For example, the power supply voltage is higher than the voltage required by the power supply device, that is, the power supply voltage is higher than the voltage required by the power supply device. However, continuously powering the power supply device with a voltage higher than the voltage required by the power supply device will lead to energy waste and accelerate the aging of the power supply device. Therefore, how to reduce power consumption, improve the energy efficiency of power supply devices, and extend the life of power supply devices has become an urgent problem to be solved.

[0040] To facilitate understanding, the main terms involved in the embodiments of the present application are first explained.

[0041] Power Supply Unit (PSU): A power supply mounted on a printed circuit board. Power supply modules are used to provide power to various devices in a computer system. Devices include, but are not limited to, application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field-programmable gate arrays (FPGAs), and other digital or analog loads.

[0042] Voltage: It can also be called potential difference or electric potential difference. It is a physical quantity that measures the energy difference caused by different electric potentials of unit charges in an electrostatic field.

[0043] Voltage Regulator Module (VRM): used to control the DC-DC conversion circuit on the motherboard to provide stable voltage for electrical devices. The power supply circuit formulated according to the VRM standard can meet the requirements of different processors, reduce the complexity of manual intervention, and simplify the voltage control design of the voltage stabilization circuit.

[0044] Power: A physical quantity used to indicate the work done by an object in a unit of time, that is, power represents the speed of an object doing work. The unit of power is watt (W), abbreviated as W. Power can be represented by P, P = W / t, W represents work, the unit of work is joule, t represents unit time, and the unit of t is second (S).

[0045] Energy efficiency: Also known as energy efficiency, it refers to the ratio of the amount of energy that works to the amount of energy actually consumed in energy utilization. The higher the energy efficiency, the more energy-saving it is. For example, if an air conditioner can consume less electricity to provide a stronger cooling effect, it means that the air conditioner is more energy-saving and has a higher energy efficiency.

[0046] Aging: refers to the phenomenon that materials gradually deteriorate and lose their value due to the combined effects of internal and external factors. Aging is an irreversible change. For example, during the use of polymer materials, due to the combined effects of environmental factors such as heat, oxygen, water, light, microorganisms, and chemical media, the chemical composition and structure of polymer materials undergo a series of changes, and the physical properties also deteriorate accordingly, such as hardening, stickiness, brittleness, discoloration, and loss of strength. These changes and phenomena are called aging.

[0047] During the operation of computer equipment, the electronic components in the computer equipment also age. The aging of electronic components can lead to the performance degradation of computer equipment (such as the decrease of the capacitance value of capacitors and the increase of the resistance value), increase of the failure rate, and even the failure of electronic components (such as the failure of transistors and diodes). Therefore, the aging of electronic components is of great significance to improving the reliability and stability of computer equipment.

[0048] The causes of aging of electronic components include the following.

[0049] 1. Changes in the internal structure of electronic components.

[0050] As electronic components are used for a longer time, their internal structures change, and these changes can affect their performance, such as metal surface oxidation, dielectric aging, loose solder joints, etc. Changes in the internal structures of electronic components can cause the temperature of electronic components to rise, affecting the stability of electronic equipment.

[0051] 2. Temperature changes and humidity changes.

[0052] Temperature change and humidity change are one of the important factors in the aging of electronic components. In a high temperature and high humidity environment, the internal structure of electronic components will change, leading to the aging of electronic components.

[0053] 3. Voltage changes and current changes.

[0054] During the operation of computer equipment, voltage changes and current changes can also cause electronic components to age. For example, electronic components that are exposed to high voltage and high current for a long time are prone to damage.

[0055] In order to solve the problem of continuously supplying power to electrical devices at a voltage higher than that required by the electrical devices, resulting in energy waste and accelerated aging of the electrical devices. The present application provides a power supply method for a computer system, that is, when the power supply circuit supplies power to the electrical devices at a first voltage, a sensor in the computer system collects power supply parameters indicating the degree of aging of the computer system, controls the power supply circuit to output a second voltage according to the power supply parameters, and supplies power to the electrical devices at the second voltage. By estimating the degree of aging of the computer system in real time, the supply voltage (supply voltage) of the electrical devices is accurately and dynamically controlled in real time according to the degree of aging of the computer system, thereby avoiding continuously supplying power to the electrical devices at a fixed voltage, thereby effectively reducing power consumption, improving the energy efficiency of electrical devices, delaying the life of electrical devices, and improving the reliability and stability of computer equipment.

