[0052] With the continuous development of information technology, the computing and storage capabilities of servers are constantly improving, leading to a continuous increase in the power consumption of various components inside the server. Different components may operate at different voltages, so in order to provide a stable and reliable power supply to these high-power components, it is necessary to convert the single-board power supply to various operating voltages to meet the power supply requirements of the various components inside the server.

[0053] Figure 1 A schematic diagram of the power supply system for example related technologies, such as Figure 1 As shown, the power supply system of the related technology includes a single-board power supply, multiple components to be powered, and power conversion modules corresponding to each component. Different components require different operating voltages, so each power conversion module converts the single-board power supply to the operating voltage corresponding to the component, enabling the component to operate normally. However, in this related technology, each power conversion module corresponds one-to-one with each component. When any power conversion module fails, it will directly cause its corresponding component to stop working, leading to server malfunctions and low power supply reliability.

[0054] This application embodiment adds a backup power conversion module, multiple control switches, and a control module to the power supply system. The control module acquires the operating data of the multiple power conversion modules and determines whether there is an abnormal target power conversion module based on the operating data. If an abnormal target power conversion module is found, a conduction command is sent to the target control switch corresponding to the target power conversion module to turn it on. Simultaneously, the backup power conversion module is controlled to convert the voltage of the single-board power supply to the operating voltage of the component to be powered by the target control switch, thereby supplying power to the component to be powered by the target control switch. This ensures that if one power conversion module malfunctions, the backup power conversion module can supply power to the component corresponding to the malfunctioning power conversion module, thus ensuring the stable power supply to each component and improving the power supply stability of the power supply system.

[0055] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] Figure 2 A schematic diagram of the power supply system provided in the embodiments of this application. Figure 1 ,like Figure 2As shown, the system includes: a single-board power supply, multiple components to be powered, multiple power conversion modules, at least one backup power conversion module, multiple control switches, and a control module. The multiple power conversion modules, multiple components to be powered, and multiple control switches correspond one-to-one. The first terminal of the control module is connected to the first terminal of each of the multiple power conversion modules, and is used to send a first voltage conversion command to each of the multiple power conversion modules. The second terminals of each of the multiple power conversion modules are connected to the single-board power supply, and the third terminals are connected to the corresponding components to be powered, respectively, to convert the voltage of the single-board power supply into the operating voltage of the corresponding component to be powered, based on the first voltage conversion command, so as to supply power to the corresponding component. The first terminal of the control module is also connected to the first terminal of the backup power conversion module, and the second terminal is connected to the control switches. The control terminal is connected to acquire the operating data of multiple power conversion modules, and determines whether there is an abnormal target power conversion module based on the operating data of multiple power conversion modules. If an abnormal target power conversion module is found, a conduction command is sent to the target control switch corresponding to the target power conversion module to turn on the target control switch, and a second voltage conversion command is sent to the backup power conversion module. The second terminal of the backup power conversion module is connected to the single board power supply, and the third terminal is connected to the first terminal of multiple control switches. The second terminal of multiple control switches is connected to the corresponding components to be powered. When the target control switch is turned on, the voltage of the single board power supply is converted into the working voltage of the component to be powered corresponding to the target control switch based on the second voltage conversion command, so as to supply power to the component to be powered corresponding to the target control switch.

[0057] In a scenario example, the control module can be considered the control center of a Microcontroller Unit (MCU), serving as the central control module of the entire control system, responsible for data acquisition, logic calculation, and control command issuance. Communication between the control module and each power conversion module is bidirectional. On one hand, the control module sends a first voltage conversion command to each power conversion module, carrying the required output voltage value within this command. For example, combining... Figure 2 The operating voltage of component 1 to be powered is V1, so the first voltage conversion command sent to power conversion module 1 carries V1, enabling power conversion module 1 to convert the voltage of the board power supply to V1 to provide the operating voltage for component 1. Similarly, the operating voltage of component 2 to be powered is V2, so the first voltage conversion command sent to power conversion module 2 carries V2, enabling power conversion module 2 to convert the voltage of the board power supply to V2 to provide the operating voltage for component 2. Similarly, the first voltage conversion command sent to other power conversion modules carries the operating voltage of the component to be powered corresponding to that power conversion module.

