Description

Technical Field

[0001] This application relates to the field of computing device technology, and more particularly to a computing device. Background Technology

[0002] Computing devices, such as server nodes or rack-mount servers, typically include power conversion devices, power buses, and various types of loads. The power conversion devices supply power to the loads via the power bus. When the power supply from the power conversion devices is unstable, it cannot meet the power requirements of the loads, leading to unstable operation. Therefore, there is an urgent need to provide a solution to better meet the power requirements of the loads and improve their operational stability. Utility Model Content

[0003] This application provides a computing device that helps stabilize the power bus voltage when the load inside the computing device increases, the power supply voltage fluctuates, or the power supply fails, thereby better meeting the power supply needs of the load and improving the stability of the load operation.

[0004] To achieve the above objectives, the embodiments of this application provide the following technical solutions.

[0005] This application provides a computing device including a power conversion device, a power bus, a supercapacitor module, and a backup power module. The power conversion device, supercapacitor module, and backup power module are all connected to the power bus. The power conversion device supplies power to the power bus. The supercapacitor module discharges to the power bus when the voltage of the power bus is less than a first voltage and the output voltage of the backup power module is less than a second voltage. The second voltage is greater than or equal to the first voltage.

[0006] A power bus voltage lower than a first voltage indicates that the output power of the power conversion device is insufficient to meet the load's power requirements. In this case, the backup power module can discharge to the power bus. However, the backup power module's long response time can easily lead to power instability, affecting the normal operation of the load. Therefore, in this embodiment, when the power bus voltage is lower than the first voltage and the backup power module's output voltage is lower than the second voltage, a supercapacitor module discharges to the power bus. Based on this, the fast discharge speed of the supercapacitor can be used to promptly supply power to the operating load before the backup power module starts up and outputs a stable voltage. This helps stabilize the power bus voltage when fluctuations occur, thus better meeting the load's power requirements and improving the load's operational stability.

[0007] In one implementation, the supercapacitor module is further used to stop discharging to the power bus when the output voltage of the backup power module is greater than or equal to the second voltage.

[0008] When the output voltage of the backup power module is greater than or equal to the second voltage, it indicates that the backup power module is capable of outputting a voltage sufficient for stable load operation. Considering that supercapacitors are more expensive than lithium batteries, and that the energy storage capacity of a supercapacitor is significantly smaller than that of a lithium battery for the same volume, the supercapacitor module in this embodiment stops discharging to the power bus when the output voltage of the backup power module is greater than or equal to the second voltage. Based on this, the power loss of the supercapacitor module can be reduced, allowing for timely power supply to the operating load should the power bus voltage drop again during subsequent operation, thereby better meeting the load's power supply needs and improving the stability of load operation.

[0009] In one implementation, when the output voltage of the power conversion device is greater than the third voltage, the power conversion device charges the supercapacitor module and the backup power module via the power bus. The third voltage is greater than the second voltage.

[0010] When the output voltage of the power conversion device is greater than the third voltage, it indicates that the output voltage of the power conversion device can fully meet the power supply requirements of the load. At this time, the power conversion device can charge the supercapacitor module and the backup power module through the power bus to replenish the power of the supercapacitor module and the backup power module in a timely manner, so as to supply power to the load in a timely manner when the voltage of the power bus is lower than the first voltage again, thereby improving the stability of the load operation.

[0011] In one implementation, during periods when the output voltage of the power conversion device is greater than the third voltage and the electricity price on the grid is low, the power conversion device charges the supercapacitor module and the backup power module via the power bus.

[0012] When the input terminal of the power conversion device is electrically connected to the power grid and the output terminal is electrically connected to the power bus, a power conversion device output voltage greater than a third voltage indicates that the output voltage can fully meet the power supply requirements of the load. Simultaneously, electricity costs are lower during off-peak hours. Therefore, in this embodiment, when the output voltage of the power conversion device is greater than the third voltage and during off-peak hours, the power conversion device charges the supercapacitor module and the backup power module via the power bus. This replenishes the power of the supercapacitor module and the backup power module, reduces the charging cost of the supercapacitor, and thus lowers the power cost of the computing device. In one implementation, when the output voltage of the backup power module decreases from greater than or equal to the second voltage to less than the first voltage, the supercapacitor module discharges to the power bus.

