[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on September 12, 2023, with application number 202311173223.3, and application name "Mainboard power supply circuit, power supply health management method, electronic device and storage medium", all contents of which are incorporated by reference in this application. Technical Field

[0003] The present application belongs to the field of computer technology, and in particular relates to a motherboard power supply circuit, a power supply health management method, an electronic device, and a storage medium. Background Art

[0004] The motherboard's power supply circuit is the most critical component of any computer. Its reliability determines the performance and lifespan of the computer. Power failures are a major cause of computer failures.

[0005] In related technologies, redundant power supply backup is provided by duplicating the functionality of power modules within the motherboard's power circuitry, preventing a single power failure from causing the entire computer to fail. For example, powering the central processing unit (CPU) can be provided by switching between two identical redundant power modules.

[0006] However, the power supply voltages required by components on the motherboard vary. If power modules with different output voltages are all backed up for power redundancy by duplicating their functions, there will be a large number of circuit elements and a large circuit area overhead, leading to high costs for the motherboard power supply circuit.

DETAILED DESCRIPTION

[0092] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0093] FIG1 is one of the circuit structure diagrams of a motherboard power supply circuit provided in an embodiment of the present application. As shown in FIG1 , the motherboard power supply circuit 10 includes: a control module 101, a plurality of first power modules 102, a second power module 103, and a first switch module 104;

[0094] The first power module 102 includes: a detection component 1021 and a first output terminal 1022, the detection component 1021 is used to detect the power health status of the first power module 102;

[0095] The control module 101 is electrically connected to the second power module 103, the detection components 1021 of each of the plurality of first power modules 102, and the first switch module 104, and is configured to generate a voltage control signal and a switching control signal based on a target detection result. The target detection result is sent by the detection component 1021 of the target first power module 102 and is configured to indicate that the target first power module 102 has a failure risk.

[0096] The first switch module 104 is electrically connected to the second power module 103 and the first output terminals 1022 of each of the plurality of first power modules 102, and is configured to connect the second power module 103 to the first output terminal 1022 of the target first power module 102 under the control of the switching control signal sent by the control module 101;

[0097] The second power supply module 103 is configured to output a power supply voltage signal that meets the output voltage requirement of the target first power supply module 102 under the control of the voltage control signal sent by the control module 101 .

[0098] In some embodiments, the motherboard power supply circuit 10 can be applied to computer equipment such as servers and switches. The motherboard power supply circuit 10 can be set in the motherboard of the computer equipment to provide power to components on the motherboard.

[0099] In some embodiments of the present application, the plurality of first power modules 102 may include power modules with different output voltage values, such as first power modules of 5 volts (V), 3.3V, 1.8V, etc. for powering a server motherboard. It should be noted that in the related art, for power modules with certain characteristic output voltage values, a backup power module is usually provided, such as the P5V and P5V_STBY power supplies on the server motherboard. However, the P5V_STBY power supply is not a redundant backup of the P5V power supply. In the power-on sequence, the P5V_STBY power supply is powered on first, and the P5V power supply is powered on later. The P5V_STBY power supply and the P5V power supply belong to the same voltage system and can each provide a 5V power output voltage.

[0100] In some embodiments, the second power module 103 may be a variable voltage power module with a variable output voltage. Upon receiving a voltage control signal from the control module 101, the second power module 103 may adjust its output voltage according to the output voltage requirement indicated by the voltage control signal, so that the power supply voltage signal output by the second power module 103 meets the output voltage requirement indicated by the voltage control signal. This provides a redundant backup for the first power module 102 at risk of failure, i.e., the target first power module 102.

[0101] In some embodiments, the first switch module 104 can be a multi-way switch, which is electrically connected to the second power supply module 103 and the first output terminal 1022 of each of the multiple first power supply modules 102. When receiving the switching control signal sent by the control module 101, the multi-way switch can connect the second power supply module 103 with the first output terminal 1022 of the target first power supply module 102 according to the first power supply module 102 with a failure risk indicated by the switching control signal, that is, the target first power supply module 102, so that the power supply voltage signal output by the second power supply module 103 is transmitted to the first output terminal 1022 of the target first power supply module 102, thereby powering the corresponding components of the target first power supply module 102.

[0102] In some embodiments, the first output terminal 1022 of the first power module 102 is configured to output a power voltage signal that meets the output voltage requirement of the first power module 102. The first output terminal 1022 of the first power module 102 can be connected to the power input terminal of a subsequent component to provide power to the subsequent component. The output voltage requirement refers to the difference between the actual output voltage value and the ideal output voltage value being less than a preset power voltage difference threshold. The power voltage difference threshold can be determined based on actual conditions and is not limited in this embodiment of the present application.

[0103] In some embodiments, the power health status of the first power module 102 may include parameters such as voltage, current, and temperature of the first power module 102. The detection component 1021 may include a detection unit for detecting parameters such as voltage, current, and temperature. The detection component 1021 may determine the power health status of the first power module 102 by acquiring detection data of the voltage, current, temperature, and other parameters of the first power module 102. The detection component 1021 may pre-process and analyze the detection data of the voltage, current, temperature, and other parameters of the first power module 102 to determine whether the first power module 102 is at risk of failure. If the first power module 102 is at risk of failure, the first power module 102 is determined as a target first power module 102, and a target detection result is generated and reported to the control module 101.

[0104] Among them, the preprocessing process of the detection component 1021 may include signal filtering of the detection signal sent by each detection unit, removing noise and interference, and performing signal authenticity processing to obtain high-quality detection data. The data analysis process of the detection component 1021 may include performing fault risk estimation on the detection signal sent by the detection unit according to a preset parameter threshold value to determine whether the first power supply module 102 has a fault risk. Specifically, the detection component 1021 can pre-store detection data of parameters such as voltage, current, and temperature under the healthy working condition of the first power supply module 102, and preset parameter thresholds for each parameter. By comparing and analyzing the detection signal of each parameter obtained in real time with the parameter threshold value of each parameter and the detection data under healthy working conditions, when the detection signal exceeds the parameter threshold value, or the offset between the detection signal and the detection data under healthy working conditions exceeds the risk warning amount, it can be determined that the first power supply module 102 has a fault risk. This is only an example, and the embodiments of the present application are not limited to this.

