Description

[0001] This application claims priority to Chinese patent application No. 202010798179.5 filed on August 11, 2020, entitled “A method for dynamically adjusting the power supply load balancing ratio to improve efficiency”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of power supply technology, and in particular to a method, device and related equipment for controlling the output power of a power supply. Background Art

[0003] At present, the power consumption of network equipment such as servers is getting higher and higher. In order to meet the needs of high-power network equipment, multiple power supplies are configured for such network equipment, and these multiple power supplies jointly provide power to the network equipment. In the related art, these multiple power supplies are controlled to supply power to the network equipment according to the same output power, so that these multiple power supplies share the power consumption of the network equipment in the same proportion. This sharing method easily leads to the situation that each power supply does not work in the best state. Summary of the invention

[0004] The embodiment of the present application provides a method, device and related equipment for controlling the output power of a power supply, which can improve the working efficiency of the power supply and thus reduce the loss of the power supply. The technical solution is as follows:

[0005] In a first aspect, a method for controlling power output of a power supply is provided. In the method, the operating power consumption of a powered device is obtained; based on the operating power consumption, a first target output power of a first power supply and a second target output power of a second power supply are determined, the first power supply and the second power supply are power supplies that provide power to the powered device, and the first target output power and the second target output power are different; the first power supply is controlled to supply power according to the first target output power, and the second power supply is controlled to supply power according to the second target output power.

[0006] The method provided in the embodiment of the present application can flexibly adjust the load distribution ratio between each power supply, so as to realize dynamic improvement of power supply efficiency without increasing any cost, thereby improving energy efficiency and maximizing power supply efficiency. In addition, the method provided in the embodiment of the present application can be implemented by a software module, requiring a small amount of code and having basically zero impact on power supply reliability.

[0007] Based on the method provided in the first aspect, in a possible implementation method, the implementation method of determining the first target output power of the first power supply and the second target output power of the second power supply according to the operating power consumption can be: obtaining a first reference ratio and a second reference ratio, either of the first reference ratio and the second reference ratio is used to indicate the operating power consumption of the powered device shared by the first power supply and the operating power consumption of the powered device shared by the second power supply; determining the total power loss under the first reference ratio and the total power loss under the second reference ratio: selecting a target reference ratio from the first reference ratio and the second reference ratio according to the total power loss under the first reference ratio and the total power loss under the second reference ratio; determining the first target output power of the first power supply and the second target output power of the second power supply according to the target reference ratio and the operating power consumption.

[0008] Using the total power loss as a standard for adjusting the power output power can reduce the loss of each power supply after the output power is adjusted, thereby improving the efficiency of each power supply. Therefore, the embodiment of the present application provides a method for flexibly adjusting the power output power of a power supply, and the method can also improve the efficiency of each power supply.

[0009] Based on the method provided in the first aspect, in a possible implementation method, the implementation method of determining the total power loss under the first reference ratio and the total power loss under the second reference ratio can be: according to any reference ratio of the first reference ratio and the second reference ratio and the operating power consumption of the powered device, determine the respective loads of the first power supply and the second power supply under the reference ratio; obtain the corresponding relationship between the load and efficiency of the first power supply and the corresponding relationship between the load and efficiency of the second power supply; determine the total power loss under the reference ratio according to the corresponding relationship between the load and efficiency of the first power supply and the corresponding relationship between the load and efficiency of the second power supply, as well as the respective loads of the first power supply and the second power supply under the reference ratio.

[0010] In the embodiment of the present application, the total power loss under any reference ratio can be quickly determined based on the pre-configured corresponding relationship between the load and efficiency of each power supply, thereby improving the efficiency of determining the power output power of the power supply.

[0011] Since the corresponding relationship between load and efficiency under different power supply parameters may be different, in the embodiment of the present application, the specific implementation method of determining the total power loss under any reference ratio may have different implementation processes in the following two scenarios.

