[0062] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application are further described in detail below in combination with the embodiments and with reference to the accompanying drawings.

[0063] It should be noted that all expressions using "first" and "second" in the embodiments of this application are for the purpose of distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of this application. Subsequent embodiments will not explain this one by one.

[0064] As shown in Figure 2, each functional circuit in a related art power supply is soldered directly onto the power supply motherboard according to the layout. Therefore, any problem with the power supply requires replacement of the entire power supply, including each functional circuit and the power supply motherboard. Furthermore, an abnormality in one functional circuit within the power supply can cause failure in other functional circuits, making it difficult to determine the cause of the abnormality, increasing maintenance costs and reducing maintenance efficiency.

[0065] Based on the above objectives, the first aspect of the embodiments of the present application provides an embodiment of a power supply. As shown in FIG1 , the power supply 1 includes a power supply mainboard 10 , a plurality of circuit modules 20 and a digital management chip 30 .

[0066] The power supply motherboard 10 has several connector slots. Each circuit module 20 is connected to the power supply motherboard 10 via its corresponding connector slot. Each circuit module 20 includes a corresponding detection device 21, which is configured to issue an abnormality signal upon detecting an abnormality in the corresponding circuit module. A digital management chip 30 is connected to the power supply motherboard 10. Upon receiving an abnormality signal from a detection device 21, the digital management chip 30 is configured to identify the circuit module 20 corresponding to the detection device 21 that issued the abnormality signal as a faulty circuit module and to transmit fault information about the faulty circuit module, instructing the system to replace the faulty circuit module in the connector slot corresponding to the faulty circuit module.

[0067] In some embodiments, the detection device 21 includes a temperature sensor, which can perform voltage division sampling on the circuit module 20 through a thermistor, and determine whether an abnormality occurs in the circuit module 20 by detecting the temperature of the circuit module 20. In some embodiments, the detection device 21 includes a current sensor or a current transformer for detecting the current of the circuit module 20. In some embodiments, the detection device 21 includes a voltage sensor, which can perform resistance voltage division sampling on the circuit module 20, and determine whether an abnormality occurs by detecting the voltage of the circuit module 20. The sampled parameters such as temperature, current and voltage are transmitted to the digital management chip for processing. The digital management chip can obtain the power of the circuit module 20 by multiplying the sampled voltage and current. By real-time monitoring of the sampled or calculated parameters such as temperature, voltage, current, power, etc., if the abnormal threshold value set by the digital management chip is exceeded, the digital management chip can determine that the circuit module 20 is abnormal.

[0068] Through the power supply proposed in this application, a set of standard power supply motherboards and line modules are designed. First, multiple connector slots are designed on the power supply motherboard, and the line unit is designed as an independent module, so as to achieve the purpose of obtaining a power supply that meets different power requirements by inserting line modules of different levels or different numbers into the connector slots of the same power supply motherboard, thereby improving the compatibility and versatility of the line unit. In addition, each line module has a detection device. As long as an abnormality occurs in a single line module, the detection device will immediately disconnect the line module from the power supply motherboard, ensuring that the power supply motherboard and other line modules are not affected by the abnormal situation. Furthermore, a digital management chip is added to the power supply motherboard, which can monitor the working parameters or connection status of each line module in real time, and can record the abnormal information of each line module at any time to send the abnormal information to the management system, and promptly instruct to replace the line module in the connector slot where the abnormal situation occurs, thereby avoiding the replacement of the entire power supply. Only the line module with the abnormality needs to be replaced, thereby improving the overall maintainability of the power supply and saving maintenance efficiency and cost.

[0069] In some embodiments, the digital management chip is further configured to: monitor, through corresponding detection devices, whether each line module is successfully inserted into the corresponding connector slot and / or whether the working parameters of each line module are normal; in response to a line module not being successfully inserted into the corresponding connector slot and / or a line module having abnormal working parameters, send the position information of the target line module to instruct adjustment of the target line module, wherein the target line module is a line module that is not successfully inserted into the corresponding connector slot and / or has abnormal working parameters; cut off the power supply and routing signals of the target line module in the power supply motherboard.

[0070] A power supply proposed in this application manages and monitors the line module by setting a digital management chip on the power supply mainboard. In the event of failure or abnormality, the location information of the faulty line unit can be quickly located, and the user can be promptly informed to replace the faulty line unit in the corresponding connector slot, thereby improving the efficiency of power supply fault troubleshooting and ensuring normal power supply.

[0071] In some embodiments, the line module includes a main power line module and a non-main power line module, the main power line module corresponds to at least two connector slots, and the non-main power line module corresponds to one connector slot.

[0072] In some embodiments, the main power circuit module includes several circuit modules corresponding to main power functional circuit categories, and the main power functional circuit categories include power factor correction circuits, synchronous rectification circuits, and auxiliary circuits.