[0058] On the other hand, the operating data corresponding to each power conversion module can be sent to the control module. Specifically, the operating data can include data such as input / output voltage, input / output current, input / output power, and temperature. The control module can determine whether the power conversion module is abnormal based on the operating data. For example, if the input / output voltage, input / output current, or input / output power of the power conversion module is zero, or the temperature is too high, such as exceeding a preset threshold, then the power conversion module can be determined to be abnormal. Specifically, if power conversion module 1 is abnormal, it can be identified as the target power conversion module, and control switch 1 can be identified as the target control switch. At this time, the power supply to the component to be powered corresponding to the target control switch is component 1. Therefore, the control module sends a conduction command to control switch 1 to turn it on, and at the same time, the control module sends a second voltage conversion command to the backup power conversion module. The second voltage conversion command sent by the control module to the backup power conversion module carries the operating voltage of the component to be powered corresponding to the target control switch. Therefore, the second voltage conversion command sent by the control module to the backup power conversion module carries the operating voltage V1 of component 1 to be powered. Therefore, at this time, the backup power conversion module can provide operating voltage for the components to be powered.

[0059] Based on the power supply system provided in this example, when one of the power conversion modules fails, the backup power conversion module can be controlled to supply power to the components corresponding to the failed power conversion module, so as to ensure the power supply stability of each component and improve the power supply stability of the power supply system.

[0060] Optional, Figure 3 A schematic diagram of the power supply system provided in the embodiments of this application. Figure 2 ,like Figure 3 As shown, the multiple components to be powered include a first central processing unit (CPU) component, a second CPU component, a controller component, a CXL interconnect component, a memory component, and an interface component.

[0061] In this scenario example, the Central Processing Unit (CPU) is the core of the power supply system's computation and control, serving as the final execution unit for information processing and program execution. The power supply system includes two CPU components: a first CPU component and a second CPU component. The controller component can be a Baseboard Management Controller (BMC) component, or a ComputeExpress Link (CXL) interconnect component, a component using a standard high-speed interconnect protocol. The memory component can be the power supply system's memory, such as a solid-state drive (SSD). The interface component can be a Universal Serial Bus (USB) component. Based on the power supply system provided in this example, the type of each component to be powered can be determined.

[0062] Optional, Figure 4 A schematic diagram of the power supply system provided in the embodiments of this application. Figure 3 ,like Figure 4 As shown, the multiple power conversion modules include: a first voltage regulator VR1, a second voltage regulator VR2, a first point-of-load power supply POL1, a second point-of-load power supply POL2, a third point-of-load power supply POL3, and a fourth point-of-load power supply POL4; the second terminal of the first voltage regulator VR1 is connected to the board power supply, and the third terminal of the first voltage regulator VR1 is connected to the first central processing unit (CPU) component; the second terminal of the second voltage regulator VR2 is connected to the board power supply, and the third terminal of the second voltage regulator VR2 is connected to the second CPU component; the second terminal of the first point-of-load power supply POL1 is connected to the board power supply, and the third terminal of the first point-of-load power supply POL1 is connected to the controller component; the second terminal of the second point-of-load power supply POL2 is connected to the board power supply, and the third terminal of the second point-of-load power supply POL2 is connected to the CXL interconnect component; the second terminal of the third point-of-load power supply POL3 is connected to the board power supply, and the third terminal of the third point-of-load power supply POL3 is connected to the memory component; the second terminal of the fourth point-of-load power supply POL4 is connected to the board power supply, and the third terminal of the fourth point-of-load power supply POL4 is connected to the interface component.

[0063] Based on the scenario example, power conversion modules 1 and 2 can be voltage regulators (VRs), so they are respectively the first voltage regulator VR1 and the second voltage regulator VR2. The CPU component typically operates within a voltage range of 0.8V-1.8V, so the first voltage regulator VR1 and the second voltage regulator VR2 can convert the board power supply voltage to a value within this range. Power conversion modules 3-6 can be point-of-load (POL) power supplies, specifically the first POL1, second POL2, third POL3, and fourth POL4. The BMC typically operates within a voltage range of 1V-1.6V, the CXL interconnect component typically operates within a voltage range of 1.2V-1.7V, the memory component typically operates within a voltage range of 2.97V-3.63V, and the interface component typically operates within a voltage range of 4.8V-5.2V. The first voltage regulator VR1 and the second voltage regulator VR2 can convert the voltage of the single-board power supply to 0.8V-1.8V. The first load point power supply POL1 can convert the voltage of the single-board power supply to 1V-1.6V. The second load point power supply POL2 can convert the voltage of the single-board power supply to 1.2V-1.7V. The third load point power supply POL3 can convert the voltage of the single-board power supply to 2.97V-3.63V. The fourth load point power supply POL4 can convert the voltage of the single-board power supply to 4.8V-5.2V.