[0012] Scenario 1:

[0013] Based on the method provided in the first aspect, in a possible implementation, the correspondence between the load and efficiency of any power supply includes the correspondence between the load and efficiency under different power supply parameters, the power supply parameters include the power supply frequency, and the total power loss under each reference ratio includes the total loss determined based on the correspondence between the load and efficiency under different power supply parameters. In this scenario, the implementation method of selecting the target reference ratio from the first reference ratio and the second reference ratio based on the total power loss under the first reference ratio and the total power loss under the second reference ratio can be: from the total loss determined based on the correspondence between the load and efficiency under different power supply parameters included in the total power loss, select the minimum total loss corresponding to the first reference ratio or the second reference ratio; obtain the minimum value of the minimum total loss corresponding to the first reference ratio or the second reference ratio, and determine the reference ratio corresponding to the minimum value as the target reference ratio.

[0014] Based on the method provided in the first aspect, in a possible implementation, in the method, power supply parameters of the first power supply and the power supply parameters of the second power supply used to determine the target reference ratio can also be obtained; the first power supply is controlled to operate according to the obtained power supply parameters of the first power supply, and the second power supply is controlled to operate according to the obtained power supply parameters of the second power supply.

[0015] Scenario 2:

[0016] Based on the method provided in the first aspect, in a possible implementation, the corresponding relationship between the load and the efficiency is the corresponding relationship between the load and the efficiency under the reference power supply parameters, and the reference power supply parameters include the reference power supply frequency. In this scenario, the above-mentioned target reference ratio is the optimal load sharing ratio only under the reference power supply parameters.

[0017] In scenario two, you can continue to obtain the correspondence between the load and efficiency of the first power supply under different power supply parameters, and the correspondence between the load and efficiency of the second power supply under different power supply parameters, and then determine the first power supply parameters and the second power supply parameters based on the correspondence between the load and efficiency of the first power supply under different power supply parameters, and the correspondence between the load and efficiency of the second power supply under different power supply parameters, and the target reference ratio, the first power supply parameters refer to the power supply parameters corresponding to the maximum efficiency of the first power supply under the target reference ratio, and the second power supply parameters refer to the power supply parameters corresponding to the maximum efficiency of the second power supply under the target reference ratio; control the first power supply to operate according to the first power supply parameters, and control the second power supply to operate according to the second power supply parameters.

[0018] In the above two scenarios, when adjusting the output power of the power supply, the power supply parameters of the power supply may be further adjusted to improve the working efficiency of the power supply and reduce the working loss of the power supply.

[0019] Based on the method provided in the first aspect, in a possible implementation method, determining the first target output power of the first power supply and the second target output power of the second power supply according to the operating power consumption can be: determining the operating power consumption jitter of the powered device within a preset time period; determining that the operating power consumption jitter meets the reference conditions, and then determining the first target output power of the first power supply and the second target output power of the second power supply according to the operating power consumption.

[0020] In the embodiment of the present application, the frequency of adjusting the output power of the power supply can be reduced through temporal and spatial de-jittering processing. In addition, the power consumption of the powered device in the actual service scenario is relatively stable, thereby avoiding unnecessary output power adjustment.

[0021] Based on the method provided in the first aspect, in a possible implementation, after controlling the first power supply to supply power according to the first target output power and controlling the second power supply to supply power according to the second target output power, in this method, the actual total loss during the process of the first power supply supplying power according to the first target output power and the second power supply supplying power according to the second target output power can also be obtained; if the actual total loss is greater than the reference total loss, the output power of the first power supply is adjusted to the first reference output power, and the output power of the second power supply is adjusted to the second reference output power. Wherein, the reference total loss refers to the actual total loss during the process of the first power supply working according to the first reference output power and the second power supply working according to the second reference output power.

[0022] After adjusting the output power of the first power supply and the output power of the second power supply by the method provided in the embodiment of the present application, the actual losses of the first power supply and the second power supply may be further monitored to avoid regulation errors.