[0013] Once the output voltage of the backup power module exceeds the second voltage, the load is powered through the backup power module. During power supply, if the output voltage of the backup power module decreases from greater than or equal to the second voltage to less than the first voltage, it indicates that the output power of the backup power module is no longer sufficient to meet the power supply requirements for stable load operation. At this point, the supercapacitor module discharges to the power bus, thereby ensuring that the load can continue to operate stably.

[0014] In one implementation, the computing device further includes a first control switch, and the output of the power conversion device is connected to the power bus through the first control switch; when the first control switch is off, the backup power module discharges to the power bus.

[0015] After the first control switch is turned off, the backup power module discharges to the power bus, which can ensure the stable operation of the load while avoiding the impact of external power supply on the stability of the computing device.

[0016] In one implementation, the first control switch is disconnected during peak electricity price periods in the power grid. Disconnection of the first control switch during peak electricity price periods allows for discharge to the power bus via the backup power module and the supercapacitor module, thereby reducing electricity costs.

[0017] In one implementation, the supercapacitor module includes a supercapacitor, a charging / discharging circuit, and a voltage regulator circuit. One end of the charging / discharging circuit is connected to the supercapacitor, and the other end is connected to one end of the voltage regulator circuit. The other end of the voltage regulator circuit is connected to a power bus. The charging / discharging circuit is used to discharge and charge the supercapacitor, and the voltage regulator circuit is used to regulate the voltage during the charging and discharging process of the supercapacitor.

[0018] By employing the above methods, the charging and discharging circuits and voltage regulation circuits in the supercapacitor module can make the voltage of the supercapacitor more stable during charging and discharging, thereby improving the stability of the power supply.

[0019] In one implementation, the supercapacitor module further includes a second control switch, one end of which is connected to the supercapacitor, and the second end of which is connected to the power bus via a voltage regulator circuit. When the second control switch is turned on, the supercapacitor also charges and discharges based on the voltage difference with the power bus.

[0020] In this way, the supercapacitor in the supercapacitor module can be directly connected to the power bus via a second control switch and a voltage regulator circuit. Therefore, when the charging / discharging circuit fails or the second control switch is turned on in a passive charging / discharging mode, the supercapacitor can be charged and discharged via the voltage difference between the power bus and the supercapacitor, improving the reliability of the computing device's power supply.

[0021] In one implementation, the computing device further includes a power interface module, which comprises multiple power interfaces. The power conversion device, supercapacitor module, and backup power module are connected to the power bus via power interfaces of the same type on the power interface module.

[0022] In the above implementation, the power conversion device, supercapacitor module, and backup power module are connected to the power bus via the same type of power interface on the power interface module. Based on this, the power conversion device, supercapacitor module, and backup power module can be mixed and matched on the power interface module, allowing for flexible adjustment of the configuration quantity of different modules according to the required power, load fluctuation range, and backup power time requirements.

[0032] Figure 1 A structural diagram of a data center provided for this application.

[0033] Please see Figure 1 This application provides a data center 10. The data center 10 is a globally collaborative network of specific devices used to transmit, accelerate, display, compute, and store data on the Internet network infrastructure.

[0034] The data center 10 may include multiple computing systems 11, and each computing system 11 may include a rack 200 and multiple computing devices 100, which may be arranged in the computer room.

[0035] The input terminal of a column head unit 200 can be connected to an AC line, and the output terminal of the column head unit 200 can be connected to the input terminals of multiple computing devices 100. The column head unit 200 can draw power from the AC line and distribute the power to the multiple computing devices 100 connected to it.

[0036] For example, the AC line can provide 220V AC power, and the AC line can be an electrical grid. The multiple computing devices 100 of the computing system 11 can be arranged in a row or distributed.

[0037] Figure 2 This is a schematic diagram of the structure of a computing device provided in an embodiment of this application.