[0105] In some embodiments, the detection component 1021 can pre-process the detection data of the voltage, current, temperature and other parameters of the first power module 102, and then report the processed detection data as the first detection result to the control module 101. The control module 101 comprehensively analyzes and processes the first detection results sent by the detection component 1021 of each first power module 102, and predicts the power failure trend based on the historical fault data and the characteristic values ​​of the current detection results. If a first power module 102 with a failure risk is determined, the first power module 102 is determined as the target first power module 102, and a voltage control signal and a switching control signal are generated. The circuit connection relationship of the mainboard power circuit 10 is fault reconstructed, and the target first power module 102 is backed up for power redundancy through the second power module 103. In this way, the detection component 1021 only needs to perform simple data collection and preprocessing, and there is no need to set up a processing unit with higher computing power, which can reduce the cost of a single first power supply module 102. The control module 101 performs comprehensive analysis and processing on the health status data of each first power supply module 102, which can improve the accuracy of power supply fault trend prediction to a certain extent and obtain a more reasonable fault reconstruction strategy.

[0106] In related technologies, server-level redundancy is typically chosen, and server products generally use redundant server power supplies (CRPS), which can enhance the reliability of the server's external power supply. However, for the internal components of a single server system, such as the CPU power supply, complex programmable logic device (CPLD) power supply, double data rate synchronous dynamic random access memory (DDR) power supply, and function expansion card (Riser) power supply within the server motherboard, there are relatively few redundant designs. However, in server motherboard design, the internal power supply design is undoubtedly the most critical part. The stable and reliable power supply quality of each low-voltage system within the server directly determines the server's operating performance and service life.

[0107] Figure 2 is a schematic diagram of a redundant power supply system for a server CPU in the related art. As shown in Figure 2, the power supply system includes a first redundant module, a second redundant module, an MCU, and a CPU. The first and second redundant modules are used to power the CPU, ensuring stable and reliable power supply from the power supply system. However, the first and second redundant modules replicate the functionality of the power supply module. If this method were used for redundant backup of all key components within the server based on their functions and power levels, a large number of redundant modules would be required, resulting in excessive redundancy. Furthermore, to further improve reliability, the number of redundant modules would have to be increased, which would in turn lead to high costs.

[0108] Figure 3 is a circuit diagram of a redundant hot-backup industrial Ethernet switch power supply in the related art. As shown in Figure 3, the key to the circuit is that it includes at least two isolated power modules, a voltage monitoring unit, and a switching switch. However, the circuit also has two identical power modules with functional replication, which is only redundancy for a single functional node. If redundant backup designs are used at multiple key voltage operating points of a server or switch, there will be excessive redundancy in the power system, which will lead to high costs.

[0109] In some embodiments, when the target first power module 102 fails, the detection component 1021 of the target first power module 102 outputs a target detection result through power health status detection, and the control module 101 determines the first power module 102 that is at risk of failure based on the target detection result, generates a voltage control signal and a switching control signal, and controls the first switch module 104 through the switching control signal to connect the second power module 103 with the first output end 1022 of the target first power module 102, and controls the second power module 103 through the voltage control signal to output a power voltage signal that meets the output voltage requirements of the target first power module 102, and transmits it to the first output end 1022 of the target first power module 102 through the first switch module 104. In this way, there is no need to perform redundant backup for multiple first power modules 102. The first power module 102 with a failure risk can be determined through the detection component 1021 of each first power module 102. Through the control signal sent by the control module 101, when any first power module 102 has a failure risk, the second power module 103 is connected to the first output end 1022 of the target first power module 102 through the first switch module 104, and the second power module 103 outputs a power supply voltage signal that meets the output voltage requirements, so that the second power module 103 provides redundant backup for each first power module 102, which can reduce the number of circuit elements of the mainboard power supply circuit 101, reduce the power supply area overhead, and thus reduce the cost of the mainboard power supply circuit.

[0110] Moreover, for the power supply circuit of the motherboard in the related art, it is only necessary to add a second power supply module 103 and a detection component 1021 to the circuit, without having to change the main power circuit part of each first power supply module 102 of the circuit, thereby reducing the modification cost of the power supply circuit of the motherboard in the related art and improving the practicality of the motherboard power supply circuit 10 of the embodiment of the present application.

[0111] In some embodiments, the first power module 102 further includes: a first input terminal 1023 and a main power circuit 1024; the main power circuit 1024 is electrically connected to the first input terminal 1023 and the first output terminal 1022 respectively; the detection component 1021 includes: a detection submodule and a health control submodule 10212;

[0112] The detection submodule is electrically connected to the first input terminal 1023, the main power circuit 1024, the first output terminal 1022 and the health control submodule 10212, respectively, and is used to obtain health status data of the first power module 102 and send the health status data to the health control submodule 10212;

[0113] The health management submodule 10212 is electrically connected to the control module 101 , and is configured to process the health status data, obtain a first detection result, and send the first detection result to the control module 101 .

[0114] In some embodiments, the main power circuit 1024 may include power devices such as capacitors, inductors, and power transistors. The detection submodule detects parameters such as current, voltage, and temperature of the first power module 102, obtains detection signals of the current, voltage, and temperature parameters as health status data of the first power module 102, and sends the health status data to the health control submodule 10212. The health control submodule 10212 may process the health status data. Specifically, it may perform pre-processing such as signal filtering on the detection signals of the current, voltage, and temperature parameters to remove noise and interference, and use the processed health status data as the first detection result. The first detection result is then sent to the control module 101 for comprehensive data analysis by the control module 101.

[0115] In some embodiments, the detection submodule includes an input current detection unit 10211a and an output current detection unit 10211b;

[0116] The input current detection unit 10211a is electrically connected to the first input terminal 1023 and is connected in series in the main power circuit 1024, and is used to obtain input current data and send the input current data to the health control submodule 10212;

[0117] The output current detection unit 10211b is electrically connected to the first output terminal 1022 and is connected in series in the main power circuit 1024, for obtaining output current data and sending the output current data to the health control submodule 10212; wherein the health status data includes input current data and output current data.

[0118] In the embodiment of the present application, the input current detection unit 10211a and the output current detection unit 10211b can each include a sampling resistor, which is connected in series in the main power circuit 1024 to sample the input current or output current of the first power module 102. Specifically, to improve the accuracy of the input current data and the output current data, a high-precision sampling resistor can be used, so that the sampled data can be highly reliable.