[0023] Based on the method provided in the first aspect, in a possible implementation method, the implementation method of obtaining the operating power consumption of the powered device can be: displaying a control interface, the control interface including a load sharing adjustment control; and obtaining the operating power consumption of the powered device in response to a trigger operation on the load sharing adjustment control.

[0024] In the embodiment of the present application, the power output power can also be adjusted based on the user's operation, which improves the flexibility of the method provided in the embodiment of the present application.

[0025] Optionally, the powered device is a server, and the rated power of the first power supply is the same as the rated power of the second power supply. The method provided in the embodiment of the present application can be specifically applied in a scenario where two identical power supplies are used to power a server, thereby improving the application flexibility of the method provided in the embodiment of the present application.

[0026] In a second aspect, a device for controlling power output of a power supply is provided, the device having the function of implementing the method for controlling power output of a power supply in the first aspect. The device comprises at least one module, the at least one module being used to implement the method for controlling power output of a power supply provided in the first aspect.

[0027] In a third aspect, an electronic device is provided, the structure of which includes a processor and a memory, the memory is used to store program code, and the processor is used to execute the program code to implement any method as described in the first aspect above.

[0028] In a fourth aspect, a computer-readable storage medium is provided, wherein instructions are stored in the computer-readable storage medium.

[0029] In a fifth aspect, a computer program product comprising instructions is provided. When the instructions are executed on a computer, the computer executes the method for controlling the output power of a power supply as described in the first aspect.

[0036] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0037] Before explaining the embodiments of the present application in detail, the application scenarios of the embodiments of the present application are first explained.

[0038] As the performance of current servers is getting better and better, the power consumption of servers is also getting higher and higher. At this time, it is particularly important to improve the efficiency of multiple power supplies that provide power to the server. Currently, the various power supplies that provide power to the server use an equal-proportional load balancing mode to power the server, which seriously affects the power efficiency. Among them, the equal-proportional load balancing mode refers to controlling each power supply to power the server at the same output power.

[0039] The method for controlling the output power of a power supply provided in the embodiment of the present application is applied to the multiple power supplies for supplying power to the server, and aims to provide a control method capable of improving the efficiency of the power supply.

[0040] Figure 1 Schematic diagram of a power system architecture provided by an embodiment of the present application. Figure 1 As shown, the power supply system 100 includes a powered device 101, a first power supply 102, a second power supply 103, and a controller 104. The first power supply 102 and the second power supply 103 are respectively connected to the powered device 101 to supply power to the powered device 101. In addition, the first power supply 102 and the second power supply 103 are also respectively connected to the controller 104 to realize that the controller 104 controls the output power of the first power supply 102 and the second power supply 103 to supply power to the powered device 101.

[0041] The first power supply 102 and the second power supply 103 can be power supplies with the same specification parameters, or can be power supplies with different specification parameters. The embodiment of the present application does not limit this. Among them, the specification parameters include rated power, and can also include other operating parameters of the power supply, such as input voltage, output voltage, operating temperature range and other parameters.

[0042] The above-mentioned powered device 101 can be a server or other type of network device that requires multiple power supplies. Any device powered by at least two power supplies is within the protection scope of the powered device provided in the embodiment of the present application. The controller 104 can be a control device independent of the server, or a baseboard management controller (BMC) deployed on the server. The BMC can be implemented by a unit with processing functions such as a control chip or a system on a chip embedded in the server, and the embodiment of the present application does not specifically limit this.

[0043] It should be noted that Figure 1 Two power supplies are merely used as an example for illustration. There may be multiple power supplies for supplying power to the powered device 101 . The embodiment of the present application does not limit the number of power supplies configured for the powered device 101 .

[0044] The method for controlling the output power of a power supply provided in an embodiment of the present application is explained in detail below.

[0045] Figure 2 1 is a flow chart of a method for controlling the output power of a power supply provided in an embodiment of the present application. Figure 2 As shown, the method includes the following steps.

[0046] Step 201: The controller obtains the operating power consumption of the powered device.

