.

[0286] For ease of description, another part of the load among multiple loads is defined as the third type of load 700.

[0287] In some examples, the operating voltage of the third type load 700 may be equal to or different from the output voltage of the third transformer circuit 353.

[0288] When the operating voltage of the third type of load 700 is not equal to the output voltage of the third transformer circuit 353, a voltage regulator can be set between the third transformer circuit 353 and the third type of load 700. The voltage regulator can adjust the voltage of the DC signal output by the third transformer circuit 353 to the operating voltage of the third type of load 700, and output the adjusted DC signal to the third type of load 700 to supply power to the third type of load 700.

[0289] Figure 14 for Figure 1 Another structural block diagram of the computing device 1000.

[0290] Please see Figure 14 In some examples, the plug portion 390 of the first power converter 301 may also include a third conductor 393. The output terminal of the third transformer circuit 353 of the first power converter 301 is connected to the third conductor 393 of the first power converter 301. The third conductor 393 of the first power converter 301 is connected to the third type of load 700. In this way, the third transformer circuit 353 of the first power converter 301 can supply power to the third type of load 700 through the third conductor of the first power converter 301.

[0291] The plug-in portion 390 of the second power converter 302 may also include a third conductive portion 393. The output terminal of the third transformer circuit 353 of the second power converter 302 is connected to the third conductive portion 393 of the second power converter 302. The third conductive portion 393 of the second power converter 302 is connected to the third type of load 700. Thus, the third transformer circuit 353 of the second power converter 302 can supply power to the third type of load 700 through the third conductive portion 393.

[0292] In some examples, the computing device 1000 may also include a third connection portion electrically connected to the third conductor 393 of the first power converter 301 and the third conductor 393 of the second power converter 302. The third connection portion is also electrically connected to a third type of load 700.

[0293] For example, the motherboard 800 is also provided with a third receiving unit. The end of the third connecting part away from the third conductor 393 can be connected to the third receiving unit, and the third receiving unit is electrically connected to the third type of load 700.

[0294] The third receiving unit can be a conductive connection line installed on the motherboard.

[0295] Specifically, by setting a third transformer circuit 353 in the first power converter 301 and the second power converter 301, and electrically connecting the third transformer circuit 353 to the third type of load 700, the power of the load driven by any transformer circuit 350 can be reduced. In this way, when the target power converter changes, the output power fluctuation value of the transformer circuit 350 of the second power converter can be reduced, thereby improving the phenomenon of voltage drop in the output of the transformer circuit 350 and thus improving the phenomenon of power loss in the load.

[0296] Figure 15 for Figure 1 Another structural block diagram of the computing device 1000.

[0297] Please see Figure 15 In some examples, the power converter 300 includes a transformer circuit 350. In this case, the power converter 300 may include a connector 390, which may further include a fourth conductor 394 and a fifth conductor 395. The transformer circuit 350 is electrically connected to the power factor correction circuit 340, and the fourth conductor 394 and the fifth conductor 395 are electrically connected. The fourth conductor 394 may be electrically connected to a first-type load 200, and the fifth conductor 395 may be electrically connected to a second-type load 400. This configuration allows the power converter 300, which includes a transformer circuit 350, to supply power to both the first-type load 200 and the second-type load 400.

[0298] Figure 16This is a structural block diagram of a power converter 300 according to some embodiments.

[0299] Please see Figure 16 The power converter 300 may include multiple transformer circuits 350, the input terminals of which are electrically connected to a power factor correction circuit 340. The number of transformer circuits 350 may be two or more. Figure 16 In this paper, taking the power converter 300 including two transformer circuits 350 as an example, some embodiments of this application are illustrated by way of example. It is understood that in this application, the number of transformer circuits 350 in the power converter 300 is not limited to two, but can be three, four or even more.

[0300] As the computing power of the computing device 1000 gradually increases, the load power of the computing device 1000 gradually increases. By setting multiple transformer circuits 350 in the power converter 300, the output power of the power converter 300 can be improved.

[0301] Please see Figure 16 and combined Figure 6 The power converter 300 may include a first transformer circuit 351 and a second transformer circuit 352 among its multiple transformer circuits 350. The output terminal of the first transformer circuit 351 is used to connect to a portion of the loads (i.e., the first type of load 200) among the multiple loads, and the output terminal of the second transformer circuit 352 is used to be electrically connected to at least a portion of another portion of the multiple loads (i.e., the second type of load 400). The multiple loads are loads in a computing device.

[0302] The power converter 300 provided in some of the above embodiments can be used in the computing device 1000 provided in some of the above embodiments. Both the first power converter 301 and the second power converter 302 in the computing device 1000 can be the power converter 300 provided in some of the above embodiments. In this case, the output terminal of the first transformer circuit 351 of the first power converter 301 is connected to a first type of load 200, and the output terminal of the second transformer circuit 352 of the first power converter 301 is connected to a second type of load 400. The output terminal of the first transformer circuit 351 of the second power converter 302 is connected to the first type of load 200, and the output terminal of the second transformer circuit 352 of the second power converter 302 is connected to the second type of load 400.