[0038] Please see Figure 2 The computing device 100 may include a cabinet 300 and multiple computing nodes 400. The input terminals of the multiple computing nodes 400 are electrically connected to the output terminal of the power conversion device 110 via a power bus 120. The output terminal of the power conversion device 110 is electrically connected to the output terminal of the column cabinet 200. Thus, the computing nodes 400 can draw power from the column cabinet 200 through the power conversion device 110.

[0039] Multiple compute nodes 400 can be located within a rack 300, allowing the rack 300 to protect the compute nodes 400. Furthermore, multiple compute nodes 400 can be stacked within the same rack 300 to improve the space utilization of the data center 10 and reduce space costs.

[0040] In some examples, in addition to compute node 400, computing device 100 may also include loads such as storage node 141 and network node 142. The loads such as storage node 141 and network node 142 are connected in parallel to the power bus 120.

[0041] Furthermore, to improve the stability of power supply to the computing node 400 and other loads in the computing device 100, a supercapacitor module 150 and a backup power module 130 can also be provided in the computing device 100 for auxiliary power supply. The supercapacitor module 150 and the backup power module 130 are electrically connected to the power bus 120, that is, the supercapacitor module 150 and the backup power module 130 are connected in parallel to the power bus 120.

[0042] When the AC line load is low, the power conversion device 110 converts the AC power output from the row head cabinet 200 into DC power to supply power to the power bus 120. When the voltage of the power bus 120 is less than the first voltage, it indicates that the output power of the power conversion device 110 is insufficient to meet the power supply requirements of the computing node 400 and other loads. At this time, the backup power module 130 can discharge to the power bus 120 to ensure the stable operation of the computing node 400 and other loads. However, the backup power module 130 usually requires a long response time to output a voltage that meets the power supply requirements, i.e., the second voltage. Therefore, the supercapacitor module 150 of this application discharges to the power bus 120 when the voltage of the power bus 120 is less than the first voltage and the output voltage of the backup power module 130 is less than the second voltage. The second voltage is greater than or equal to the first voltage. For example, when the first voltage is 24V, the second voltage can be 24V or greater than 24V.

[0043] For example, the backup power module 130 may be a lithium battery module. The backup power module 130 serves as an auxiliary power source or a standby power source, and its voltage is lower than the voltage output by the power conversion device 110. Furthermore, the voltage difference between the backup power module 130 and the voltage output by the power conversion device 110 is sufficiently large (generally not less than 2V) so that the backup power module 130 can be in an unloaded state when the power conversion device 110 is able to supply power to the computing node 400 and other loads.

[0044] In the above implementation, the first voltage is the minimum voltage value required to ensure the normal operation of the computing node 400 and other loads in operation. When the voltage of the power bus 120 is greater than or equal to the first voltage, it indicates that the output power of the power conversion device 110 can meet the power supply requirements of the currently running computing node 400 and other loads. At this time, supplying power to the power bus 120 through the power conversion device 110 can ensure the stable operation of the currently running computing node 400 and other loads.

[0045] When the voltage on the power bus 120 is lower than the first voltage, it indicates that the output power of the power conversion device 110 is insufficient to meet the power supply requirements of the currently running computing node 400 and other loads. At this time, the backup power module 130 discharges to the power bus 120. However, the backup power module 130 requires a relatively long response time from startup to outputting a stable voltage. During this process, the supercapacitor module 150 discharges to the power bus 120, taking advantage of the fast discharge speed of the supercapacitor to promptly supply power to the running computing node 400 and other loads, thereby meeting the instantaneous power consumption requirements, better satisfying the power supply needs of the loads, and improving the stability of load operation.

[0046] In one implementation, the computing device 100 can be a rack-mount server. The computing node 400 can be a server unit within a rack server, a high-density server, or a blade server. When the computing node 400 is a server unit within a high-density server, the rack includes multiple high-density servers, and each high-density server can include several computing nodes. When the computing node 400 is a blade server, the rack is a blade server chassis.