[0047] The operating power consumption of the above-mentioned powered device may be the average operating power consumption of the powered device in a period of time before the current time and closest to the current time. For example, the operating power consumption of the powered device may be the average operating power consumption of the powered device in the last hour before the current time. Optionally, the operating power consumption of the above-mentioned powered device may also be the operating power consumption of the powered device at the current time.

[0048] In a possible implementation, the controller can determine the operating power consumption of the powered device based on the output power of each power supply for the powered device and the loss from the power output port to the power supply port of the powered device. Optionally, the operating power consumption of the powered device can also be determined by other means. For example, the network power consumption of the powered device can be determined by a power meter or power sensor installed at the power supply port of the powered device.

[0049] In addition, in the embodiment of the present application, the controller can periodically and directly execute the method for controlling the output power of the power supply provided in the embodiment of the present application. In this case, the controller can execute the following step 202 each time it obtains the operating power consumption of the powered device.

[0050] Optionally, after obtaining the operating power consumption of the powered device each time, the controller may also first determine the operating power consumption jitter of the powered device within a preset time period. If it is determined that the operating power consumption jitter meets the reference condition, the following step 202 is performed. Among them, the reference condition may include: the number of power consumption jitters of the powered device within a preset time period exceeds the reference number, and the historical duration is greater than the duration threshold. Among them, the number of power consumption jitters refers to the number of times the amplitude of the power consumption change that occurs within the preset time period exceeds the amplitude threshold. This can avoid adjusting the output power of the power supply in some unnecessary situations, so that the power supply works in a stable state.

[0051] For example, when the operating power consumption of the powered device changes significantly in a short period of time, there is no need to adjust the output power of each power supply. Alternatively, when the operating power consumption of the powered device changes dramatically over a long period of time, but the frequency of the dramatic changes is very low, there is no need to adjust the output power of each power supply in this scenario. It can be seen that in the embodiment of the present application, the frequency of adjusting the output power of the power supply can be reduced through de-jittering processing in time and space. In addition, the power consumption of the powered device in the actual business scenario is also relatively stable, thereby avoiding unnecessary output power adjustment.

[0052] In another possible implementation, the controller may also trigger an operation to adjust the power output power of the power supply based on a user operation. Specifically, the controller displays a control interface, and the control interface includes a load sharing adjustment control. In this scenario, in response to a trigger operation for the load sharing adjustment control, the operating power consumption of the powered device is obtained. The trigger operation for the load sharing adjustment control may be triggered by a user through a preset operation. The preset operation may be a click operation, a sliding operation, a voice operation, or the like.

[0053] In addition, in the scheme where the controller periodically and automatically triggers step 201, the user can also configure some parameters for adjusting the power output power in advance through the control interface. For example, the user can configure whether to enable the controller to adjust the power output power, or further configure the duration of the cycle for the controller to adjust the power output power. Optionally, it is also possible to configure whether the power parameters of each power supply are variable, and the power parameters may include specification parameters such as power frequency. The specific functions of the power parameters will be explained in detail in subsequent steps, so they will not be elaborated here.

[0054] Step 202: The controller determines a first target output power of a first power source and a second target output power of a second power source according to the operating power consumption, wherein the first power source and the second power source are power sources that provide power to the powered device, and the first target output power and the second target output power are different.

[0055] In the embodiment of the present application, the power sources for powering the powered device may be two or more. Step 202 and step 203 are described by taking two power sources as an example, and do not constitute a limitation on the embodiment of the present application. For ease of description, the two power sources are referred to as the first power source and the second power source. When there are multiple power sources for powering the powered device, the output power of the multiple power sources can also be determined with reference to step 202, and the embodiment of the present application does not limit this.

[0056] In order to solve the problem that the first power supply and the second power supply share the operating power consumption of the powered device in the same proportion in the related art, resulting in low power efficiency, in the embodiment of the present application, the controller can determine the first target output power of the first power supply and the second target output power of the second power supply according to the operating power consumption of the powered device, so that the first power supply works according to the first target output power and the second power supply works according to the second target output power. Compared with the related art that the first power supply and the second power supply can only share the load in a ratio of 50%:50%, the controller can flexibly adjust the target output power of the first power supply and the second power supply, without being restricted to the first power supply and the second power supply can only share the load in a ratio of 50%:50%, the purpose is to improve the working efficiency of the first power supply and the second power supply, and reduce the loss of the first power supply and the second power supply.