[0119] In some embodiments, the input current detection unit 10211a includes: a first mutual inductance coil 10211a1, a second mutual inductance coil 10211a2, and a first detection subunit 10211a3; the turns ratio of the first mutual inductance coil 10211a1 to the second mutual inductance coil 10211a2 meets a first preset ratio, and the number of turns of the first mutual inductance coil 10211a1 is less than a preset turns threshold;

[0120] The first mutual inductance coil 10211a1 is electrically connected to the first input terminal 1023 and is connected in series to the main power circuit 1024;

[0121] The first detection subunit 10211a3 is electrically connected to the second mutual inductance coil 10211a2 and the health control submodule 10212 respectively, and is used to obtain input current data and send the input current data to the health control submodule 10212.

[0122] In some embodiments, the input current detection unit 10211a can use a current mutual induction coil method to determine the conversion ratio of the current on the first mutual induction coil 10211a1 to the current on the second mutual induction coil 10211a2 through a first preset ratio, thereby detecting the input current of the first power module 102 and obtaining input current data. The preset turns threshold can be set relatively small, so that the number of turns connected in series with the main power circuit 1024 is small, which can avoid affecting the power supply. For example, if the preset turns threshold is 2 and the first preset ratio can be 1:100, then the turns ratio of the first mutual induction coil 10211a1 to the second mutual induction coil 10211a2 is also 1:100, and the first mutual induction coil 10211a1 can be connected in series with the main power circuit with one turn. This is merely an example, and the embodiments of the present application are not limited thereto.

[0123] In some embodiments, when the first preset ratio is known and the current size on the second mutual inductance coil 10211a2 is detected, the current size on the first mutual inductance coil 10211a1 can be converted to obtain input current data and given to the health control sub-module 10212. Since the number of turns of the first mutual inductance coil 10211a1 is less than the preset turn threshold, the number of turns connected in series in the main power circuit 1024 can be limited, which can avoid the input current detection unit 10211a from affecting the power of the first power module 102, and can improve the reliability of the mainboard power supply circuit 10 of the embodiment of the present application.

[0124] In some embodiments, the output current detection unit 10211b includes: a third mutual inductance coil 10211b1, a fourth mutual inductance coil 10211b2, and a second detection subunit 10211b3; the turns ratio of the third mutual inductance coil 10211b1 to the fourth mutual inductance coil 10211b2 meets a second preset ratio;

[0125] The third mutual inductance coil 10211b1 is electrically connected to the first output terminal 1022 and is connected in series to the main power circuit 1024;

[0126] The second detection subunit 10211b3 is electrically connected to the fourth mutual inductance coil 10211b2 and the health control submodule 10212 respectively, and is used to obtain output current data and send the output current data to the health control submodule 10212.

[0127] In some embodiments, the output current detection unit 10211b can utilize a current mutual induction coil method, determining the conversion ratio of the current on the third mutual induction coil 10211b1 to the current on the fourth mutual induction coil 10211b2 using a second preset ratio, thereby detecting the output current of the first power module 102 and obtaining output current data. The preset turns threshold can be set relatively low, so that the number of turns connected in series with the main power circuit 1024 is small, thereby avoiding any impact on the power supply. For example, if the preset turns threshold is 2 and the second preset ratio can be 1:100, then the turns ratio of the third mutual induction coil 10211b1 to the fourth mutual induction coil 10211b2 is also 1:100, and the third mutual induction coil 10211b1 can be connected in series with one turn of the main power circuit. This is merely an example, and the embodiments of the present application are not limited thereto.

[0128] In some embodiments, when the second preset ratio is known and the current size on the fourth mutual inductance coil 10211b2 is detected, the current size on the third mutual inductance coil 10211b1 can be converted to obtain the output current data and give it to the health control sub-module 10212. Since the number of turns of the third mutual inductance coil 10211b1 is less than the preset turn threshold, the number of turns connected in series in the main power circuit 1024 can be limited, which can avoid the output current detection unit 10211b from affecting the power of the first power module 102, and can improve the reliability of the mainboard power supply circuit 10 of the embodiment of the present application.

[0129] In some embodiments, since the input current detection unit 10211a is electrically connected to the first input terminal 1023 and is connected in series in the main power circuit 1024, the current on the input side of the first power module 102 can be detected, and the input current data can be obtained and sent to the health control sub-module 10212. Since the output current detection unit 10211b is electrically connected to the first output terminal 1022 and is connected in series in the main power circuit 1024, the current on the output side of the first power module 102 can be detected, and the output current data can be obtained and sent to the health control sub-module 10212, so that the health control sub-module 10212 can analyze the power health status of the first power module 102 through the input current data and the output current data, thereby improving the practicality of the mainboard power supply circuit 10 of the embodiment of the present application.

[0130] In some embodiments, the first power module 102 further includes a circuit negative terminal 1025, which is electrically connected to the main power circuit 1024; the detection submodule includes an input voltage detection unit 10211c and an output voltage detection unit 10211d;

[0131] The input voltage detection unit 10211c is electrically connected to the first input terminal 1023 and the loop negative terminal 1025, respectively, for obtaining input voltage data and sending the input voltage data to the health control submodule 10212;

[0132] The output voltage detection unit 10211d is electrically connected to the first output terminal 1022 and the loop negative terminal 1025 respectively, and is used to obtain output voltage data and send the output voltage data to the health control submodule 10212; wherein the health status data includes input voltage data and output voltage data.

[0133] In some embodiments, the input voltage detection unit 10211c is connected in parallel to the input port of the first power module 102, and is used to detect the input port voltage of the first power module 102, obtain input voltage data, and send it to the health management submodule 10212. The output voltage detection unit 10211d is connected in parallel to the output port of the first power module 102, and is used to detect the output port voltage of the first power module 102, obtain output voltage data, and send it to the health management submodule 10212.

[0134] In some embodiments, the first power module 102 further includes a first capacitor 1026 and a second capacitor 1027; the first capacitor 1026 is electrically connected to the first input terminal 1023 and the negative terminal 1025 of the loop, respectively; the second capacitor 1027 is electrically connected to the first output terminal 1022 and the negative terminal 1025 of the loop, respectively;

[0135] The input voltage detection unit 10211c is further configured to obtain first impedance data corresponding to the first capacitor 1026 and send the first impedance data to the health control submodule 10212;

[0136] The output voltage detection unit 10211d is further used to obtain the second impedance data corresponding to the second capacitor 1027 and send the second impedance data to the health control submodule 10212; wherein the health status data includes the first impedance data and the second impedance data.