[0047] In one implementation, the computing node 400 can be a hardware server. It can be used to provide services and is a server capable of establishing communication connections with other devices and providing computing and / or storage functions to those devices.

[0048] In one implementation, some computing nodes 400 in the computing device 100 are workstations, and some computing nodes 400 are servers.

[0049] In one implementation, network node 142 can be a switch, used to connect other network devices to communicate with other computing devices 100. It should be noted that a switch is one example of network node 142; this application uses a switch as an example to illustrate the computing device 100 provided in this application. It is worth noting that a switch does not constitute a specific limitation on a network node. In practical applications, other network nodes with similar functions to a switch can be used to implement communication functions, such as gateways and repeaters.

[0050] In one implementation, storage node 141 may include volatile memory (e.g., static random access memory, dynamic random access memory) and non-volatile memory (e.g., read-only memory, flash memory, magnetoresistive random access memory, etc.).

[0051] In other implementations, the computing device 100 may not include the cabinet 300, and the computing node 400, network node 142, and storage node 141 may be set on other carrier objects.

[0052] In one implementation, the computing node 400 includes, but is not limited to, a motherboard, a processor, volatile memory, a baseboard management controller (BMC), non-volatile memory, a network card, a power supply, a backplane connector, and a network port.

[0053] In one implementation, the power conversion device 110 has a power-down retention function. Specifically, the power conversion device 110 has a storage module (e.g., a capacitor) that enables it to continuously supply power to the computing node 400 and other loads even during a brief interruption of the AC line (e.g., a voltage dip within 20ms). The power conversion device 110 also has a power-down retention duration. The power-down retention duration refers to the longest duration for which the power conversion device 110 continues to supply power to the computing node 400 and other loads after the connection between the power conversion device 110 and the AC line is interrupted.

[0054] In one implementation, the supercapacitor module 150 is further configured to stop discharging to the power bus 120 when the output voltage of the backup power module 130 is greater than or equal to the second voltage.

[0055] When the output voltage of the backup power module 130 is greater than or equal to the second voltage, it indicates that the output power of the backup power module 130 is sufficient to meet the power supply requirements of the computing node 400 and other loads in operation. At this time, the supercapacitor module 150 stops discharging to the power bus 120, which reduces the power loss of the supercapacitor module 150, so that the supercapacitor module 150 can still ensure the stability of the computing node and other loads in the following process.

[0056] In one implementation, when the output voltage of the power conversion device 110 is greater than the third voltage, the power conversion device 110 charges the supercapacitor module 150 and the backup power module 130 via the power bus 120. The third voltage is greater than the second voltage and must also be greater than the voltages of the supercapacitor module 150 and the backup power module 130.

[0057] In one implementation, both the backup power module 130 and the supercapacitor module 150 are electrically connected to the controller 160 in the computing device 100. The backup power module 130 and the supercapacitor module 150 can be charged and discharged under the control of the controller 160 in the computing device 100. Specifically, when the voltage of the power bus is greater than a third voltage, the controller 160 can control the backup power module 130 and the supercapacitor module 150 to charge in order to maintain the power of the backup power module 130.

[0058] When an AC line fault occurs, the AC line load increases, or the number of computing nodes 400 or other loads operating in computing device 10 increases, the voltage of the power bus 120 will decrease. In this case, controller 160 controls backup power module 130 to discharge to ensure that computing nodes 400 or other loads can continue to operate normally. Specifically, when the voltage of the power bus 120 is less than a first voltage and the output voltage of backup power module 130 is less than a second voltage, controller 160 controls supercapacitor module 150 to discharge to the power bus.

[0059] For example, the voltage of the supercapacitor module 150 and the backup power module 130 is 26V, and the third voltage can also be 26V. When the voltage of the power bus 120 is greater than 26V (i.e., the output voltage of the power conversion device 110 is greater than 26V), the controller 160 controls the supercapacitor module 150 to charge, thereby replenishing the power of the supercapacitor module 150 in a timely manner. This ensures that the output power of the supercapacitor module 150 can meet the power supply requirements for the stable operation of the computing node 400 and other loads when the computing node 400 and other loads increase or when there is an AC line fault during subsequent operation.