[0064] Normally, each component to be powered operates at a reference voltage. Specifically, if the reference voltage for the first CPU component is 0.9V, the reference voltage for the second CPU component is 1V, the reference voltage for the BMC is 1.2V, the reference voltage for the CXL interconnect component is 1.54V, the reference voltage for the memory component is 3.3V, and the reference voltage for the interface component is 5V, then the first voltage regulator VR1 can convert the board power supply voltage to 0.9V, the second voltage regulator VR2 can convert the board power supply voltage to 1V, the first point-of-load power supply POL1 can convert the board power supply voltage to 1.2V, the second point-of-load power supply POL2 can convert the board power supply voltage to 1.54V, the third point-of-load power supply POL3 can convert the board power supply voltage to 3.3V, and the fourth point-of-load power supply POL4 can convert the board power supply voltage to 5V.

[0065] Based on the power supply system provided in this example, the voltage of the single-board power supply can be converted into the corresponding operating voltage of the component to be powered through various power conversion components.

[0066] Optional, Figure 5 A schematic diagram of the power supply system provided in the embodiments of this application. Figure 4 ,like Figure 5 As shown, multiple control switches include a first control switch S1, a second control switch S2, a third control switch S3, a fourth control switch S4, a fifth control switch S5, and a sixth control switch S6; the backup power conversion module includes a backup voltage regulator VR3 and a backup point-of-load power supply POL5; the second terminals of the backup voltage regulator VR3 and the backup point-of-load power supply POL5 are respectively connected to the single-board power supply; the first terminal of the first control switch S1 is connected to the third terminal of the backup voltage regulator VR3, the second terminal of the first control switch S1 is connected to the first central processing unit, and the control terminal of the first control switch S1 is connected to the second terminal of the control module; the first terminal of the second control switch S2 is connected to the third terminal of the backup voltage regulator VR3, the second terminal of the second control switch S2 is connected to the second central processing unit, and the control terminal of the second control switch S2 is connected to the second terminal of the control module; the third control switch... The first terminal of the third control switch S3 is connected to the third terminal of the backup load point power supply POL5; the second terminal of the third control switch S3 is connected to the controller assembly; and the control terminal of the third control switch S3 is connected to the second terminal of the control module. The first terminal of the fourth control switch S4 is connected to the second terminal of the backup load point power supply POL5; the second terminal of the fourth control switch S4 is connected to the CXL interconnect assembly; and the control terminal of the fourth control switch S4 is connected to the second terminal of the control module. The first terminal of the fifth control switch S5 is connected to the third terminal of the backup load point power supply POL5; the second terminal of the fifth control switch S5 is connected to the memory assembly; and the control terminal of the fifth control switch S5 is connected to the second terminal of the control module. The first terminal of the sixth control switch S6 is connected to the third terminal of the backup load point power supply POL5; the second terminal of the sixth control switch S6 is connected to the interface assembly; and the control terminal of the sixth control switch S6 is connected to the second terminal of the control module.

[0067] Based on the scenario example, the first control switch S1, the second control switch S2, the third control switch S3, the fourth control switch S4, the fifth control switch S5, and the sixth control switch S6 can be relays. They are closed and opened by receiving control commands from the control module, and an electrical connection is established when closed. For example, when the first control switch S1 is closed, the backup voltage regulator VR3 is connected to the first central processing unit component. The backup voltage regulator VR3 can convert the voltage of the single board power supply to 0.9V to power the first central processing unit.

[0068] Based on the power supply system provided in this example, the backup voltage regulator or backup load point power supply can be controlled by the control module to replace the target power conversion module and supply power to the corresponding components to be powered, thereby improving the power supply stability of the power supply system to each component to be powered.

[0069] Optional, Figure 6Flowchart of the power supply method provided in the embodiments of this application Figure 1 ,like Figure 6 As shown, a control module is applied to a power supply system as described in any of the preceding items, wherein the power supply system includes a single-board power supply, multiple components to be powered, multiple power conversion modules, at least one backup power conversion module, multiple control switches, and a control module; as shown Figure 6 As shown, the method includes:

[0070] S601. Send a first voltage conversion command to multiple power conversion modules respectively, so that the multiple power conversion modules convert the voltage of the single board power supply into the working voltage of the corresponding component to be powered, so as to supply power to the corresponding component.