[0137] In some embodiments, the first capacitor 1026 may be a bus capacitor connected in parallel with the input bus of the first power module 102. The second capacitor 1027 may be a bus capacitor connected in parallel with the output bus of the first power module 102. The first capacitor 1026 is connected in parallel to the input port of the first power module 102. The input voltage detection unit 10211c can be used to perform impedance detection on the first capacitor 1026, obtain first impedance data corresponding to the first capacitor 1026, and send it to the health management submodule 10212. The second capacitor 1027 is connected in parallel to the output port of the first power module 102. The output voltage detection unit 10211d can be used to perform impedance detection on the second capacitor 1027, obtain second impedance data corresponding to the second capacitor 1027, and send it to the health management submodule 10212.

[0138] In some embodiments, since the first capacitor 1026 is electrically connected to the first input terminal 1023 and the negative terminal 1025 of the loop respectively, the first capacitor 1026 can be impedance detected by the input voltage detection unit 10211c, and the first impedance data corresponding to the first capacitor 1026 is obtained and sent to the health control sub-module 10212. Since the second capacitor 1027 is electrically connected to the first output terminal 1022 and the negative terminal 1025 of the loop respectively, the second capacitor 1027 can be impedance detected by the output voltage detection unit 10211d, and the second impedance data corresponding to the second capacitor 1027 is obtained and sent to the health control sub-module 10212, so that the health control sub-module 10212 can analyze the power health status of the first power module 102 through the first impedance data and the second impedance data, thereby improving the practicality of the mainboard power supply circuit 10 of the embodiment of the present application.

[0139] In some embodiments, since the input voltage detection unit 10211c is electrically connected to the first input terminal 1023 and the negative terminal 1025 of the loop respectively, the voltage on the input side of the first power module 102 can be detected, and the input voltage data can be obtained and sent to the health control sub-module 10212. Since the output voltage detection unit 10211d is electrically connected to the first output terminal 1022 and the negative terminal 1025 of the loop respectively, the voltage on the output side of the first power module 102 can be detected, and the output voltage data can be obtained and sent to the health control sub-module 10212, so that the health control sub-module 10212 can analyze the power health status of the first power module 102 through the input voltage data and the output voltage data, thereby improving the practicality of the mainboard power supply circuit 10 of the embodiment of the present application.

[0140] In some embodiments, the main power circuit 1024 includes a plurality of power devices; the detection submodule includes a temperature detection unit;

[0141] The temperature detection unit is electrically connected to the multiple power devices respectively, and is used to obtain temperature data of each of the multiple power devices and send the temperature data to the health control submodule 10212; wherein the health status data includes temperature data.

[0142] In some embodiments, the multiple power devices may include power devices such as capacitors, inductors and power tubes. The temperature detection unit may include multiple temperature sensors 10211e1 and a third detection subunit 10211e2. The third detection subunit 10211e2 is electrically connected to the multiple temperature sensors 10211e1 and the health control submodule 10212 respectively. One power device in the main power circuit 1024 is connected to a corresponding temperature sensor 10211e1. The temperature of each power device is detected by the temperature sensor 10211e1, and the temperature data of each of the multiple power devices is obtained, and the temperature data is sent to the health control submodule 10212. Specifically, the temperature sensor 10211e1 can be adhered to the power device to perform temperature detection on the power device. This is only an example, and the embodiments of the present application are not limited to this.

[0143] In some embodiments, since the temperature detection unit is electrically connected to multiple power devices respectively, the temperature detection unit can be used to perform temperature detection on multiple power devices respectively, and the temperature data of each of the multiple power devices can be obtained and sent to the health control sub-module 10212, so that the health control sub-module 10212 can analyze the power health status of the first power module 102 through the temperature data, thereby improving the practicality of the mainboard power circuit 10 of the embodiment of the present application.

[0144] In some embodiments, the mainboard power circuit 10 includes a second switch module 105; the plurality of first power modules 102 include same-voltage modules, and the same-voltage modules include first power modules 102 with the same output voltage requirements;

[0145] The control module 101 is also electrically connected to the second switch module 105 and is configured to send a first switch control signal to the second switch module 105 when any first power module 102 in the same voltage module has a failure risk and the second power module 103 is occupied;

[0146] The second switch module 105 is electrically connected to each first power supply module 102 in the same voltage module, and is used to connect the first output end 1022 of other first power supply modules 102 in the same voltage module with the first output end 1022 of the first power supply module 102 with a failure risk under the control of the first switch control signal; wherein the other first power supply module 102 is any first power supply module 102 in the same voltage module that does not have a failure risk.

[0147] In some embodiments, when the control module 101 receives the target detection result and determines that the target first power module 102 has a failure risk and the second power module 103 is not occupied, the control module 101 can directly send a switching control signal to the first switch module 104 to control the first switch module 104 to connect the second power module 103 with the first output terminal 1022 of the target first power module 102. The control module 101 can send a voltage control signal to the second power module 103 so that the second power module 103 outputs a power voltage signal that meets the output voltage requirements of the target first power module 102, and transmits it to the first output terminal 1022 of the target first power module 102 to power the corresponding components of the target first power module 102.

[0148] In some embodiments, a common voltage module refers to a combination of first power modules 102 belonging to the same voltage system, where each first power module 102 in the common voltage module can output a power voltage signal with the same voltage value. For example, the P5V and P5V_STBY power supplies on a server motherboard belong to the same voltage system and can each provide a 5V power output voltage, and can serve as the common voltage module in the embodiments of the present application.

[0149] In some embodiments, when the control module 101 receives the target detection result and determines that the target first power module 102 has a failure risk, and the second power module 103 has been occupied by the first power module 102 that previously had a failure risk, if the current target first power module 102 belongs to a same voltage module, the control module 101 can send a first switch control signal to the second switch module 105, and through the second switch module 105, connect the first output end 1022 of other first power modules 102 in the same voltage module to the first output end 1022 of the current target first power module 102. Since the other first power modules 102 are any first power modules 102 in the same voltage module that do not have a failure risk, the other first power modules 102 can be used to power the corresponding components of the current target first power module 102, that is, the first power module 102 in a healthy state in the same voltage module provides redundant backup for the target first power module 102.