[0060] In the above implementation, the controller 160 includes, but is not limited to, a central processing unit (CPU), a network processing unit (NPU), a graphics processing unit (GPU), a digital signal processor (DSP), or a general-purpose processor.

[0061] Figure 3 A schematic diagram of another computing device provided in this application.

[0062] In one implementation, such as Figure 3 As shown, the supercapacitor module 150 includes a supercapacitor 151, a charging / discharging circuit 152, and a voltage regulator circuit 153. One end of the charging / discharging circuit 152 is connected to the supercapacitor 151, and the other end of the charging / discharging circuit 152 is connected to one end of the voltage regulator circuit 153. The other end of the voltage regulator circuit 153 is connected to the power bus 120. The charging / discharging circuit 152 is used to discharge and charge the supercapacitor 151, and the voltage regulator circuit 153 is used to regulate the voltage during the charging and discharging processes of the supercapacitor 151.

[0063] In one implementation, the charging / discharging circuit 152 is connected to the controller 160. The controller 160 is also electrically connected to the power bus 120 to supply power to the controller 160. The controller 160 controls the charging / discharging circuit 152 to discharge and charge the supercapacitor 151. The voltage regulator circuit 153 is used to regulate the voltage during the charging and discharging of the supercapacitor 151. Specifically, when the supercapacitor 151 is discharging, the voltage regulator circuit 153 regulates the DC power output from the supercapacitor 151 and outputs it to the power bus 120. When the supercapacitor 151 is charging, the voltage regulator circuit 153 regulates the DC power from the power bus 120 and charges the supercapacitor 151.

[0064] For example, when the voltage of the power bus 120 is less than the first voltage and the output voltage of the backup power module 130 is less than the second voltage, the controller 160 controls the charging and discharging circuit 152 to discharge the supercapacitor 151, thereby utilizing the fast discharge speed of the supercapacitor 151 to meet the instantaneous power consumption requirements of the computing node 400 and other loads. When the output voltage of the power conversion device 110 is greater than the third voltage, the voltage of the power bus 120 is greater than the third voltage, and the controller 160 controls the charging and discharging circuit 152 to charge the supercapacitor 151, thereby replenishing the power of the supercapacitor 151 in a timely manner. This ensures that when the computing node 400 and other loads increase, the AC line load increases, or an AC line fault occurs during subsequent operation, the output power of the supercapacitor module 150 can meet the power supply requirements for the stable operation of the computing node 400 and other loads.

[0065] In one implementation, the computing device 10 may further include a voltage detection circuit connected to the controller 160, which is used to detect the voltage of the power bus 120, the output voltage of the power conversion device 110, the output voltage of the supercapacitor module 150, and the output voltage of the backup power module 130.

[0066] Based on this, the controller 160 can directly obtain the voltage of each power supply module and the power bus through the voltage detection circuit, thereby reducing the total response time of the control process.

[0067] For example, the voltage detection circuit described above may include multiple voltage divider circuits. Each voltage divider circuit is used to detect the voltage of one module.

[0068] Considering that electricity prices vary at different times of day, for example, daytime is typically peak electricity consumption period, and the grid electricity price is at its peak. At this time, while charging the supercapacitor module 150 when the voltage of the power bus 120 is higher than the second voltage can replenish the supercapacitor module 150's energy, the electricity cost is high. At night, which is typically off-peak electricity consumption period, the corresponding grid electricity price is at its low. At this time, charging the supercapacitor module 150 when the voltage of the power bus 120 is higher than the third voltage can both replenish the supercapacitor module 150's energy and reduce costs.

[0069] Therefore, in order to reduce electricity costs, in one implementation, during periods when the voltage of the power bus 120 is greater than the third voltage and the electricity price of the grid is low, the power conversion device 110 charges the supercapacitor module 150 and the backup power module 130 through the power bus 120.