[0073] In some embodiments, the non-main power circuit module includes several circuit modules corresponding to non-main power functional circuit categories, and the non-main power functional circuit categories include input fan circuits, electromagnetic interference rectification circuits, and logic gate circuits.

[0074] In some embodiments, the main power circuit module corresponds to the primary functional circuit within the power supply. It also houses the largest number of power devices and is most susceptible to abnormalities. The main power circuit module primarily includes a PFC (Power Factor Correction) circuit module, a DC-DC + SR (Synchronous Rectification) circuit module, and an AUX (Auxiliary) circuit module. N+M module redundancy is implemented for the main power circuit module, where N and M are positive integers. For example, a 1+1 redundancy scheme can be employed within the PFC circuit module. Under normal operating conditions, both PFC circuit modules can operate simultaneously. When an abnormality occurs in PFC circuit module 1, the digital management chip proactively disconnects the power supply and corresponding power routing signals to isolate PFC circuit module 1. However, because PFC circuit module 2 remains operational, the abnormality of PFC circuit module 1 does not affect the overall operation of the power supply. Therefore, the power supply motherboard can have multiple connector slots for the same main power module model to connect multiple main power circuit modules of the same model. Similarly, 1+2 redundant modules can be used for the main power line module, and N+M module redundancy can be designed according to actual application conditions. The number of N+M module redundancy is not limited here.

[0075] In some embodiments, for non-main power line modules, since the failure probability is low, redundant design is not required from the perspective of design layout and cost, and therefore, there is a one-to-one correspondence between the non-main power line modules and the connector slots.

[0076] In some embodiments, the digital management chip is further configured to: obtain the power demand of the power supply, and determine whether the power demand of the power supply exceeds the main power threshold; in response to the power demand of the power supply not exceeding the main power threshold, instruct to insert a main power line module into the connector slot corresponding to the power supply mainboard; in response to the power demand of the power supply exceeding the main power threshold, instruct to insert at least two main power line modules into the connector slot corresponding to the power supply mainboard.

[0077] FIG3 is a layout perspective diagram of an embodiment of a power supply mainboard and circuit module structures provided in the present application.

[0078] In one example, taking a CRPS (Common Redundant Power Supply, standard architecture server power supply) standard power supply with a size of 185mm*73.5mm*40mm as an example, when the power supply motherboard has been fixed, corresponding connector slots are reserved on the power supply motherboard for each functional line. Because the PFC line, DC-DC+SR line and AUC line are the main power lines in the power supply, the power supply motherboard needs to reserve at least 2 connector slots for the PFC line, DC-DC+SR line and AUC line parts. For example, 2-3 connector slots can be reserved to perform N+M module redundancy for the main power line module, as shown in Figure 3.

[0079] A power supply proposed in this application sets a reserved connector slot on the power supply mainboard, and the modular line unit is matched with the connector slot of the power supply mainboard to achieve flexible replacement of each power supply line, which is convenient for timely maintenance of the power supply. In addition, multiple connector slots are reserved for the main power line module to enable redundancy and expansion of the main power line module according to different power requirements.

[0080] In some embodiments, the digital management chip is further configured to: obtain power requirements, and according to the power requirements, instruct to insert a non-main power line module whose power level matches the power requirements into the connector slot corresponding to the power mainboard.

[0081] Figure 4 is a schematic diagram of an embodiment of each circuit module inside the power supply provided by the present application. As shown in Figure 4, circuit modules with power levels corresponding to different performance requirements are set for different functional circuits. Circuit module A corresponds to the input line and the fan line. The input line in circuit module A supports C14 plug power cord and C20 plug power cord, and the fan supports a fan speed of 18,000 to 35,000 rpm. Among them, the C14 plug power cord is generally used to connect computers, various household appliances and office equipment, etc. The C20 plug power cord can output higher power and is more suitable for use in large servers, workstations and PDU (Power Distribution Unit) sockets and other fields. Circuit module B corresponds to EMI (Electromagnetic Interference) line or rectifier line. Line module B supports Class A (industrial grade) and Class B (civilian grade). Line module C corresponds to the auxiliary Standby output line. Line module C supports auxiliary output requirements of 10W-60W and is a low-power circuit module. Line module D corresponds to the PFC circuit, including traditional APFC (Active Power Factor Correction) circuits, bridgeless PFC circuits, and totem PFC circuits. Line module D can support power requirements of 800-2000W at high input voltages. Line module E corresponds to the DC-DC-SR circuit and can support power requirements of 800-1800W at high input voltages. Line module F corresponds to the ORing (logic gate) circuit. Among them, line modules A, B, and F are non-main power circuit modules, while line modules C, D, and E are main power circuit modules.