[0150] In some embodiments, there are multiple same-voltage modules, multiple second switch modules 105 , and the same-voltage modules are connected to the second switch modules 105 in a one-to-one correspondence;

[0151] The control module 101 is also electrically connected to a plurality of second switch modules 105, respectively, and is configured to send a second switch control signal to the target second switch module 105 when the same-voltage module where the latest target first power module 102 is located cannot supply power normally and the second power module 103 is occupied; wherein the target second switch module 105 is the second switch module 105 corresponding to the target same-voltage module, and the target same-voltage module is the same-voltage module where the first power module 102 currently corresponding to the second power module 103 is located;

[0152] The second switch module 105 is electrically connected to each first power module 102 in the corresponding same-voltage module. The target second switch module 105 is used to connect the first output terminal 1022 of other first power modules 102 in the target same-voltage module to the first output terminal 1022 of the first power module 102 currently corresponding to the second power module 103 under the control of the second switch control signal.

[0153] The first switch module 104 is specifically configured to, under the control of a switching control signal, conduct the connection between the second power module 103 and the first output terminal 1022 of the first power module 102 that is most recently at risk of failure.

[0154] In some embodiments, when the control module 101 receives the target detection result and determines that the latest target first power module 102 has a failure risk, the second power module 103 has been occupied by the first power module 102 that previously had a failure risk, and the same voltage module where the latest target first power module 102 is located cannot supply power normally, if the same voltage module where the first power module 102 currently corresponding to the second power module 103 is located has the ability to supply power normally, then the fault reconstruction can be performed by adjusting the connection relationship of the second power module 103, and the other first power modules 102 in the same voltage module where the first power module 102 currently corresponding to the second power module 103 is located provide redundant backup for the first power module 102 currently corresponding to the second power module 103, and then release the second power module 103, and the second power module 103 performs redundant backup for the latest target first power module 102. In this way, when multiple first power modules 102 fail and the same voltage module where the latest target first power module 102 is located cannot supply power normally, the mainboard power circuit 10 can be fault reconstructed through flexible switching logic, thereby improving the safety of the mainboard power circuit 10 of the embodiment of the present application.

[0155] Specifically, a corresponding second switch module 105 is connected to a same-voltage module, and the second switch module 105 is electrically connected to the first output terminal 1022 of each first power module 102 in the same-voltage module. If the same-voltage module where the latest target first power module 102 is located cannot supply power normally and the second power module 103 is occupied, the control module 101 can send a second switch control signal to the target second switch module 105. In response to the second switch control signal, the target second switch module 105 connects the first output terminal 1022 of other first power modules 102 in the target same-voltage module to the first output terminal 1022 of the first power module 102 currently corresponding to the second power module 103. The other first power modules 102 can then power subsequent components of the first power module 102 currently corresponding to the second power module 103. In other words, the healthy first power module 102 in the same-voltage module provides redundant backup for the first power module 102 currently corresponding to the second power module 103, releasing the second power module 103.

[0156] In some embodiments, the control module 101 can control the first switch module 104 to conduct the connection between the released second power supply module 103 and the first output end 1022 of the latest target first power supply module 102 by switching the control signal, so that the second power supply module 103 outputs a power supply voltage signal that meets the output voltage requirements of the latest target first power supply module 102, and transmits it to the first output end 1022 of the latest target first power supply module 102 to power the corresponding components of the latest target first power supply module 102.

[0157] In an embodiment of the present application, the mainboard power supply circuit 10 may include multiple same-voltage modules. When one of the same-voltage modules fails as a whole, that is, the same-voltage module where the latest target first power module 102 is located cannot supply power normally, and the second power module 103 is occupied, the occupied second power module 103 can be released, and the second power module 103 can perform redundant backup for the same-voltage module. The first power module 102 originally connected to the second power module 103 can be redundantly backed up by any first power module 102 in the same-voltage module to which it belongs that does not have a risk of failure, that is, other first power modules 102. In this way, when the same-voltage module where the latest target first power module 102 is located cannot supply power normally, and the second power module 103 is occupied, the mainboard power supply circuit 10 can be fault-reconstructed through flexible switching logic, and the occupied second power module 103 can be released, so that the first power modules 102 with a risk of failure in the circuit are all redundantly backed up by the first power module 102 or the second power module 103 in a healthy state, thereby improving the reliability of the mainboard power supply circuit 10 in an embodiment of the present application.

[0158] In some embodiments, the second switch module 105 includes: a first transistor 1051 and a second transistor 1052; the same voltage module includes two first power modules 102 with the same output voltage requirement;

[0159] A first electrode of the first transistor 1051 is electrically connected to the first output terminal 1022 of a first power supply module 102 in the corresponding same voltage module, and a second electrode of the first transistor 1051 is electrically connected to the first electrode of the second transistor 1052;

[0160] The second electrode of the second transistor 1052 is electrically connected to the first output terminal 1022 of another first power supply module 102 in the corresponding same voltage module;

[0161] The control module 101 is also electrically connected to the control electrodes of the first transistor 1051 and the second transistor 1052, respectively, and is specifically used to send a first switching control signal to the first transistor 1051 and the second transistor 1052 to control the first transistor 1051 and the second transistor 1052 to be turned on when there is a risk of failure in any first power module 102 in the same voltage module and the second power module 103 is occupied.

[0162] In some embodiments, the first transistor 1051 may be a metal-oxide-semiconductor (MOS) field-effect transistor, such as an N-channel metal-oxide-semiconductor field-effect transistor (NMOS) or a P-channel metal-oxide-semiconductor field-effect transistor (PMOS). A MOS transistor is a switch, comprising a gate, a source, and a drain. The gate is a control electrode, which controls whether the source and drain are conductive, i.e., whether current can pass through. For an NMOS transistor, the gate is active when it is high, while for a PMOS transistor, the gate is active when it is low.

[0163] The control electrode of the first transistor 1051 may be the gate of a MOS transistor, the first electrode of the first transistor 1051 may be the source or drain of the MOS transistor, and correspondingly, the second electrode of the first transistor 1051 may be the drain or source of the MOS transistor. Specifically, when the first transistor 1051 is a PMOS transistor, the first electrode of the first transistor 1051 may be the source of the PMOS transistor, and the second electrode of the first transistor 1051 may be the drain of the PMOS transistor. This is merely an example, and the embodiments of the present application are not limited thereto.