[0070] For example, when the peak electricity price period is from 8:00 to 22:00 and the off-peak period is from 22:00 to 8:00 the next day, the controller 160 does not need to control the charging of the supercapacitor module 150 and the backup power module 130 when the voltage of the power bus 120 is greater than the third voltage between 8:00 and 22:00. Instead, it controls the charging of the supercapacitor module 150 and the backup power module 130 when the voltage of the power bus 120 is greater than the third voltage between 8:00 and 22:00.

[0071] For example, when the peak electricity price period is 9:00 to 11:30, 14:00 to 16:30, and 19:00 to 21:00, and the off-peak electricity price period is 23:00 to 7:00 the next day, the controller 160 does not need to control the supercapacitor module 150 and the backup power module 130 to charge when the voltage of the power bus 120 is greater than the third voltage during the periods of 9:00 to 11:30, 14:00 to 16:30, and 19:00 to 21:00. However, when the voltage of the power bus 120 is greater than the third voltage during the period of 23:00 to 7:00 the next day, the controller controls the supercapacitor module 150 and the backup power module 130 to charge.

[0072] It should be understood that the above-described method of dividing peak and off-peak electricity price periods is merely an exemplary scheme provided in this application. Specific methods for dividing peak and off-peak electricity price periods can be set according to the regional classification standards of the location of the computing device 10.

[0073] In one implementation, when the output voltage of the backup power module 130 decreases from greater than or equal to the second voltage to less than the first voltage, the supercapacitor module 150 discharges to the power bus 120.

[0074] For example, when the output voltage of the backup power module 130 is greater than the second voltage, and the voltage of the power bus 120 decreases again to less than the first voltage, the controller 160 controls the supercapacitor module 150 to discharge to the power bus 120.

[0075] In one implementation, considering that the supercapacitor module 150 has the advantages of fast discharge speed and short response time, and the backup power module 130 has the advantage of large energy storage capacity, the advantages of the supercapacitor module 150 and the backup power module 130 can be fully utilized to perform combined control of the supercapacitor module 150 and the backup power module 130.

[0076] In one implementation, when the backup power module 130 and the supercapacitor module 150 discharge to the power bus 120, the controller 160 is further configured to: control the supercapacitor module 150 to stop discharging to the power bus 120 when the duration of the discharge from the supercapacitor module 150 to the power bus 120 exceeds a duration threshold.

[0077] In the above implementation, the aforementioned duration threshold is the response time from the start of operation of the backup power module 130 to a stable output. When the duration of the discharge from the supercapacitor module 150 to the power bus 120 exceeds the duration threshold, the backup power module 130 is already able to output a stable voltage normally. At this time, the controller 160 controls the supercapacitor module 150 to stop discharging to the power bus 120, which reduces the electrical energy released by the supercapacitor module 150, so that the power supply requirements of the computing node 400 and other loads can still be met during subsequent use.

[0078] In one example, the backup power module 130 has a response time of 10ms from the start of operation to the stable output. When the voltage of the power bus 120 is less than the first voltage, the controller 160 controls both the backup power module 130 and the supercapacitor module 150 to discharge to the power bus 120. When the duration of the supercapacitor module 150 discharging to the power bus 120 is greater than 10ms, the controller 160 controls the supercapacitor module 150 to stop discharging to the power bus 120.

[0079] In another example, the backup power module 130 has a response time of 5ms from the start of operation to the stable output. When the voltage of the power bus 120 is less than the first voltage, the controller 160 controls both the backup power module 130 and the supercapacitor module 150 to discharge to the power bus 120. When the duration of the supercapacitor module 150 discharging to the power bus 120 is greater than 5ms, the controller 160 controls the supercapacitor module 150 to stop discharging to the power bus 120.

[0080] It should be understood that the aforementioned duration thresholds are merely exemplary methods provided by this application for the purpose of facilitating understanding of the solution presented herein. The aforementioned duration thresholds can be set according to the actual duration of the backup power module 130 used in each computing device 10 from the start of operation of the backup power module 130 controlled by the controller 160 until the backup power module 130 outputs a stable value; no specific limitations are imposed here.