[0071] Referring to the scenario example, the control module sends a first voltage conversion command to each power conversion module, and includes the required output voltage value in the first voltage conversion command sent to each power conversion module. For example, combining... Figure 2 The operating voltage of component 1 to be powered is V1, so the first voltage conversion command sent to power conversion module 1 carries V1, enabling power conversion module 1 to convert the voltage of the board power supply to V1 to provide the operating voltage for component 1. Similarly, the operating voltage of component 2 to be powered is V2, so the first voltage conversion command sent to power conversion module 2 carries V2, enabling power conversion module 2 to convert the voltage of the board power supply to V2 to provide the operating voltage for component 2. Similarly, the first voltage conversion command sent to other power conversion modules carries the operating voltage of the component to be powered corresponding to that power conversion module.

[0072] S602. Obtain operating data from multiple power conversion modules.

[0073] Based on the scenario example, the control module can obtain the operating data corresponding to each power conversion module. Specifically, the operating data can include data such as input and output voltage, input and output current, input and output power, and temperature.

[0074] S603. Determine whether there is an abnormal target power conversion module based on the operating data of multiple power conversion modules.

[0075] Based on the scenario example, the control module can determine whether the power conversion module is abnormal based on the corresponding operating data. For example, if the input / output voltage, input / output current, or input / output power of the power conversion module is zero, or if the temperature is too high, such as exceeding a preset threshold, then the power conversion module can be determined to be abnormal.

[0076] S604. When there is an abnormal target power conversion module, send a turn-on command to the target control switch corresponding to the target power conversion module to turn on the target control switch.

[0077] Based on the scenario example, if power conversion module 1 malfunctions, it can be identified as the target power conversion module, and control switch 1 as the target control switch. In this case, the component to be powered corresponding to the target control switch will be powered by component 1. Therefore, the control module sends a turn-on command to control switch 1 to turn it on.

[0078] S605. Send a second voltage conversion command to the backup power conversion module so that when the target control switch is turned on, the backup power conversion module converts the voltage of the single board power supply into the working voltage of the component to be powered corresponding to the target control switch based on the second voltage conversion command, so as to supply power to the component to be powered corresponding to the target control switch.

[0079] Based on the scenario example, the control module simultaneously sends a second voltage conversion command to the backup power conversion module. This second voltage conversion command carries the operating voltage of the component to be powered, corresponding to the target control switch. Therefore, the second voltage conversion command sent by the control module to the backup power conversion module carries the operating voltage V1 of component 1. Thus, the backup power conversion module can provide the operating voltage to the component to be powered.

[0080] Based on the power supply method provided in this example, when one of the power conversion modules malfunctions, the backup power conversion module can be controlled to supply power to the components corresponding to the malfunctioning power conversion module, so as to ensure the power supply stability of each component and improve the power supply stability of the power supply system.

[0081] Optional, Figure 7 Flowchart of the power supply method provided in the embodiments of this application Figure 2 The multiple components to be powered include a first central processing unit (CPU) component, a second CPU component, a controller component, a CXL interconnect component, a memory component, and an interface component. The first CPU component corresponds to a first power conversion module, the second CPU component corresponds to a second power conversion module, the controller component corresponds to a third power conversion module, the CXL interconnect component corresponds to a fourth power conversion module, the memory component corresponds to a fifth power conversion module, and the interface component corresponds to a sixth power conversion module.

[0082] Accordingly, such as Figure 7 As shown, S601 includes:

[0083] S701. Determine the first operating voltage corresponding to the first central processing unit component, and send a first voltage conversion instruction for the first operating voltage to the first power conversion module so that the first power conversion module converts the voltage of the single board power supply into the first operating voltage to supply power to the first central processing unit component.

[0084] Combined with scenario examples, Figure 5 In the example power supply system, the first power conversion module is a first voltage regulator VR1. The first operating voltage corresponding to the first central processing unit is a voltage value in the range of 0.8V-1.8V, such as 0.9V. Then, a first voltage conversion command carrying 0.9V is sent to the first voltage regulator VR1 so that the first voltage regulator VR1 converts the voltage of the single board power supply to 0.9V to supply power to the first central processing unit.

[0085] S702. Determine the second operating voltage corresponding to the second central processing unit component, and send a first voltage conversion instruction regarding the second operating voltage to the second power conversion module, so that the second power conversion module converts the voltage of the single-board power supply into the second operating voltage to supply power to the second central processing unit component.

[0086] Combined with scenario examples, Figure 5 In the example power supply system, the second power conversion module is a second voltage regulator VR2. The second operating voltage corresponding to the second central processing unit is a voltage value in the range of 0.8V-1.8V, such as 1V.