[0057] In a possible implementation, the implementation process of step 202 may be: obtaining a first reference ratio and a second reference ratio, either of which is used to indicate the operating power consumption of the powered device shared by the first power source and the operating power consumption of the powered device shared by the second power source. Determine the total power loss under the first reference ratio and the total power loss under the second reference ratio. Select a target reference ratio from the first reference ratio and the second reference ratio based on the total power loss under the first reference ratio and the total power loss under the second reference ratio. Determine a first target output power of the first power source and a second target output power of the second power source according to the target reference ratio and the operating power consumption.

[0058] Using the total power loss as a standard for adjusting the power output power can reduce the loss of each power supply after the output power is adjusted, thereby improving the efficiency of each power supply. Therefore, the embodiment of the present application provides a method for flexibly adjusting the power output power of a power supply, and the method can also improve the efficiency of each power supply.

[0059] The first reference ratio and the second reference ratio may be any two reference ratios selected in advance according to a certain step length. These multiple reference ratios may be multiple ratios selected according to a certain step length from 100%:0 to 0:100%. The step length may be flexibly configured. For example, if the step length is 5%, the multiple reference ratios are 18 reference ratios of 95%:5%, 90%:10%, 85%:15%, 80%:20%, ..., 10%:90%, 5%:95% in sequence. Among them, the numerical value before the colon of each reference ratio indicates the ratio between the operating power consumption of the powered device that the first power source needs to share and the total operating power consumption of the powered device, and the numerical value after the colon indicates the ratio between the operating power consumption of the powered device that the second power source needs to share and the total operating power consumption of the powered device. Therefore, any of the above reference ratios is used to indicate the operating power consumption of the powered device that the first power source needs to share and the operating power consumption of the powered device that the second power source needs to share.

[0060] The above-mentioned target reference ratio can be a reference ratio with the smallest total power loss. Optionally, the above-mentioned target reference ratio can also be a reference ratio among the reference ratios in which the total power loss is lower than the loss threshold. At this time, the controller can randomly select a reference ratio from the reference ratios in which the total power loss is lower than the loss threshold. It is also possible to select a reference ratio that is closest to 50%:50% from the reference ratios in which the total power loss is lower than the loss threshold. The technical effect of this is that it can ensure as much as possible that each power supply shares the load in a load balancing manner, so as to avoid excessive gap between the loads shared by the two power supplies, resulting in excessive depreciation of one of the two power supplies.

[0061] In addition, in an embodiment of the present application, the above-mentioned determination of the total power loss under a certain reference ratio can be obtained based on the total power loss of the first power supply and the second power supply when working at various reference ratios, which is pre-stated by the controller. Optionally, the above-mentioned determination of the total power loss under a certain reference ratio can be determined by the corresponding relationship between the load and efficiency of the first power supply pre-configured in the controller, and the corresponding relationship between the load and efficiency of the second power supply pre-configured in the controller. At this time, the determined total power loss can also be referred to as the theoretical total power loss. The following content is used to explain in detail the specific implementation method of determining the total power loss based on the corresponding relationship between the pre-configured load and efficiency.

[0062] In a possible implementation, the implementation process of determining the total power loss at each reference ratio of the first reference ratio and the second reference ratio may be as follows: for any reference ratio of the first reference ratio and the second reference ratio, determine the respective loads of the first power supply and the second power supply at the reference ratio according to the reference ratio and the operating power consumption of the powered device, obtain the corresponding relationship between the load and efficiency of the first power supply, and the corresponding relationship between the load and efficiency of the second power supply, and determine the total power loss at the reference ratio according to the respective loads of the first power supply and the second power supply at the reference ratio, the corresponding relationship between the load and efficiency of the first power supply, and the corresponding relationship between the load and efficiency of the second power supply.