[0164] In some embodiments, the second transistor 1052 may be a MOS transistor, such as an NMOS transistor or a PMOS transistor. The control electrode of the second transistor 1052 may be the gate of the MOS transistor, the first electrode of the second transistor 1052 may be the source or drain of the MOS transistor, and accordingly, the second electrode of the second transistor 1052 may be the drain or source of the MOS transistor. Specifically, when the second transistor 1052 is an NMOS transistor, the first electrode of the second transistor 1052 may be the source of the NMOS transistor, and the second electrode of the second transistor 1052 may be the drain of the NMOS transistor. This is merely an example, and the embodiments of the present application are not limited thereto.

[0165] In some embodiments, the first transistor 1051 may be a PMOS transistor, and the second transistor 1052 may be an NMOS transistor. The control module 101 is further electrically connected to the control electrodes of the first transistor 1051 and the second transistor 1052, respectively. The source of the first transistor 1051 (PMOS transistor) is electrically connected to the first output terminal 1022 of one first power supply module 102 in the same voltage module. The drain of the first transistor 1051 (PMOS transistor) is electrically connected to the source of the second transistor 1052 (NMOS transistor). The drain of the second transistor 1052 (NMOS transistor) is also electrically connected to the first output terminal 1022 of another first power supply module 102 in the same voltage module. It should be noted that a single MOS transistor can only block current in one direction. In the embodiment of the present application, two MOS transistors connected in series can achieve bidirectional blocking. When redundant backup is not required between the first power supply modules 102 in the same voltage module, the first output terminals 1022 of the two first power supply modules 102 are disconnected.

[0166] In some embodiments, the first switch control signal may include a first sub-signal and a second sub-signal, where the first sub-signal is used to control the conduction of the first transistor 1051, and the second sub-signal is used to control the second transistor 1052. Specifically, if the first transistor 1051 is a PMOS transistor, the first sub-signal may be a low-level signal, and if the second transistor 1052 is an NMOS transistor, the second sub-signal may be a high-level signal. This is merely an example and is not limited in the present application.

[0167] In some embodiments, since the first pole of the first transistor 1051 is electrically connected to the first output end 1022 of a first power supply module 102 in the corresponding same voltage module, the second pole of the first transistor 1051 is electrically connected to the first pole of the second transistor 1052, and the second pole of the second transistor 1052 is electrically connected to the first output end 1022 of another first power supply module 102 in the corresponding same voltage module, therefore, when the control module 101 sends a first switch control signal to the control poles of the first transistor 1051 and the second transistor 1052 to control the first transistor 1051 and the second transistor 1052 to be turned on, the first output end 1022 of the first power supply module 102 with the same two output voltage requirements in the same voltage module is turned on, then the two first power supply modules 102 in the same voltage module can serve as redundant backups for each other, thereby improving the scalability of the mainboard power supply circuit 10 of the embodiment of the present application.

[0168] In some embodiments, the mainboard power supply circuit 10 further includes a surge suppression unit 106 and a transient energy providing unit 107; the transient energy providing unit 107 is electrically connected to the surge suppression unit 106, and the surge suppression unit 106 is electrically connected to the control module 101 and the first switch module 104 respectively;

[0169] The control module 101 is further configured to send a transient control signal to the surge suppression unit 106 when the power supply capacity of the second power supply module 103 is insufficient;

[0170] The surge suppression unit 106 is configured to connect the transient energy providing unit 107 to the target first power supply module 102 under the control of the transient control signal.

[0171] In some embodiments, the plurality of first power modules 102 may include a high-current power module. When the high-current power module is at risk of failure, that is, when the high-current power module is determined to be the target first power module 102, the second power module 103 may have insufficient power supply capacity. The control module 101 can send a transient control signal to the surge suppression unit 106, causing the surge suppression unit 106 to connect the transient energy supply unit 107 to the target first power module 102. The transient energy supply unit 107 can improve the transient power supply capacity, provide a redundant backup for the high-current power module, that is, the target first power module 102, and the surge suppression unit 106 can suppress the surge current to prevent the surge current from damaging circuit components.

[0172] In some embodiments, since the transient energy supply unit 107 is electrically connected to the surge suppression unit 106, and the surge suppression unit 106 is electrically connected to the control module 101 and the first switch module 104 respectively, the control module 101 can send a transient control signal to the surge suppression unit 106 when the power supply capacity of the second power supply module 103 is insufficient, and control the surge suppression unit 106 through the transient control signal to turn on the connection between the transient energy supply unit 107 and the target first power supply module 102, so that the transient energy supply unit 107 improves the transient power supply capacity, and the surge suppression unit 106 suppresses the surge current to prevent the surge current from damaging circuit components.

[0173] In some embodiments, the first switch module 104 includes a multi-way switch;

[0174] The multi-way switch is electrically connected to the control module 101 , the second power module 103 , and the first output terminals 1022 of the plurality of first power modules 102 .

[0175] In some embodiments, the multi-way switch can be a switching element such as a single-pole multi-throw switch or a multi-way selector, which is used to switch between the first output terminals 1022 of each first power supply module 102 under the control of the switching control signal sent by the control module 101, and to connect the second power supply module 103 with the first output terminal 1022 of any first power supply module 102.

[0176] In some embodiments, a multi-way switch can be used to conveniently switch between the first output terminals 1022 of each first power supply module 102. Under the control of the switching control signal sent by the control module 101, the connection between the second power supply module 103 and the first output terminal 1022 of any first power supply module 102 is turned on, so that the second power supply module 103 provides redundant backup for the first power supply module 102 that is at risk of failure. This has the advantages of a simple circuit structure and simple switching logic, and can reduce circuit costs.

[0177] In some embodiments, the control module 101 is specifically configured to:

[0178] receiving a first detection result sent by each first power supply module 102;

[0179] Acquire historical fault data, and predict power supply fault trends based on each first detection result and the historical fault data;

[0180] When the fault prediction result corresponding to any first power module 102 is higher than a preset risk threshold, a voltage control signal and a switching control signal are generated; wherein the first power module 102 is a target first power module 102, and the first detection result sent by the target first power module 102 is a target detection result;

[0181] A voltage control signal is sent to the second power supply module 103 , and a switching control signal is sent to the first switch module 104 .