[0056] The power supply method for the computer system provided by the present application is described in detail below with reference to the accompanying drawings. Figure 1 A schematic diagram of a computer system provided in this application. Figure 1 As shown, the computer system 100 includes a voltage control circuit 110, an electrical device 120, and a power supply circuit 130. The voltage control circuit 110, the electrical device 120, and the power supply circuit 130 are connected to each other. For example, the voltage control circuit 110, the electrical device 120, and the power supply circuit 130 are connected to each other through a bus. The bus may include a path for transmitting information between the above components (such as the voltage control circuit 110, the electrical device 120, and the power supply circuit 130). For example, the electrical device 120 feeds back real-time power supply parameters to the voltage control circuit 110, and the voltage control circuit 110 controls the power supply circuit 130 to provide the power supply voltage to the electrical device 120. The bus may be a Peripheral Component Interconnect Express (PCIe) bus, an I2C bus, a Power Management Bus (PMBus) bus, an Adaptive Voltage Scaling Bus (AVS bus), etc.

[0057] The electrical device 120 includes electronic components used for data processing or communication in a computer system, such as a processor, a memory and a memory unit (also referred to as a main memory unit), a network adapter (such as a network interface card (NIC), an intelligent network interface card (iNIC)), etc. The processor may be a central processing unit (CPU), a graphics processing unit (GPU), a data processing unit (DPU), a neural processing unit (NPU), an embedded neural-network processing unit (NPU), etc., which are used for data processing.

[0058] Optionally, the electrical device 120 may also refer to electronic components in chips such as processors, memories, and memory units. Alternatively, the electrical device 120 may be a circuit board powered by multiple power supplies. The present application does not limit the specific form of the electrical device. The electrical device may also be referred to as an electrical unit.

[0059] For ease of description, the following embodiments are described by taking the electrical device 120 as a CPU as an example.

[0060] The power supply circuit 130 is used to adjust the voltage provided by the power module to supply power to the power-consuming device 120. The power module can be arranged in the computer system 100 or outside the computer system 100.

[0061] In some embodiments, Figure 2 As shown, the power supply circuit 130 includes a voltage regulation module 131 , a voltage conversion module 132 and a voltage filtering module 133 .

[0062] The voltage regulating module 131 is used to control the voltage converting module 132 to provide a stable DC voltage for the electrical device 120 .

[0063] The voltage conversion module 132 is used to convert the DC voltage provided by the voltage regulation module 131 into the DC voltage required by the electrical device 120. The voltage conversion module 132 may include power field effect transistors and inductors. The number of power field effect transistors and inductors included in the voltage conversion module 132 is not limited.

[0064] The voltage filter module 133 is used to filter out interference components such as clutter and noise in the voltage signal input to the electrical device 120, output a stable DC voltage signal, and ensure the normal operation of the electrical device 120. Wherein, the voltage filter module 133 may include capacitors and inductors. The filter network composed of capacitors and inductors filters out the high-frequency components in the voltage signal and retains the output of low-frequency components. The capacitor can filter out the high-frequency noise in the voltage signal through the accumulation and release of the voltage, while the inductor can pass the low-frequency components through its self-inductance, thereby avoiding voltage instability. According to specific design requirements, a single voltage filter module or a plurality of voltage filter modules can be used in combination to achieve better filtering effect. For example, the voltage filter module includes a low-pass filter, a band-pass filter and a band-stop filter.

[0065] The voltage control circuit 110 is used to monitor the aging degree of the computer system 100 in real time, and dynamically control the power supply voltage provided by the power supply circuit 130 to the electrical device 120 in real time according to the aging degree of the computer system 100 .

[0066] In some embodiments, since the reasons for the aging of electronic components in a computer system are different, resulting in different degrees of aging of electronic components, the computer system can be divided into multiple ranges or multiple areas, and the aging degrees of different ranges or different areas can be monitored respectively. Thus, the power supply voltage of the electrical components can be accurately controlled in real time and dynamically, reducing power consumption, improving the energy efficiency of the electrical components, and extending the life of the electrical components, thereby improving the reliability and stability of computer equipment.