[0063] The above-mentioned method of determining the respective loads of the first power supply and the second power supply at the reference ratio based on the reference ratio and the operating power consumption of the powered device can be: determining the power consumption that the first power supply and the second power supply need to share at the reference ratio based on the reference ratio and the operating power consumption of the powered device, and determining the respective loads of the first power supply and the second power supply at the reference ratio based on the power consumption that the first power supply and the second power supply need to share.

[0064] The above-mentioned implementation method of determining the total power loss under the reference ratio according to the respective loads of the first power supply and the second power supply under the reference ratio, the corresponding relationship between the load and efficiency of the first power supply, and the corresponding relationship between the load and efficiency of the second power supply can be: determining the efficiency of the first power supply according to the load of the first power supply and the corresponding relationship between the load and efficiency of the first power supply, determining the efficiency of the second power supply according to the load of the second power supply and the corresponding relationship between the load and efficiency of the second power supply, and determining the total power loss under the reference ratio according to the respective efficiencies of the first power supply and the second power supply, and the power consumption that the first power supply and the second power supply need to share.

[0065] Specifically, the above implementation can be represented by the following formula:

[0066]

[0067] Wherein, X represents the proportion of the first power source in any reference proportion. P_load represents the operating power consumption of the powered device. η1 represents the efficiency of the first power source when the output power of the first power source is P_load*X. η2 represents the efficiency of the second power source when the output power of the second power source is P_load*(1-X).

[0068] In addition, the corresponding relationship between the load and efficiency of any of the above power supplies is used to indicate the change in the efficiency of the power supply as the load of the power supply changes. The load of the power supply can be the output power of the power supply or the ratio between the output power of the power supply and the rated power of the power supply. The efficiency of the power supply refers to the ratio between the output power of the power supply and the input power of the power supply.

[0069] Figure 3 Schematic diagram of the corresponding relationship between the load and efficiency of a power supply provided in an embodiment of the present application. Figure 3 As shown, the corresponding relationship between the load and efficiency of the power supply can be represented by a curve. Figure 3 The horizontal axis in is used to indicate the load of the power supply, which is characterized by the ratio between the output power of the power supply and the rated power of the power supply. Figure 3 The vertical axis shown is used to indicate the efficiency of the power supply. The higher the efficiency of the power supply, the smaller the loss of the power supply. The lower the efficiency of the power supply, the greater the loss of the power supply.

[0070] In addition, it should be noted that Figure 3 The corresponding relationship between the load and efficiency of the power supply shown can be the corresponding relationship between the load and efficiency of the power supply under specified power supply parameters. The power supply parameters include parameters of power supply specifications such as power supply frequency. When the power supply parameters are different, Figure 3 The efficiency shown for the same load may vary. For example, Figure 3 The curve shown in FIG. 1 shows the corresponding relationship between the load and the efficiency when the frequency of the power supply is at the first frequency. At this time, when the load is 10%, the efficiency of the power supply is 90.2%. When the frequency of the power supply is adjusted to the second frequency, the corresponding efficiency when the load is 10% may be 85%. The first frequency and the second frequency are different power supply frequencies.

[0071] Therefore, the specific implementation method of determining the total power loss at each reference ratio in multiple reference ratios based on the operating power consumption and the corresponding relationship between the load and efficiency of the first power supply and the second power supply can have different implementation processes in the following two scenarios.

[0072] Scenario 1: The corresponding relationship between the load and efficiency of each of the first power supply and the second power supply includes the corresponding relationship between the load and efficiency under different power supply parameters. The power supply parameters include power supply frequency, etc. In this scenario, the total power loss under each reference ratio determined above includes the total loss determined based on the corresponding relationship between the load and efficiency under different power supply parameters.