[0182] In some embodiments, the first detection result may be detection data of the voltage, current, temperature and other parameters of each first power module 102 after being pre-processed by the detection component 1021. The historical fault data may be detection data of the voltage, current, temperature and other parameters of the first power module 102 that has already failed at the time of the failure, or may be detection data of the voltage, current, temperature and other parameters of the first power module 102 that has issued a fault warning at the time of the warning, and the embodiments of the present application do not limit this. Among them, the fault warning refers to the detection component 1021 of the first power module 102 sending the target detection result to the control module 101, indicating that the first power module 102 has a fault risk and issuing a fault warning to the first power module.

[0183] In some embodiments, feature analysis can be performed on each first detection result to extract characteristic values ​​of parameters such as voltage, current, and temperature. The fault alarm value can be determined based on the detection data of parameters such as voltage, current, and temperature corresponding to each first power supply module 102 at the time of failure or alarm obtained from historical fault data. By comparing the characteristic value of the parameter with the fault alarm value and a preset fault feature threshold, the power health status is judged, the fault risk is predicted, and a fault prediction result is obtained. The fault prediction result is compared with the preset risk threshold. If the fault prediction result is higher than the preset risk threshold, the control module 101 sends a voltage control signal and a switching control signal to control the first switch module 104 to perform fault reconstruction on the mainboard power supply circuit 10, and the first power supply module 102 provides redundant backup for the target first power supply module 102.

[0184] In some embodiments, the control module 101 performs a comprehensive analysis on the first detection results and historical fault data of each first power supply module 102, and predicts the power failure trend of each first power supply module 102, which can expand the data volume and improve the accuracy of the fault prediction results corresponding to the first power supply module 102. In this way, when the fault prediction result corresponding to any first power supply module 102 is higher than the preset risk threshold, the control module 101 sends a voltage control signal and a switching control signal to control the first switch module 104 to perform fault reconstruction on the mainboard power supply circuit 10, and the first power supply module 102 provides redundant backup for the target first power supply module 102. The power module can be switched in advance before the first power supply module 102 actually fails, so as to avoid affecting the power supply of subsequent components, thereby improving the reliability of the mainboard power supply circuit 10 of the embodiment of the present application.

[0185] In some embodiments, the motherboard power supply circuit 10 is provided in a computer device, and the computer device includes a background unit; the control module 101 is further configured to:

[0186] Sending the first detection result and fault prediction result of each first power module 102, as well as the voltage control signal and the switching control signal to the background unit;

[0187] When the calibration confirmation instruction sent by the background unit is received, the sending operation of the voltage control signal and the switching control signal is executed.

[0188] In some embodiments, the computer device may be a server, a switch, or the like, and the motherboard power supply circuit 10 may be provided on the motherboard of the computer device. Before the control module 101 performs fault reconstruction on the motherboard power supply circuit 10 via a control instruction, a fault alarm may be first issued to a background unit, and the first detection results and fault prediction results of each first power supply module 102, as well as the voltage control signal and the switching control signal, may be sent to the background unit. The background unit then calibrates the power supply health status, fault prediction results, and circuit reconstruction strategy. Upon receiving a calibration confirmation instruction from the background unit, the voltage control signal and the switching control signal are sent. The calibration confirmation instruction may be issued by a technician after calibrating and confirming the power supply health status, fault prediction results, and circuit reconstruction strategy. The background unit may store and record the power supply health status, fault prediction results, and circuit reconstruction strategy for subsequent power supply fault trend prediction as historical fault data or for data analysis by technicians.

[0189] In some embodiments, when the calibration time of the background unit exceeds a preset calibration waiting threshold, the control module 101 can directly execute the sending operation of the voltage control signal and the switching control signal. In this way, the delay of the calibration process can be avoided from affecting the normal power supply to the mainboard components, and the safety of the mainboard power supply circuit 10 can be improved.

[0190] In some embodiments, the first detection results and fault prediction results of each first power module 102, as well as the voltage control signal and the switching control signal, are sent to a background unit. The background unit then calibrates the power health status, fault prediction results, and circuit reconfiguration strategy. Upon receiving a calibration confirmation instruction from the background unit, the voltage control signal and the switching control signal are sent. In this way, the accuracy of the voltage control signal and the switching control signal can be further improved through the background unit's calibration process.

[0191] In some embodiments, the control module 101 is specifically configured to:

[0192] For any first detection result, the health status characteristic value of the corresponding first power module 102 is extracted from the first detection result.

[0193] Obtaining a fault alarm value of each first power module 102 from historical fault data;

[0194] For any first power module 102 , a fault prediction result of the first power module 102 is determined according to the health status characteristic value, the fault alarm value, and the preset fault characteristic threshold.

[0195] In some embodiments, feature analysis can be performed on each first detection result to extract characteristic values ​​of parameters such as voltage, current, and temperature as the corresponding health status characteristic value of the first power module 102. A fault alarm value can be determined based on the detection data of parameters such as voltage, current, and temperature corresponding to each first power module 102 at the time of the fault or alarm, obtained from historical fault data. The health status characteristic value is compared with the fault alarm value and a preset fault characteristic threshold to determine the health status of the power supply and determine whether the current health status characteristic value exceeds the fault alarm value or the fault characteristic threshold, thereby predicting the fault risk. When the health status characteristic value exceeds the fault alarm value or the fault characteristic threshold, the offset of the health status characteristic value is determined as the fault prediction result.

[0196] In some embodiments, a health status characteristic value of the corresponding first power module 102 is extracted from the first detection result, and a fault warning value for each first power module 102 is obtained from historical fault data. For each first power module 102, a fault prediction result for the first power module 102 is determined based on the health status characteristic value, the fault warning value, and a preset fault characteristic threshold. In this way, a comprehensive data analysis can be performed based on the health status characteristic value obtained from the current detection and the fault warning value obtained from the historical fault data to determine the fault prediction result for the first power module 102. This can increase the amount of data and improve the accuracy of the fault prediction result.

[0260] The specific implementation of the power health management method can refer to the relevant description in the aforementioned embodiment and will not be repeated here.