[0303] When the power supply is switched from the first power converter 301 to the second power converter 302 to power multiple loads, the output power of the first transformer circuit 351 of the second power converter 302 increases from zero to the first operating power. At this time, the sudden change in the output power of the first transformer circuit 351 is equal to the first operating power and less than the load power of the computing device 1000. Meanwhile, the second transformer circuit 352 of the second power converter 302 is used to power the second type of load 400. At this time, the output power of the second transformer circuit 352 of the backup power supply increases from zero to the second operating power. The sudden change in the output power of the first transformer circuit 351 is equal to the second operating power and less than the load power of the computing device 1000.

[0304] When multiple loads are jointly powered by the first power converter 301 and the second power converter 302, and the power supply switches to the second power converter 302, the output power of the first transformer circuit 351 of the second power converter 302 increases from 50% of the first operating power to the first operating power. At this time, the sudden increase in output power of the first transformer circuit 351 of the second power converter 302 is approximately 50% of the first operating power. Conversely, the output power of the second transformer circuit 352 of the second power converter 302 increases from 50% of the second operating power to the second operating power. At this time, the sudden increase in output power of the second transformer circuit 352 of the second power converter 302 is approximately 50% of the second operating power. Both the sudden increases in output power of the first transformer circuit 351 and the sudden increases in output power of the second transformer circuit 352 are less than the load power of the computing device 1000.

[0305] In related technologies, the maximum value of the output power fluctuation of the transformer circuit 350 of the second power converter 302 can reach the load power of the computing device 1000, thus causing a voltage drop phenomenon. However, in some embodiments of this application, when the first power converter 301 malfunctions, the output power fluctuation values ​​of both the first transformer circuit 351 and the second transformer circuit 352 of the second power converter are less than the load power of the computing device 1000. Therefore, this application can reduce the output power fluctuation value of the transformer circuit 350 (including the first transformer circuit 351 and the second transformer circuit 352) of the second power converter, thereby improving the voltage drop phenomenon of the transformer circuit 350 and thus mitigating the load power loss phenomenon.

[0306] Figure 17 This is another structural block diagram of a power converter 300 according to some embodiments.

[0307] Please see Figure 17 and combined Figure 10In some embodiments, the power converter 300 further includes a plug-in portion 390, which includes a first conductive portion 391 and a second conductive portion 392 spaced apart. The output terminal of the first transformer circuit 351 of the power converter 300 is connected to the first conductive portion 391, and a portion of the loads (i.e., the first type of load 200) is connected through the first conductive portion 391. The output terminal of the second transformer circuit 352 of the power converter 300 is connected to the second conductive portion 392, and at least a portion of another load (i.e., the second type of load 400) is connected through the second conductive portion 392.

[0308] The first transformer circuit 351 is connected to the first conductive part 391, which is connected to the first type of load 200. Therefore, the first transformer circuit 351 can supply power to the first type of load 200 through the first conductive part 391. The second transformer circuit 352 is connected to the second conductive part 392, and thus the second transformer circuit 352 can supply power to the first type of load 200 through the second conductive part 392.

[0309] In other examples, the power converter 300 may include a first connector 3901 and a second connector 3902, wherein the first conductive portion 391 is disposed on the first connector 3901 and the second conductive portion 392 is disposed on the second connector 3902.

[0310] Figure 18 This is another structural block diagram of a power converter 300 according to some embodiments.

[0311] Please see Figure 18 and combined Figure 14 In some embodiments, the output of the second transformer circuit 352 is connected to a portion of another load among the plurality of loads. The power converter 300 also includes a third transformer circuit 353, the output of which is connected to another portion of another load among the plurality of loads (i.e., a third type of load 700).

[0312] By setting a third transformer circuit 353 in the power converter 300 and electrically connecting the third transformer circuit 353 to the third type of load 700, the power of the load driven by any transformer circuit 350 can be reduced. Therefore, when the target power converter of the computing device 1000 changes, the output power fluctuation value of the transformer circuit 350 of the second power converter can be reduced, thereby improving the phenomenon of voltage drops in the output of the transformer circuit 350 and thus improving the phenomenon of power loss in the load.

[0313] In some examples, the connector 390 includes a third conductor 393, which is spaced apart from the first conductor 391, and thus the third conductor 393 and the first conductor 391 are insulated from each other. The third conductor 393 is also spaced apart from the second conductor 392, and thus the third conductor 393 and the second conductor 392 are insulated from each other.

[0314] The third transformer circuit 353 is electrically connected to the third conductor 393 and can be electrically connected to the third type of load 700 through the third conductor 393, thereby supplying power to the third type of load 700.

[0315] In other examples, the power converter 300 may include a first connector 3901, a second connector 3902, and a third connector, wherein a first conductive part 391 is disposed in the first connector 3901, a second conductive part 392 is disposed in the second connector 3902, and a third conductive part 393 is disposed in the third connector.

[0316] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