[0067] The voltage control circuit 110 can monitor the aging degree of different ranges in the computer system 100, and control the power supply voltage provided by the power supply circuit 130 to the electrical device 120 according to the aging degree of different ranges. The aging degree of different ranges can refer to the aging degree of different ranges in the power supply path. The power supply path can refer to the path composed of the power supply circuit to the electrical device. The power supply path includes at least the power supply circuit and the electrical device.

[0068] For example, the voltage control circuit 110 monitors the aging degree of the electrical device 120 , and uses the aging degree of the electrical device 120 as the aging degree of the computer system 100 , and dynamically controls the power supply voltage provided by the power supply circuit 130 to the electrical device 120 in real time.

[0069] For another example, the voltage control circuit 110 also monitors the aging degree of the power supply circuit 130 , and uses the aging degree of the power supply circuit 130 as the aging degree of the computer system 100 , and dynamically controls the power supply voltage provided by the power supply circuit 130 to the electrical device 120 in real time.

[0070] For another example, the voltage control circuit 110 dynamically controls the supply voltage provided by the power supply circuit 130 to the power device 120 in real time based on the aging degree of the power device 120 and the aging degree of the power supply circuit 130 as the aging degree of the computer system 100 .

[0071] For example, Figure 2 As shown, the voltage control circuit 110 includes a controller 111 and at least one sensor 112. The controller 111 is connected to the power supply circuit 130 and the at least one sensor 112 respectively. The at least one sensor 112 can be arranged around the power supply circuit 130 and the electrical device 120.

[0072] The controller 111 may be other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA), systems on chip (SoC), complex programmable logical devices (CPLD) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or a microcontroller unit (MCU) or any conventional processor, etc.

[0073] At least one sensor 112 is used to collect power supply parameters of the computer system 100, and the power supply parameters are used to indicate the aging degree of the computer system 100. For example, at least one sensor 112 is used to monitor the power supply parameters of the power supply circuit 130 and the power supply parameters of the electrical device 120.

[0074] The controller 111 is used to control the output voltage of the power supply circuit 130 according to the power supply parameters, and to supply power to the electrical device 120 with the output voltage of the power supply circuit 130 .

[0075] Optionally, the voltage control circuit 110 further includes a memory 113. The memory 113 is used to store the power supply parameters collected by the sensor 112 and the current voltage of the electrical device 120. For example, the memory 113 may be a flash memory, an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a hard disk, or other storage media.

[0076] For example, Figure 3 As shown, it is assumed that the electrical device 120 is a CPU, the controller 111 is an MCU, the voltage conversion module 132 includes a voltage output device and an inductor, and the voltage filtering module 133 includes a capacitor. The voltage output device can be implemented by a driver and metal oxide silicon field effect transistor module (Driver and Metal Oxide Silicon Field Effect Transistors Module, DRMOS), which is a voltage regulator module (VRM) using an external pulse-width modulation (PWM) controller in a buck configuration.

[0077] A sensor 1 is arranged around the DRMOS, a sensor 2 is arranged around the capacitor, and a sensor 3 is arranged inside the CPU.

[0078] The controller 111 is connected to the sensor 1 , the sensor 2 , and the sensor 3 respectively through the I2C bus.

[0079] The controller 111 is connected to the voltage regulation module 131 via a power management bus (PMBus).

[0080] The sensor 1 is used to collect power supply parameters of the electronic components included in the power supply circuit 130. For example, the sensor 1 collects the temperature, humidity and power of the DRMOS.

[0081] Sensor 2 is a temperature sensor, which is used to collect the average temperature of the board-level filter capacitor. For example, sensor 2 collects the board-level filter capacitor in a preset period of time and calculates the average temperature of the board-level filter capacitor.

[0082] The sensor 3 is used to collect the power and temperature of the electrical device 120 when it is running.

[0083] Optionally, the electrical device 120 feeds back the current voltage of the electrical device 120 to the voltage regulating module 131. This allows the controller 111 to obtain the current voltage of the electrical device 120 and the power supply parameters collected by the sensor, and dynamically control the power supply voltage provided by the power supply circuit 130 to the electrical device 120 in real time. The current voltage may be a voltage peak value under the actual service state of the electrical device.

[0084] The present application does not limit the arrangement of the sensors and the number of sensors.