[0088] Combined with scenario examples, Figure 5 In the example power supply system, the controller component is a BMC component, and the third power conversion module is a first point-of-load power supply (POL1). The third operating voltage corresponding to the BMC component is a voltage value in the range of 1V-1.6V, for example, 1.2V. Then, a first voltage conversion command carrying 1.2V is sent to the first point-of-load power supply (POL1) so that the first point-of-load power supply (POL1) converts the voltage of the single-board power supply to 1.2V to supply power to the BMC.

[0089] S704.

[0090] Combined with scenario examples, Figure 5 In the example power supply system, the fourth power conversion module is the second point-of-load power supply POL2. The fourth operating voltage corresponding to the CXL interconnect component is a voltage value in the range of 1.2V-1.7V, such as 1.54V. Then, a first voltage conversion command carrying 1.54V is sent to the second point-of-load power supply POL2 so that the second point-of-load power supply POL2 converts the voltage of the single board power supply to 1.54V to supply power to the CXL interconnect component.

[0092] Combined with scenario examples, Figure 5 In the example power supply system, the fifth power conversion module is the third point-of-load power supply (POL3). The fifth operating voltage corresponding to the memory component is a voltage value within the range of 2.97V-3.63V, for example, 3.3V. Therefore, a first voltage conversion command carrying 3.3V is sent to the third point-of-load power supply (POL3) to convert the board power supply voltage to 3.3V to power the memory component.

Determine the sixth operating voltage corresponding to the interface component, and send the first voltage conversion command for the sixth operating voltage to the sixth power conversion module so that the sixth power conversion module converts the voltage of the single board power supply into the sixth operating voltage to supply power to the interface component.

[0094] Combined with scenario examples, Figure 5 In the example power supply system, the sixth power conversion module is the fourth point-of-load power supply (POL4). The sixth operating voltage corresponding to the interface component is a voltage value in the range of 4.8V-5.2V. For example, if it is 5V, a first voltage conversion command carrying 3.3V is sent to the fourth point-of-load power supply (POL4) to convert the voltage of the single-board power supply to 5V to supply power to the interface component.

[0095] Based on the control method provided in this example, by sending a first voltage conversion command carrying the operating voltage of the corresponding component to be powered to each power conversion module, it can be ensured that the voltage output by each power conversion module meets the operating requirements of the corresponding component to be powered, so as to ensure that each component to be powered can work normally.

[0098] Based on the scenario example, adjacent power conversion modules can be identified as mutually associated power conversion modules. That is, the first voltage regulator VR1 and the second voltage regulator VR2 are mutually associated power conversion modules, the first load point power supply POL1 and the second load point power supply POL2 are mutually associated power conversion modules, and the third load point power supply POL3 and the fourth load point power supply POL4 are mutually associated power conversion modules.

[0099] Therefore, if the target associated power conversion module is the first load point power supply POL1, then the target associated power conversion module is the second load point power supply POL2.

[0100] S802. Determine the first operating voltage range of the component to be powered corresponding to the target power conversion module.

[0101] Based on the scenario example, the component to be powered corresponding to the first load point power supply POL1 is the BMC component, so the first operating voltage range can be determined to be 1V-1.6V.

[0102] S803. Determine the second operating voltage range of the component to be powered corresponding to the target associated power conversion module.

[0103] Based on the scenario example, the component to be powered corresponding to the second load point power supply POL2 is the CXL interconnect component, so the second operating voltage range can be determined to be 1.2V-1.7V.

[0104] S804. Determine the same first target operating voltage range by using the first operating voltage range and the second operating voltage range.

[0105] Based on the scenario example, the first target operating voltage range is 1.2V-1.6V.

[0106] S805. Determine the target-associated control switch corresponding to the target-associated power conversion module.

[0107] Referring to the scenario example, if the target power conversion module is the first load point power supply POL1, and based on the aforementioned content, the control module will send a conduction command to the third control switch S3 corresponding to the first load point power supply POL1, so the third control switch S3 will close at this time. Simultaneously, the target associated control switch will be the fourth control switch S4.

[0108] S806. Send a turn-on command to the target control switch and the target associated control switch to turn on the target control switch and the target associated control switch.

[0111] In the scenario example, when the third control switch S3 and the fourth control switch S4 are both turned on, the second point-of-load power supply POL2 can simultaneously supply power to both the controller component and the CXL interconnect component. Therefore, at this time, the control module sends a second voltage conversion command (1.2V-1.6V) to the second point-of-load power supply POL2. In response to this command, the second point-of-load power supply POL2 converts the board power supply voltage to a voltage within the 1.2V-1.6V range, thus achieving the goal of simultaneously supplying power to both the controller component and the CXL interconnect component.