[0073] At this time, the above-mentioned method of selecting the target reference ratio from the first reference ratio and the second reference ratio according to the total power loss under each reference ratio can be as follows: from the theoretical total losses determined based on the correspondence between the load and the efficiency under different power parameters, which are included in the total power loss under any reference ratio, the minimum theoretical total loss corresponding to the reference ratio is selected, and the reference ratio corresponding to the minimum value of the minimum theoretical total losses corresponding to each reference ratio is determined as the target reference ratio.

[0074] For example, for a reference ratio of 45%:55%, it is assumed that the theoretical total loss at different power supply frequencies determined under the reference ratio is as shown in the following Table 1. According to the content shown in Table 1, the minimum theoretical total loss corresponding to the reference ratio is 48W.

[0075] Table 1

[0076]

[0077] It should be noted that the target reference ratio at this time involves the selection of power supply parameters. Therefore, the controller can also obtain the power supply parameters of the first power supply and the power supply parameters of the second power supply used when determining the target reference ratio. Among them, the power supply parameters of the first power supply are the power supply parameters of the first power supply and the power supply parameters of the second power supply used when determining the minimum theoretical total loss mentioned above, and then the first power supply is controlled to work according to the obtained power supply parameters of the first power supply, and the second power supply is controlled to work according to the obtained power supply parameters of the second power supply. In this way, the total power loss of the first power supply and the second power supply can reach the minimum value of the minimum theoretical total loss determined above.

[0078] Scenario 2: The corresponding relationship between the load and efficiency of each of the first power supply and the second power supply is the corresponding relationship between the load and efficiency under the reference power supply parameters. The reference power supply parameters include the reference power supply frequency. At this time, the above-mentioned target reference ratio is the optimal load sharing ratio only under the reference power supply parameters. The reference power supply parameters can be the power supply parameters used by the first power supply and the second power supply before adjusting the output power.

[0079] In this scenario, the controller can further adjust the power supply parameters of the first power supply and the second power supply to reduce the total power supply loss when the first power supply and the second power supply output power at the target reference ratio. Therefore, in a possible implementation, the controller can also obtain the corresponding relationship between the load and efficiency of the first power supply under different power supply parameters, and the corresponding relationship between the load and efficiency of the second power supply under different power supply parameters; according to the corresponding relationship between the load and efficiency of the first power supply under different power supply parameters, and the corresponding relationship between the load and efficiency of the second power supply under different power supply parameters, and the target reference ratio, determine the first power supply parameter and the second power supply parameter, the first power supply parameter refers to the power supply parameter corresponding to the maximum efficiency of the first power supply under the target reference ratio, and the second power supply parameter refers to the power supply parameter corresponding to the maximum efficiency of the second power supply under the target reference ratio.

[0080] The above-mentioned implementation method for determining the first power supply parameter and the second power supply parameter can be: the controller determines the efficiency range of the load of the first power supply under different power supply parameters at the target reference ratio according to the corresponding relationship between the load and efficiency of the first power supply under different power supply parameters, and determines the efficiency range of the load of the second power supply under different power supply parameters at the target reference ratio according to the corresponding relationship between the load and efficiency of the second power supply under different power supply parameters. Then, the power supply parameter corresponding to the maximum efficiency is selected from the efficiency range of the load of the first power supply under different power supply parameters to obtain the first power supply parameter, and the power supply parameter corresponding to the maximum efficiency is selected from the efficiency range of the load of the second power supply under different power supply parameters to obtain the second power supply parameter.

[0081] The efficiency range of the load of the first power supply under the target reference ratio under different power supply parameters can be directly obtained from the corresponding relationship between the load and the efficiency under different power supply parameters. The efficiency range of the load of the second power supply under the target reference ratio under different power supply parameters can also be determined in this way. No further details are given here.

[0082] In addition, in the above-mentioned scenario 1 and scenario 2, the power supply parameters of the first power supply and the second power supply are allowed to be adjusted. Optionally, if the power supply parameters of the first power supply and the second power supply are not adjustable, that is, the power supply parameters of the first power supply and the second power supply are fixed, then an optimal reference ratio can be directly determined based on the corresponding relationship between the load and efficiency under the fixed power supply parameters. Then, the output power of the first power supply and the second power supply is adjusted according to the optimal reference ratio.