[0085] In some embodiments, the sensor may be connected to the device, or the sensor may not be connected to the device. For example, the temperature sensor and the humidity sensor may not be connected to the device, but may be arranged around the device to collect the temperature and humidity in the environment around the device. For another example, the power sensor is connected to the device to collect the power of the device.

[0086] Optionally, the sensor may be disposed in the device or outside the sensor. For example, the processor includes a sensor, and the sensor inside the processor is reused to collect the power, temperature and humidity of the processor.

[0087] In some embodiments, each electronic component and electrical device in the power supply circuit can share a sensor, and the sensor is used to collect power supply parameters of each electronic component and electrical device in the power supply circuit. For example, a temperature sensor is used to collect the temperature of each electronic component and electrical device in the power supply circuit.

[0088] Alternatively, each electronic component and electrical device in the power supply circuit is connected to a sensor, and each sensor collects the power supply parameters of the device connected to it. For example, each electronic component in the power supply circuit is connected to a power sensor to collect the power of the electronic component in the power supply circuit; and the electrical device is connected to a power sensor to collect the power of the electrical device.

[0089] Alternatively, the sensor shared by each electronic component and electrical device in the power supply circuit can be a comprehensive sensor that can collect power supply parameters such as temperature, humidity, and power.

[0090] The present application does not limit the connection method between the power supply circuit and the electrical device, nor the number of electrical devices supplied by the power supply circuit. One power supply circuit can be connected to one or more electrical devices to supply power to one or more electrical devices. In addition, the present application does not limit the number of voltage control circuits, nor the number of sensors included in the voltage control circuit. One voltage control circuit can be set for each power supply circuit and electrical device, or one voltage control circuit can be set for multiple power supply circuits and electrical devices.

[0091] For example, Figure 4 As shown in (a), the three power supply circuits are respectively connected to an electrical device. Each power supply circuit supplies power to the electrical device to which it is connected. Power supply circuit 1 is connected to electrical device 1 to supply power to the electrical device 1 to which it is connected. Voltage control circuit 1 is respectively connected to power supply circuit 1 and electrical device 1. Voltage control circuit 1 is used to monitor the aging degree of electrical device 1 in real time, and dynamically control the supply voltage provided by power supply circuit 1 to electrical device 1 in real time according to the aging degree of electrical device 1. The explanation of voltage control circuit 2 and voltage control circuit 3 refers to the explanation of voltage control circuit 1 and will not be repeated here.

[0092] like Figure 4 As shown in (b), the voltage control circuit 1 is respectively connected to the power supply circuit 1, the power supply circuit 2, the power supply circuit 3, the electric device 1, the electric device 2 and the electric device 3. The voltage control circuit 1 is used to monitor the aging degree of the electric device 1, the aging degree of the electric device 2 and the aging degree of the electric device 3 in real time, and dynamically control the power supply voltage provided by the power supply circuit 1 to the electric device 1 according to the aging degree of the electric device 1, dynamically control the power supply voltage provided by the power supply circuit 2 to the electric device 2 according to the aging degree of the electric device 2, and dynamically control the power supply voltage provided by the power supply circuit 3 to the electric device 3 according to the aging degree of the electric device 3.

[0093] like Figure 4 As shown in (c), one power supply circuit is connected to three electrical devices. Among them, the multiple electrical devices connected to one power supply circuit may belong to the same module or different modules. For example, the power supply circuit 1 is connected to different electronic components in the processor 1, and the power supply circuit 1 can provide the required voltages to different electronic components in the processor 1. The voltage control circuit 1 is connected to the power supply circuit 1 and the processor 1. The voltage control circuit 1 controls the power supply voltage provided by the power supply circuit 1 to different electronic components in the processor 1 in real time and dynamically according to the aging degree of different electronic components in the processor 1. Optionally, since the power supply circuit 1 supplies power to different electronic components in the processor 1, when the voltage control circuit 1 adjusts the voltage of each electronic component, it controls the power supply voltage provided by the power supply circuit 1 to the electronic component in real time and dynamically according to the aging degree of the electronic component and the aging degree of the power supply circuit 1.

[0094] Figure 1 In the example, a computer system 100 including a voltage control circuit 110, an electrical device 120 and a power supply circuit 130 is taken. Here, the voltage control circuit 110 and the electrical device 120 are respectively used to indicate a type of device or equipment. In a specific embodiment, the number of each type of device or equipment can be determined according to business requirements.