[0114] In the case of a scenario example, if the target associated power conversion module is the first load point power supply POL1, and only the backup load point power supply POL5 is used to power the controller components, then the target associated control switch is the fourth control switch S4. First, the conduction status of the fourth control switch S4 is monitored.

[0115] S902. If the target-associated control switch is turned on, a turn-on command is sent to the target-associated control switch to turn off the target-associated control switch.

[0116] In the scenario example, if the fourth control switch S4 is turned on, a disconnect command is sent to the fourth control switch S4. Disconnecting the fourth control switch S4 can avoid signal interference between the second load point power supply POL2 and the backup load point power supply POL5.

[0119] Based on the scenario example, when there is no abnormal target power conversion module, the overall efficiency of the power supply system should be considered first. The analysis can be performed on a set of power conversion modules and associated power conversion modules. If the efficiency of the power conversion module is E1 and the efficiency of the associated power conversion module is E2, then the total efficiency of the power conversion module and the corresponding associated power conversion module is E1+E2.

[0120] The efficiency E1 of the power conversion module depends on the power of the power conversion module, and the efficiency E2 of the associated power conversion module depends on the power of the associated power conversion module. When the total efficiency meets the preset condition and is maximized, the power of the power conversion module is determined as the first target power, and the power of the associated power conversion module is determined as the second target power.

[0121] S1002. Send a first target power operation command to the power conversion module so that the power conversion module operates at the first target power.

[0122] Based on the scenario example, the power conversion module operates at the first target power to ensure the optimal overall efficiency of the power conversion module and its corresponding associated power conversion modules.

[0123] S1003. Send a second target power operation command to the associated power conversion module so that the associated power conversion module operates at the second target power.

[0124] Based on the scenario example, the associated power conversion module operates at the second target power to ensure the optimal overall efficiency of the power conversion module and its corresponding associated power conversion module.

[0125] Based on the power supply method provided in this example, the power conversion module and associated power conversion module can operate at the power with optimal overall efficiency, thereby improving the overall operating efficiency of the power supply system.

[0126] Optional, Figure 11 Flowchart of the power supply method provided in the embodiments of this application Figure 6 ,like Figure 11 As shown, in S1001, determining the first target power of the power conversion module and the second target power of the associated power conversion module when the total efficiency of the power conversion module and the corresponding associated power conversion module meets the preset conditions includes:

Therefore, we can... Figure 12 The efficiency-current variation curves for each power conversion module are determined.

[0129] S1102. Based on the efficiency-current change curves of the power conversion module and the corresponding associated power conversion module, determine the first target current of the power conversion module and the second target current of the associated power conversion module when the total efficiency of the power conversion module and the corresponding associated power conversion module meets the preset conditions.

[0130] In a scenario example, if the power conversion module is the first point-of-load power supply (POL1), then the output voltage of POL1 is 1.2V. The first target current at optimal efficiency is determined based on the efficiency-current curve corresponding to 1.2V. Similarly, if the associated power conversion module of POL1 is the second point-of-load power supply (POL2), and the output voltage of POL2 is 1.54V, the second target current at optimal efficiency is determined based on the efficiency-current curve corresponding to 1.54V.

[0131] S1103. Obtain the first target operating voltage of the component to be powered corresponding to the power conversion module, and the second target operating voltage of the component to be powered corresponding to the associated power conversion module.

[0132] Based on the scenario example and the above content, we know that the first target operating voltage is 1.2V and the second target operating voltage is 1.54V.

[0133] S1104. The product of the first target current and the first target operating voltage is determined as the first target power corresponding to the power conversion module.

[0134] Based on the scenario example, power P=U×I, so the first target power of the first load point power supply POL1 can be determined according to the first target current and the first target operating voltage determined above.

[0135] S1105. The product of the second target current and the second target operating voltage is determined as the second target power corresponding to the associated power conversion module.

[0136] Based on the scenario example, power P=U×I, so the second target power of the second load point power supply POL2 can be determined according to the second target current and the second target operating voltage determined above.

[0137] Based on the power supply method provided in this example, the target current can be determined by the efficiency-current change curves at each voltage, and then the target power can be determined. This allows for the accurate determination of the target power corresponding to each power conversion module when the power supply system has the highest efficiency.