[0081] In one implementation, when the controller 160 controls both the backup power module 130 and the supercapacitor module 150 to discharge to the power bus 120, and the output voltage of the supercapacitor module 150 is less than or equal to a fourth voltage while the controller 160 controls the supercapacitor module 150 to stop discharging to the power bus 120. The aforementioned fourth voltage can be the voltage value of the supercapacitor module 150 after its output has decreased from the start of operation of the backup power module 130 to a stable output.

[0082] For example, the voltage value of the supercapacitor module 150 when discharging to the power bus 120 is 26V. The fourth voltage can be the voltage value of the supercapacitor module 150 after the output voltage of the backup power module 130 decreases from the start of operation to the stable output, which is 24V. Then, when the output voltage of the supercapacitor module 150 is less than or equal to 24V, the controller 160 controls the supercapacitor module 150 to stop discharging to the power bus 120.

[0083] It should be understood that the aforementioned fourth voltage value is merely an exemplary voltage value provided for the purpose of understanding the power supply method of this application. In specific implementation, the aforementioned fourth voltage can be set according to the voltage value of the supercapacitor module 150 after the backup power module 130 in the computing device 10 has reduced from the start of operation to the point where the output is stable. This application does not impose any specific limitations on this.

[0084] In some scenarios, when the AC line fails, the computing node 400 and other loads increase rapidly, or the AC line load increases, the computing device 100 needs to run for a long time to avoid sudden service interruption affecting service processing efficiency.

[0085] In one implementation, when the voltage of the power bus 120 is less than the first voltage, during the process of the controller 160 controlling the backup power module 130 to discharge to the power bus 120, the controller 160 is further configured to: when controlling the supercapacitor module 150 to discharge to the power bus 120, when the output voltage of the supercapacitor module 150 is less than the fourth voltage, control the backup power module 130 to discharge to the power bus 120.

[0086] In this way, when the number of running computing nodes 400 and other loads increases, or when there is an AC line fault or an increased load on the AC line, the controller 160 controls the supercapacitor module 150 to discharge to the power bus 120 first, and the output voltage of the supercapacitor module 150 is less than the fourth voltage to control the backup power module 130 to discharge to the power bus 120. This allows the supercapacitor module 150 and the backup power module 130 to provide auxiliary power to the running computing nodes 400 and other loads for a longer period of time while meeting the power supply requirements of the running computing nodes 400 and other loads. This provides a longer response time for restoring the power supply of the power conversion device 110 when the power conversion device 110 cannot provide stable power.

[0087] In one implementation, the voltage of the supercapacitor module 150 can also be lower than the voltage of the backup power module 130. Based on this, the controller 160 can control the supercapacitor module 150 to charge while controlling the backup power module 130 to discharge to the power bus 120.

[0088] In one implementation, the input terminal of the power conversion device 110 can also be connected to a generator. When the generator is started due to an AC line fault, the controller 160 can also control the backup power module 130 and the supercapacitor module 150 to stop discharging to the power bus 120 after the voltage at the output terminal of the power conversion device 110 is greater than the second voltage, and control the backup power module 130 and the supercapacitor module 150 to charge when the voltage at the power bus 120 is greater than or equal to the third voltage.

[0089] Figure 4 This application provides a schematic diagram of the structure of another computing device.

[0090] like Figure 4 As shown, in one implementation, the computing device 100 provided in this application may further include a first control switch 170. The output terminal of the power conversion device 110 is electrically connected to one end of the first control switch 170, and the other end of the first control switch 170 is electrically connected to the power bus 120. The control terminal of the first control switch 170 is connected to a controller 160. The controller 160 can control the first control switch 170 to disconnect during peak electricity price periods or when there is a fault in the AC line connected to the input terminal of the power conversion device 110. When the first control switch 170 is disconnected, the backup power module 130 discharges to the power bus 120. The backup power module 130 can discharge to the power bus 120 under the control of the controller 160.

[0091] During peak electricity price periods, using AC power via power conversion device 110 to supply power to multiple computing nodes 400, storage nodes 141, network nodes 142, etc., in computing device 10 increases electricity costs. This application also includes a first control switch 170 between the output of power conversion device 110 and power bus 120. During peak electricity price periods, controller 160 can control the first control switch 170 to open and control the backup power module 130 to discharge.