[0082] In one example, line module A and line module A2 are non-power main line modules corresponding to the same functional lines with different power levels. For example, the power level of line module A is that the input line supports C14 or the fan speed supports 18000, and the power level of line module A2 is that the input line supports C20 or the fan speed supports 35000. Similarly, line modules B and B2, line modules C and C2, and line modules F and F2 are also non-main power line modules corresponding to the same functional lines with different power levels, and line modules D, D1 and D2, and line modules E, E1 and E2 are main power line modules corresponding to the same functional lines with different power levels, as shown in Figure 4. Furthermore, according to power requirements, two or more main power line modules with the same power level can be selected for redundancy, or two or more main power line modules with different power levels can be selected for redundancy.

[0083] In one example, if there is a power demand of 800W, it is only necessary to insert a line module with the corresponding function and power level into the connector slot corresponding to each functional line on the power mainboard, as shown in Power Supply 1 in Figure 4. If there is a power demand of 2400W, then a non-main power line module with the corresponding function and power level is inserted into the connector slot corresponding to the non-main power functional line on the power mainboard, and two main power line modules with corresponding functions are inserted into the connector slot corresponding to the main power functional line, that is, two PFC line modules supporting 800-2000W and two DC-DC+SR line modules supporting 800-1800W are inserted to match the power demand of 2400W, as shown in Power Supply 2 in Figure 4. It should be noted that the power levels involved in this embodiment are only for illustration and should not be understood as limiting the solution of this application. During implementation, the design of the power level can be flexibly set according to the business scenario.

[0084] Through the power supply proposed in this application, after the required power demand is determined, it is only necessary to insert a line module of corresponding level and function into the power supply mainboard to obtain a power supply that meets the demand. There is no need to design independent power supplies for different power requirements or performance. Furthermore, all functional lines are modularized, and line modules with corresponding power levels are provided for different power requirements, which effectively improves the compatibility and versatility of the line unit. It is only necessary to combine or replace the line modules to achieve the purpose of being able to use line modules with the same functional lines in different power supplies, thereby improving the flexibility of power supply changes and facilitating the later maintenance of the power supply.

[0085] In some embodiments, the operating parameters include operating voltage, operating current, operating power, and operating temperature.

[0086] In some embodiments, a digital management chip transmits routing signals and provides power to each circuit module via a control circuit. A detection device acquires real-time operating parameters such as the operating voltage, operating current, operating power, and operating temperature of the corresponding circuit module. If any operating parameter falls outside the normal operating range corresponding to the power supply power requirement, the detection device issues an abnormality signal via the control circuit. The digital management chip senses the abnormality signal via the control circuit and immediately triggers a drive signal to shut off the power switch corresponding to the abnormal circuit module, thereby disconnecting the control circuit of the faulty circuit module from the power supply mainboard. Simultaneously with sensing the abnormality signal, the detection device acquires the operating parameters of the corresponding circuit module in order to analyze the corresponding abnormal state, such as if the voltage falls below the normal operating range or the temperature rises above the normal operating range. The detection device then reports the location and abnormal state of the circuit module to the BMC to which the power supply is connected, allowing a user to determine the cause and location of the power supply failure based on the reported abnormal state.

[0087] In some embodiments, each line module includes an independent fuse for disconnecting it from the power supply motherboard in the event of a line module failure.

[0088] In one embodiment, the protective device can be a fuse. Each circuit unit is designed with an independent fuse. As long as a single circuit module fails due to a short circuit, the fuse can be immediately disconnected without causing failure of the power supply motherboard and other circuit modules.

[0089] In some embodiments, if a power device in a circuit module shorts, causing instantaneous failure, a fuse can promptly sense the temperature change caused by the short circuit and trigger a fuse to disconnect the circuit module from the power supply motherboard. This ensures that the short circuit in the circuit module does not affect other circuit modules in the power supply, preventing them from failing. The digital management chip, combined with independent fuses within each circuit module, achieves dual protection for the power supply.

[0090] Through the power supply proposed in this application, a set of standard power supply motherboards and line modules are designed. First, multiple connector slots are designed on the power supply motherboard, and the line unit is designed as an independent module, so that by inserting line modules of different levels or different numbers into the connector slots of the power supply motherboard, a power supply that meets different power requirements can be obtained, effectively improving the compatibility and versatility of the line unit, and each line module has a detection device. When any individual line module has an abnormality, the detection device will immediately disconnect the abnormal line module from the power supply motherboard, ensuring that the power supply motherboard and other line modules are not affected by the abnormal situation. Further, a digital management chip is added to the power supply motherboard, which can monitor the working parameters or connection status of each line module in real time, and can record the abnormal information of each line module at any time to send the abnormal information to the management system, and promptly instruct to replace the line module in the connector slot where the abnormal situation occurs, avoiding the replacement of the entire power supply. Only the abnormal line module needs to be replaced, improving the overall maintainability of the power supply and saving maintenance efficiency and cost.