[0095] Combine the following Figure 5 The present application provides a method for supplying power to a computer system. Figure 5 Here we use Figure 1 The computer system shown in the figure uses an example in which the voltage control circuit 110 controls the power supply circuit 130 to supply power to the power-consuming device 120 .

[0096] Step 510: When the power supply circuit supplies power to the electrical device at a first voltage, the controller obtains a power supply parameter collected by at least one sensor.

[0097] The first voltage refers to the current voltage of the electrical device or the real-time voltage supplied to the electrical device. When the power supply circuit supplies power to the electrical device for the first time, the first voltage may refer to the real-time voltage that the power supply circuit initially supplies power to the electrical device. For example, the power supply circuit may supply power to the electrical device based on the initial voltage, and the first voltage is the initial voltage. The initial voltage may be a system default voltage or a pre-configured voltage. Alternatively, the initial voltage may refer to the voltage required when the electrical device is not aged. For another example, the power supply circuit may supply power to the electrical device based on the initial voltage and the first voltage margin value, and the first voltage may be the sum of the initial voltage and the first voltage margin value. Thus, an additional margin voltage is provided to the electrical device to ensure the voltage required by the electrical device, thereby avoiding the phenomenon that the performance of the electrical device is reduced, and the reliability and stability are reduced due to the voltage supplied by the power supply circuit being lower than the voltage required by the electrical device.

[0098] After the power supply circuit supplies power to the electrical device for the first time, the controller can obtain the power supply parameters collected by at least one sensor, and control the voltage of the power supply circuit to the electrical device according to the power supply parameters, that is, adjust the voltage of the power supply to the electrical device according to the power supply parameters. Then, after the power supply circuit supplies power to the electrical device for the first time, the first voltage can refer to any real-time voltage after the power supply circuit supplies power to the electrical device.

[0099] The power supply parameters are used to indicate the aging degree of the computer system. The controller obtains the power supply parameters collected by the sensor and uses the power supply parameters collected by the sensor to sense the aging degree of the computer system.

[0100] Since the reasons for the aging of the computer system include changes in the internal structure, temperature, humidity, voltage and current of the electronic components in the computer system, the power supply parameters include but are not limited to: humidity, temperature, power, voltage, current, working time, etc. Humidity can refer to the temperature of the electronic component itself or the temperature of the external environment of the electronic component. Temperature can refer to the temperature of the electronic component itself or the temperature of the external environment of the electronic component. Power can refer to the power of the electronic component. Voltage can refer to the current voltage of the electronic component. Current can refer to the current current of the electronic component. Working time can refer to the cumulative power-on time of the electronic component. That is, there is no need to time the power-off time of the electronic component, only the power-on time of the electronic component needs to be timed, and the working time can refer to the total power-on time of the electronic component.

[0101] For example, the controller obtains power supply parameters collected by a first sensor set in a cycle of the electrical device, where the power supply parameters include a first power supply parameter of the electrical device collected by the first sensor.

[0102] For another example, the controller obtains power supply parameters collected by a second sensor set in a power supply circuit cycle, and the power supply parameters include second power supply parameters of the power supply circuit collected by the second sensor. For example, the power supply circuit includes a voltage regulation module, a voltage conversion module, and a voltage filtering module. The second power supply parameters of the power supply circuit include power supply parameters of the voltage regulation module, power supply parameters of the voltage conversion module, and power supply parameters of the voltage filtering module.

[0103] Optionally, the temperature in the power supply parameter may include at least one of the temperature of the electrical device, the temperature of the power supply circuit, the temperature of the external environment of the electrical device, or the temperature of the external environment of the power supply circuit.

[0104] Optionally, the humidity in the power supply parameter may include at least one of the humidity of the electrical device, the humidity of the power supply circuit, the humidity of the external environment of the electrical device, or the humidity of the external environment of the power supply circuit.

[0105] Step 520: The controller controls the power supply circuit to output a second voltage according to the power supply parameter.

[0106] The controller adjusts the first voltage according to the power supply parameters to obtain the second voltage, that is, adjusts the current voltage of the electrical device according to the power supply parameters to obtain the second voltage, and controls the power supply circuit to output the second voltage. The second voltage refers to the adjusted voltage. Since the longer the working time of the electrical device, the more obvious the aging phenomenon of the electrical device, and the higher the voltage required by the electrical device, the second voltage adjusted according to the power supply parameters can be greater than the first voltage. It can be understood that the first voltage adjusted by the controller for the i-th time is the second voltage obtained after the i-1-th adjustment.