[0083] Whether the power supply parameters of the power supply can be adjusted can be configured by each power supply at the factory, or can be configured by an administrator based on the aforementioned control interface, which is not limited in the present embodiment of the application.

[0084] Step 203: The controller controls the first power supply to supply power according to the first target output power, and controls the second power supply to supply power according to the second target output power.

[0085] After determining the first target output power and the second target output power according to the target reference ratio, the controller can control the first power supply to supply power according to the first target output power and control the second power supply to supply power according to the second target output power, thereby reducing the total power loss of the first power supply and the second power supply, and then improving the efficiency of the first power supply and the second power supply. It can be seen that, through the method provided by the embodiment of the present application, the controller can flexibly adjust the load distribution ratio between each power supply, and can achieve dynamic improvement of power supply efficiency without increasing any cost, thereby improving energy efficiency, and then maximizing power supply efficiency. In addition, the method provided by the embodiment of the present application can be implemented by a software module, with a small amount of code required, and basically zero impact on power supply reliability.

[0086] The following is a specific example to further illustrate the technical effect of the method provided in the embodiment of the present application:

[0087] Assume that the above-mentioned powered device is a server, the server operating power consumption is 600W, the rated power of the first power supply and the second power supply are both 2000W, and the first power supply and the second power supply are power supplies of the same specification. When the first power supply and the second power supply share the load at a ratio of 50%:50%, the total loss of the two power supplies is shown in the following Table 2:

[0088] Table 2

[0089]

[0090] The load sharing ratio between the first power supply and the second power supply is determined to be 5:1 by the method provided in the embodiment of the present application. At this time, the total loss of the first power supply and the second power supply is as shown in the following Table 3:

[0091] Table 3

[0092]

[0093] From the above comparison, we can conclude that the benefit of this solution is 48.78-44.93=3.85 (W). If the server operation time is 5 years, the electricity fee is 1 yuan / kWh, and a data center includes 10,000 servers, and the power usage effectiveness (PUE) of the data center is evaluated as 2, then the total electricity cost saved by the data center is: 3.85*24*365*5*10000*2 / 3600=940,000 yuan, and this benefit does not require any cost increase. Among them, PUE is the ratio of all energy consumed by the data center to the energy consumed by each powered device included in the data center.

[0094] In addition, after adjusting the output power of the first power supply and the output power of the second power supply by the method provided in the embodiment of the present application, the actual losses of the first power supply and the second power supply can be further monitored to avoid the occurrence of regulation errors. Specifically, after the controller controls the first power supply to supply power according to the first target output power and controls the second power supply to supply power according to the second target output power, the actual total loss in the process of the first power supply supplying power according to the first target output power and the second power supply supplying power according to the second target output power is obtained. If the actual total loss is greater than the reference total loss, the output power of the first power supply is adjusted to the first reference output power, and the output power of the second power supply is adjusted to the second reference output power.

[0095] The reference total loss refers to the actual total loss during the process in which the first power supply operates at the first reference output power and the second power supply operates at the second reference output power. The first reference output power and the second reference output power can be the respective output powers of the first power supply and the second power supply when the load is shared in a ratio of 50%:50%. Optionally, the first reference output power and the second reference output power can also be the respective output powers of the first power supply and the second power supply before the controller determines the first target output power and the second target output power.

[0096] It should be noted that Figure 2 The embodiment shown is explained based on the fact that the power supply source of the powered device is two. Optionally, when the power supply source of the powered device is more than three power sources, the above Figure 2 The embodiment shown adjusts the output power of each power supply. The principle of adjustment is to first determine a load sharing ratio with the smallest total power loss in theory according to the operating power consumption of the powered device, and then adjust the output power of each power supply according to the determined load sharing ratio. This embodiment of the present application does not provide a detailed description of this.