[0092] Based on this, during peak electricity price periods, the computing nodes 400 and other loads in the computing device 10 can be powered by the backup power module 130, thereby making full use of the electrical energy stored in the backup power module 130 to reduce electricity costs. In addition, when the power supply connected to the input terminal of the power conversion device 110 fails, the first control switch 170 can be disconnected to avoid affecting the stability of the operation of the computing device 10.

[0093] In the above implementation, the first control switch 170 can be any one of a relay, a transistor, a metal oxide semiconductor field effect transistor (MOS transistor), or an insulated gate bipolar transistor (IGBT), and this application does not impose any specific restrictions on it.

[0094] In one implementation, it is still as follows Figure 4 As shown, the supercapacitor module 150 also includes a second control switch 154. One end of the second control switch 154 is connected to the supercapacitor 151, and the second end of the second control switch 154 is connected to the power bus 120 through the voltage regulator circuit 153. That is, the second control switch 154 is connected in parallel with the charging and discharging circuit 152.

[0095] In this manner, the supercapacitor 151 in the supercapacitor module 150 can be directly connected to the power bus 120 via the second control switch 154. Therefore, when the charging / discharging circuit 152 fails, the controller 160 can also control the second control switch 154 to turn on, thereby enabling the supercapacitor 151 to charge and discharge via the voltage difference between the power bus 120 and the supercapacitor 151, improving the reliability of the power supply to the computing device 100. Specifically, when the controller 160 controls the second control switch 154 to turn on, the supercapacitor 151 can be charged when the voltage of the power bus 120 is higher than the voltage of the supercapacitor 151. Conversely, the supercapacitor 151 can be discharged when the voltage of the power bus 120 is lower than the voltage of the supercapacitor 151.

[0096] During the actual operation of the computing device 10, when the charging and discharging circuit 152 is functioning normally, the controller 160 can also actively control the second control switch 154 to turn on according to the actual configured program. This allows the supercapacitor 151 to passively charge and discharge based on the voltage difference between it and the power bus 120, reducing the impact of the impedance of the charging and discharging circuit 152 on the charging and discharging efficiency of the supercapacitor 151. Specifically, when the voltage of the power bus 120 is higher than the voltage of the supercapacitor 151, the supercapacitor 151 charges. When the voltage of the power bus 120 is lower than the voltage of the supercapacitor 151, the supercapacitor 151 discharges.

[0097] In the above implementation, the second control switch 154 can be any one of a relay, a transistor, a metal oxide semiconductor field effect transistor (MOS transistor), or an insulated gate bipolar transistor (IGBT), and this application does not impose any specific restrictions on it.

[0098] In one implementation, the computing device 100 may further include a power interface module. This power interface module includes multiple power interfaces. The backup power module 130, the power conversion device 110, and the supercapacitor module 150 can be connected to the power bus 120 using the same type of power interfaces on the power interface module in the computing device 10.

[0099] Therefore, when the power bus 120 is connected to multiple backup power modules 130, multiple power conversion devices 110, and multiple supercapacitor modules 150, since the backup power modules 130, power conversion devices 110, and supercapacitor modules 150 have the same interface type, the backup power modules 130, power conversion devices 110, and supercapacitor modules 150 can be mixed and matched through the interfaces on the circuit board, which improves the convenience of the installation process.

[0100] In summary, the power bus 120 in the computing device 10 provided in this application is powered by the power conversion device 110. Furthermore, before the voltage of the power bus 120 is lower than the minimum voltage required for the normal operation of the computing node 400 and other loads, and before the output voltage of the backup power module meets the power supply requirements of the computing node 400 and other loads, the supercapacitor module 150 can quickly discharge to the power bus 120. This better meets the instantaneous power consumption requirements of the computing device 10, improves the stability of the operation of the computing device 10, and avoids the impact on the business processing of the computing device 10 due to AC line failures, a rapid increase in the number of computing nodes 400 and other loads, or an increase in the load on the AC line.