[0107] The following is an example of how to adjust the power supply voltage of an electrical device.

[0108] In a first approach, a controller obtains a voltage adjustment value corresponding to a power supply parameter, and adjusts the first voltage according to the voltage adjustment value to obtain a second voltage.

[0109] The controller obtains the aging-voltage correspondence, queries the aging-voltage correspondence according to the power supply parameters collected by the sensor, determines the voltage adjustment value corresponding to the power supply parameters in the correspondence, and adjusts the first voltage according to the voltage adjustment value to obtain the second voltage.

[0110] The aging-voltage correspondence is used to indicate the correspondence between the aging data and the voltage adjustment value. The aging data includes data related to the aging cause. For example, the aging data includes at least one of temperature, humidity, power, voltage, or working time.

[0111] The aging-voltage correspondence relationship may be stored in a memory in a computer system or in a memory in the voltage control circuit described in the above embodiment.

[0112] For example, the aging-voltage correspondence is stored for device types. The device types include, but are not limited to, processors, memories, network cards, etc. The memory can store the aging-voltage correspondence of the processor, the aging-voltage correspondence of the memory, and the aging-voltage correspondence of the network card.

[0113] For another example, the aging-voltage correspondence relationship is stored for the device model. For different models of the same device, the memory can store the aging-voltage correspondence relationship of the same model of the device.

[0114] The memory is also used to store the power supply parameters collected by the sensor. For example, the memory stores the power supply parameters of each electronic component in the computer system collected by the sensor. The power supply parameters of the electronic components are used to indicate the working state of the electronic components, and the aging degree of the electronic components is estimated based on the power supply parameters of the electronic components.

[0115] The memory is also used to store the current voltage of the electrical device, that is, the first voltage of the electrical device, so that the controller can control the power supply circuit to output the second voltage according to the power supply parameters.

[0116] This application does not limit the storage method of the aging-voltage correspondence relationship and the power supply parameter method.

[0117] For example, the aging-voltage correspondence and the power supply parameters are stored in a database manner. For another example, the aging-voltage correspondence and the power supply parameters are stored in a list manner.

[0118] For example, Figure 6As shown in (a), the power supply parameters include the working time and current voltage of the electrical device, as well as the aging data of the electrical device 1 collected by the sensor, and the aging data includes the temperature, humidity and power collected at multiple times. Figure 6 (b) is a schematic diagram of the aging-voltage correspondence relationship. Working time refers to the working time of the electrical device. Current voltage refers to the current voltage of the electrical device. Device 1 may refer to the aging data of the electrical device. Device 2 may refer to the aging data of the power supply circuit.

[0119] Optionally, the power supply parameters and corresponding relationships may be recorded in a table for each device, as shown in Table 1 and Table 2.

[0120] Table 1

[0121]

[0122] As can be seen from Table 1, the power supply parameters of the electrical device 1 are recorded, including working time, current voltage, temperature, humidity and power. The power supply parameters of the electrical device 1 indicate the aging degree of the electrical device 1. The longer the working time of the electrical device 1, the more obvious the aging phenomenon of the electrical device 1, and the higher the voltage of the electrical device 1. For example, if t2 is greater than t1, then V2 is greater than V1. Among them, when the working time of the electrical device 1 is T1, the power supply parameters collected at time t1 are: the current voltage of the electrical device 1 is V1, the temperature is T1℃, the humidity is H1, and the power is P1.

[0123] Table 2

[0124]

[0125] As can be seen from Table 2, the aging-voltage correspondence of the electrical device 1 is recorded, including the correspondence between the working time, the power supply parameters and the voltage adjustment value. For example, when the working time of the electrical device 1 is 100 hours and the power supply parameters collected by the sensor include temperature 1, humidity 1 and power 1, the voltage adjustment value is 1mv.

[0126] The aging-voltage correspondence relationship can be obtained based on an empirical value of the relationship between the aging process of the electrical device and the required voltage. For example, the relationship between the aging process of the electrical device and the required voltage can be obtained through testing.