[0261] In some embodiments, when the target first power module 102 fails, the detection component 1021 of the target first power module 102 outputs a target detection result through power health status detection, and the control module 101 determines the first power module 102 that is at risk of failure based on the target detection result, generates a voltage control signal and a switching control signal, and controls the first switch module 104 through the switching control signal to connect the second power module 103 with the first output end 1022 of the target first power module 102, and controls the second power module 103 through the voltage control signal to output a power voltage signal that meets the output voltage requirements of the target first power module 102, and transmits it to the first output end 1022 of the target first power module 102 through the first switch module 104. In this way, there is no need to perform redundant backup for multiple first power modules 102. The first power module 102 with a failure risk can be determined through the detection component 1021 of each first power module 102. Through the control signal sent by the control module 101, when any first power module 102 has a failure risk, the second power module 103 is connected to the first output end 1022 of the target first power module 102 through the first switch module 104, and the second power module 103 outputs a power supply voltage signal that meets the output voltage requirements, so that the second power module 103 provides redundant backup for each first power module 102, which can reduce the number of circuit elements of the mainboard power supply circuit 101, reduce the power supply area overhead, and thus reduce the cost of the mainboard power supply circuit.

[0262] Figure 7 is a timing diagram of a power health management method provided in an embodiment of the present application. As shown in Figure 7, this power health management method can be applied to the power health management of the motherboard power circuit of computer equipment such as servers. The operating sequence includes: After the motherboard power circuit is powered on, the input and output detection units and the temperature detection unit detect, in real time, the voltage, current, and temperature of the ports of each first power module 102 and of core power components such as power transistors, inductors, and capacitors. The detection data is comprehensively processed, and noise and interference signals are removed through signal filtering. Feature values ​​of the detection data of parameters such as voltage, current, and temperature are extracted to serve as health status feature values. The health status feature values ​​are compared and analyzed with pre-set fault feature thresholds to determine the power health status and obtain a fault prediction result. When a fault risk is detected in the first power module 102, a power supply remaining life alarm is issued. A fault reconfiguration strategy is derived based on the fault prediction result. The first detection result and fault prediction result, as well as the voltage control signal and the switching control signal, are sent to the backend unit, which further calibrates the power health status, fault prediction result, and circuit reconfiguration strategy. Upon receiving the calibration confirmation instruction from the backend unit, the voltage control signal and the switching control signal are sent to reconfigure the mainboard power circuit 10 to address the circuit failure. The second power module 103 is used to provide a redundant backup for the target first power module 102. The backend unit can store and record the power health status, fault prediction results, and circuit reconfiguration strategy to serve as historical fault data for subsequent power failure trend prediction or for data analysis by technical personnel.

[0263] FIG8 is a second timing diagram of a power health management method provided by an embodiment of the present application. As shown in FIG8 , the operating timing includes: input side status detection and signal authenticity processing, filtering and reporting to the health management submodule 10212, which includes input voltage detection, input current detection, and input side impedance detection. Output side status detection and signal authenticity processing, filtering and reporting to the health management submodule 10212, which includes output voltage detection, output current detection, and output side impedance detection. Core temperature detection of each power device and signal authenticity processing, filtering and reporting to the health management submodule 10212, which includes inductor, capacitor, and power tube temperature detection. The health management submodule 10212 comprehensively compares and analyzes each data again, further processes the signal authenticity and filters it, and then reports it to the control module 101. The control module 101 further compares the input side, output side status, and the temperature status of each power device with the fault feature threshold in multiple dimensions, conducts comprehensive comparison and further compares and analyzes it with historical fault data, i.e., information fusion processing. According to the comprehensive comparison results, a power supply failure trend prediction is made and the remaining life of the power supply is predicted. According to the health status characteristic value, the fault alarm value and the fault characteristic threshold, the fault prediction result is determined. The control module 101 generates a voltage control signal and a switching control signal, i.e., a circuit reconstruction strategy, based on the fault prediction result, and reports the circuit reconstruction strategy to the background unit for calibration confirmation. Upon receiving the calibration confirmation instruction sent by the background unit, the voltage control signal and the switching control signal are sent, and the circuit fault reconstruction of the mainboard power supply circuit 10 is performed, and redundant backup of the target first power supply module 102 is achieved through the second power supply module 103. When the calibration time of the background unit exceeds the preset calibration waiting threshold, the control module 101 can directly execute the voltage control signal and the switching control signal sending operation,

[0264] FIG9 is a third timing diagram of a power health management method provided by an embodiment of the present application. As shown in FIG9 , the fault reconstruction timing is as follows: the control module 101 receives the target detection result and determines the voltage and current state required by the target first power module 102. It determines whether the second power module 103 is occupied. When the second power module 103 is not occupied, that is, when the second power module 103 is in an idle state, the second power module 103 is first adjusted to the output voltage corresponding to the target first power module 102, and the connection between the second power module 103 and the first output terminal 1022 of the target first power module 102 is connected through the first switch module 104. When the second power supply module 103 is occupied, the redundant backup capabilities of other first power supply modules 102 in the same voltage module to which the target first power supply module 102 belongs are further judged. If there is a first power supply module 102 in a healthy state in the same voltage module, the second switch module 105 is used to connect the first output end 1022 of other first power supply modules 102 in the same voltage module with the first output end 1022 of the target first power supply module 102, thereby realizing fault reconstruction between the same voltage modules.

[0265] If it is further determined that the same-voltage module where the latest target first power module 102 is located cannot supply power normally, it is further determined whether the same-voltage module where the first power module 102 currently corresponding to the second power module 103 is located has redundant backup capabilities. If it does, the target second switch module 105 is used to connect the first output terminals 1022 of other first power modules 102 in the target same-voltage module to the first output terminal 1022 of the first power module 102 currently corresponding to the second power module 103, thereby achieving fault reconstruction between the same-voltage modules and releasing the second power module 103. Then, the first switch module 104 is used to connect the second power module 103 to the first output terminal 1022 of the latest target first power module 102, and the second power module 103 performs redundant backup for the latest target first power module 102.

[0266] Referring to FIG. 4 , for example, if a P5V power supply architecture unit is at risk of failure, the second power module 102 is initially used as a redundant backup. If a P3V3 power supply architecture unit is also at risk of failure, the system first determines whether the P3V3_STBY power supply architecture unit is capable of providing redundant backup. If so, the P3V3_STBY power supply architecture unit provides redundant backup for the P3V3 power supply architecture unit, achieving circuit failure reconstruction. If the P3V3_STBY power supply architecture unit is insufficient, the system further determines whether the P5V_STBY power supply architecture unit is capable of providing redundant backup for the P5V power supply architecture unit. If so, the P5V_STBY power supply architecture unit provides redundant backup for the P5V power supply architecture unit, and then the second power module 102 is released. The second power module 102 then provides redundant backup for the P3V3 power supply architecture unit, achieving circuit failure reconstruction.