[0091] As shown in FIG5 , another aspect of the present application further provides a method for managing power supply abnormalities, the method comprising:

[0092] Step S1: Detecting whether a corresponding circuit module is abnormal by using a detection device, wherein a plurality of circuit modules are plugged into a plurality of connector slots of a power supply mainboard.

[0093] Step S2: In response to detecting that an abnormality occurs in the corresponding line module, triggering the detection device to send an abnormality signal.

[0094] Step S3: In response to the digital management chip receiving the abnormal signal sent by the detection device, the line module corresponding to the detection device that sent the abnormal signal is regarded as a faulty line module.

[0095] Step S4: The digital management chip sends fault information of the faulty line module to instruct the replacement of the faulty line module in the connector slot corresponding to the faulty line module.

[0096] FIG6 is a schematic diagram of an embodiment of a power supply abnormality management process provided in the present application.

[0097] In one example, the PFC circuit is used as an example to illustrate the power supply's abnormality management process. Since the PFC circuit is the power supply's primary power function circuit, two to three connector slots corresponding to PFC circuit modules are reserved on the power supply motherboard to facilitate module redundancy and power expansion. As shown in Figure 6, when the power supply is operating normally, the PFC1 and PFC2 circuit modules operate in parallel without interfering with each other. The digital management chip on the power supply motherboard monitors, via paths S1 and S2, whether the corresponding PFC1 and PFC2 circuit modules are successfully inserted into the connector slots and / or whether their operating parameters are abnormal. If an abnormality occurs in the PFC1 circuit module, the digital management chip detects it via path S1 and immediately triggers the DRV1 (drive) signal to shut down power switch Q1, disconnecting the PFC1 circuit module's control circuit from the power supply motherboard. If a power device short-circuit in the PFC1 circuit module causes a transient failure, since the power supply motherboard's control circuit cannot be disconnected quickly, a fuse is used to directly disconnect the PFC1 circuit module, preventing PFC1 from affecting other circuit modules. Because the PFC2 line module is still working normally, the power supply does not shut down at this time and continues to provide stable power supply. At this time, the digital management chip has recorded the fault information of the PFC1 line module and reported this fault information to the BMC (Baseboard Management Controller) system.

[0098] Furthermore, because the power supply continued to operate, the BMC system forwarded the fault information to the computer room operation and maintenance system. When the PFC2 line module also experienced an abnormality, its control circuit and the power supply mainboard were similarly disconnected, preventing the other line modules from failing due to the PFC circuit failure. Both PFC lines failed, causing the power supply to shut down. The digital management chip then reported the PFC2 line module's fault information to the BMC system, which then forwarded the fault information to the computer room operation and maintenance system, instructing maintenance personnel to locate the fault based on the location information in the fault information and replace the power supply's PFC line module.

[0099] The power supply abnormality management method proposed in this application improves the accuracy of locating power supply failure problems and the maintenance efficiency of computer room operation and maintenance personnel, and also saves the cost of replacing power supplies.

[0100] In some embodiments, the step of prompting to replace the faulty line module in the connector slot corresponding to the faulty line module includes: in response to the faulty line module being the main power line module and there being a target line module of the same model as the faulty line module in the power supply mainboard, judging whether the working parameters of the target line module are normal; in response to determining that the working parameters of the target line module are normal, the digital management chip sends a drive signal to cut off the power supply and routing signals between the faulty line module and the power supply mainboard, and maintains normal operation of the power supply through the target line module; determining the connector slot corresponding to the faulty line module according to the fault information, and instructing to replace the faulty line module in the corresponding connector slot.

[0101] In some embodiments, the abnormal management method of the power supply of the present application also includes: in response to the faulty line module being a non-main power line module, or in response to the faulty line module being a main power line module and there being no target line module of the same model as the faulty line module in the power supply mainboard, determining the connector slot corresponding to the faulty line module according to the fault information, and instructing to remove the faulty line module in the corresponding connector slot; in response to the faulty line module being removed, instructing to reinsert a line module with the same power level as the faulty line module in the corresponding connector slot so that the power supply continues to operate.

[0102] In some embodiments, the power supply abnormality management method of the present application also includes: the digital management chip monitors whether each line module is successfully inserted into the corresponding connector slot and / or whether the working parameters of several line modules are normal through a detection device; in response to the existence of a line module that is not successfully inserted into the corresponding connector slot and / or the existence of abnormal working parameters of the line module, the position information of the target line module is sent to indicate adjustment of the target line module, wherein the target line module is a line module that is not successfully inserted into the corresponding connector slot and / or has abnormal working parameters; and the power supply and routing signals of the target line module are cut off.