[0127] It should be noted that Table 1 only illustrates the storage form of the corresponding relationship in the storage device in the form of a table, and does not limit the storage form of the corresponding relationship in the storage device. Of course, the storage form of the corresponding relationship in the storage device can also be stored in other forms, and this embodiment does not limit this.

[0128] For example, assuming that the power supply circuit supplies power to the electrical device with a first voltage, the first voltage is the sum of the initial voltage required by the electrical device and the first voltage margin value. For example, V0=V-init+VA, where V0 represents the first voltage, V-init represents the initial voltage, and VA represents the first voltage margin value.

[0129] The controller obtains the power supply parameters of the electrical device and the power supply parameters of the power supply circuit collected by the sensor, determines the first voltage adjustment value according to the power supply parameters of the electrical device, and determines the second voltage adjustment value according to the power supply parameters of the power supply circuit. The voltage adjustment value of the first voltage adjusted by the controller includes the first voltage adjustment value and the second voltage adjustment value. For example, V-ex=V-ex-device 1+V-ex-device 2+…, wherein V-ex represents the voltage adjustment value, V-ex-device 1 represents the voltage adjustment value of device 1, V-ex-device 2 represents the voltage adjustment value of device 2, and V-ex-device 1, V-ex-device 2, etc. can be obtained by looking up the table. Device 1 is an electronic component in the electrical device. Device 2 can be an electronic component in the power supply circuit.

[0130] The controller obtains an adjusted voltage according to the voltage adjustment value and the initial voltage, and compares the adjusted voltage with the first voltage.

[0131] When the adjusted voltage is greater than the first voltage, it indicates that the first voltage cannot meet the voltage requirement of the electrical device and the power supply voltage of the electrical device needs to be increased. For example, the adjusted voltage and the second voltage margin value can be determined as the second voltage, that is, the power supply circuit supplies power to the electrical device at the second voltage.

[0132] When the adjusted voltage is less than or equal to the first voltage, it means that the first voltage meets the voltage requirement of the electrical device, and the power supply voltage of the electrical device may be increased or not. For example, the adjusted voltage and the second voltage margin value may be determined as the second voltage, that is, the power supply circuit supplies power to the electrical device at the second voltage.

[0133] For example, V1=Vinit+V-ex, V1 represents the adjusted voltage, V'=V0-V1=V-init+VA-Vinit+V-ex=VAV-ex, V' represents the difference between the adjusted voltage and the first voltage, if the difference is greater than 0, it means that the first voltage meets the voltage requirement of the electrical device, if the difference is less than or equal to 0, it means that the first voltage cannot meet the voltage requirement of the electrical device. VA represents the first voltage margin value.

[0134] Optionally, the controller adjusts the first voltage according to the voltage adjustment value corresponding to the power supply parameter to obtain an adjusted voltage; and obtains the second voltage according to the adjusted voltage and the second voltage margin value. Thus, it is ensured that the power supply voltage meets the voltage requirements of the electrical device. The second voltage margin value may be the same as or different from the first voltage margin value.

[0135] For example, when the difference between the adjusted voltage and the first voltage is less than the second voltage margin value, the second voltage is obtained according to the adjusted voltage and the second voltage margin value. For example, V'<=VB, V2=Vinit+V-ex+VB. V2 represents the second voltage. VB is the second voltage margin value.

[0136] In a second method, the controller predicts the voltage adjustment value or the second voltage based on the neural network model. For example, the neural network model is trained based on the empirical value of the relationship between the aging process of the electrical device and the required voltage, so that the neural network model has the function of adjusting the power supply voltage according to the power supply parameters. The obtained power supply parameters are input into the neural network model, and the voltage adjustment value is output. Alternatively, the obtained power supply parameters are input into the neural network model, and the second voltage is output.

[0137] In a third mode, the controller controls the power supply circuit to output the second voltage according to external parameters and power supply parameters. The external parameters include at least one of power supply demand, power supply voltage change trend or life cycle.

[0138] For example, the controller adjusts the first voltage according to the power supply parameter to obtain the second voltage, and determines whether the second voltage meets the power supply requirement. When the second voltage meets the power supply requirement, the power supply circuit is controlled to supply power to the electrical device with the second voltage. When the second voltage does not meet the power supply requirement, the power supply circuit is controlled to supply power to the electrical device with the voltage indicated by the power supply requirement.

[0139] For another example, the controller uses a neural network model to predict the second voltage based on power supply parameters, supply voltage change trends, and the expected life of the electrical device. The supply voltage change trend can be estimated based on the historical supply voltage of the electrical device, and the required voltage can be supplied to the electrical device in advance to ensure stable power supply to the electrical device. The expected life of the electrical device can refer to the product service life of the electrical device. A higher supply voltage can be provided to the electrical device in the later stage of its product service life so that the electrical device can operate stably.

[0140] Step 530: The power supply circuit supplies power to the electrical device at the second voltage.

[0141] For example, the power supply circuit includes a voltage regulating module, a voltage conversion module and a voltage filtering module. The voltage regulating module controls the voltage conversion module to provide a stable second voltage for the electrical device. The voltage conversion module converts the DC voltage provided by the voltage regulating module into the second voltage required by the electrical device. The voltage filtering module filters out interference components such as clutter and noise in the second voltage input to the electrical device, and outputs a stable second voltage to ensure the normal operation of the electrical device.

[0142] It should be noted that, when the power supply circuit is controlled to supply power to the electrical device according to the power supply method provided by the present application, the electrical device is powered at the initial voltage in the early stage of the life cycle of the electrical device, and the power supply voltage in the early stage of the life cycle of the electrical device is lower than the power supply voltage of the electrical device powered at a fixed voltage, so as to avoid powering the electrical device with a voltage higher than the voltage required by the electrical device, which will lead to waste of electric energy and accelerate the aging of the electrical device. In addition, during the entire life cycle of the electrical device, the aging degree of the electrical device is evaluated, and the power supply voltage of the electrical device is accurately controlled in real time and dynamically according to the aging degree of the electrical device, so as to ensure that the power supply voltage of the electrical device meets the required voltage of the electrical device, and the power supply voltage of the non-electrical device is at a higher voltage. The power supply voltage at the end of the life cycle of the electrical device can be lower than the power supply voltage of the electrical device powered at a fixed voltage. For example, if the aging degree of any device in the power supply circuit and the electrical device is lower than the estimated aging degree, including but not limited to the power not being at full load, the temperature of the device being lower than the estimated temperature, etc., the power supply voltage at the end of the life cycle of the electrical device can be lower than the power supply voltage of the electrical device powered at a fixed voltage. Alternatively, the power supply voltage at the end of the life cycle of the electrical device can be equal to the power supply voltage of the electrical device at a fixed voltage. Thus, by optimizing the power supply voltage during the life cycle of the electrical device, the power consumption can be effectively reduced, the energy efficiency of the electrical device can be improved, the life of the electrical device can be extended, and the reliability and stability of the computer equipment can be improved.

[0143] Figure 7 A flowchart of another method for powering a computer system provided in the present application.

[0144] The power supply circuit supplies power to the electrical device with the initial voltage, and the electrical device is powered on (step 710). The controller obtains the power supply parameters collected by the sensor (step 720). The power supply parameters stored in the system are updated according to the power supply parameters collected by the sensor (step 730). The controller determines the adjusted voltage according to the power supply parameters (step 740). It is determined whether the adjusted voltage meets the safety threshold (such as the second voltage margin value mentioned above) (step 750). If the adjusted voltage meets the safety threshold, the power supply circuit is controlled to supply power to the electrical device with the adjusted voltage (step 760), the adjusted voltage is stored (step 770), and step 720 is continued; if the adjusted voltage does not meet the safety threshold, step 720 is continued. Alternatively, the adjusted voltage is increased, for example, the adjusted voltage is added to the second voltage margin value to obtain the second voltage, and the electrical device is powered with the second voltage.

[0145] For example, assuming that the initial voltage of the electrical device is 1.0V, the power supply voltage V0=1.15V provided by the power supply circuit to the electrical device in the traditional solution. In the solution provided by the present application, the power supply circuit provides a power supply voltage V0=1.01V to the electrical device, and then gradually increases the power supply voltage as the power supply circuit and the electrical device age. At the end of the life cycle of the electrical device, the power supply voltage of the electrical device can reach V0=1.13V. Compared with the traditional solution, the power supply voltage is reduced by an average of 80mV during the life cycle of the electrical device, which is equivalent to a 7% improvement in the power supply energy efficiency of the electrical device.
