[0037] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The embodiments of the present application provide an embodiment of the AC / DC switching control method of a CRPS power supply. It should be noted that although the logical order is shown in the flow chart, under certain data, the steps shown or described can be completed in an order different from that here.

[0039] Before introducing the AC / DC switching control method of the CRPS power supply of the embodiment of the present application, the application scenario of the AC / DC switching control method of the CRPS power supply is first explained. The AC / DC switching control method of the CRPS power supply of the present application can be applied to smart terminals such as smart phones, tablets and computers, and can also be applied to servers. The present application does not make any special limitations here, as long as it can carry and implement the AC / DC switching control method of the CRPS power supply of the present application.

[0040] The following description will be given by applying the AC / DC switching control method of the CRPS power supply to the server side. However, it should be understood that the AC / DC switching control method of the CRPS power supply is not limited to being applied only to the server side.

[0041] Combine the following Figures 1 to 3 The present invention describes an AC / DC switching control method, device and electronic device of a CRPS power supply.

[0042] According to the embodiment of the first aspect of the present application, Figure 1 As shown, the CRPS power supply includes a plurality of power modules, and the power modules are used to supply power to the server. The AC / DC switching control method of the CRPS power supply includes:

[0043] Step 101: Obtaining power requirements of different servers;

[0044] Step 102: based on the power requirements of different servers, determine different servers as AC servers and DC servers;

[0045] Step 103: Based on the real-time power requirements of the AC server and the DC server, control a portion of the power modules to supply power to the AC server, and control the AC-DC conversion module to convert the output of another portion of the power modules into DC power to supply power to the DC server.

[0046] According to the embodiment of the present application, when the types of voltages required by different servers are different, some servers require AC power and some servers require DC power, different servers can be divided into AC servers that require AC power and DC servers that require DC power according to the power requirements of different servers. Then, the power supply power required by the AC server and the power supply power required by the DC server are obtained respectively, and a part of the power modules are determined to be used to power the AC server according to the power supply power required by the AC server, and then a part of the power modules are directly controlled to be electrically connected with the AC server to power the AC server, ensuring that a part of the power modules can meet the power demand of the AC server, and another part of the power modules are determined to be used to power the DC server according to the power supply power required by the DC server. At this time, another part of the power modules are controlled to be electrically connected with the AC-DC conversion module, so that the AC-DC conversion module can convert the AC power output by the power module into DC power and then power the DC server, ensuring that another part of the power modules can meet the power demand of the DC server. Then, by dividing multiple power modules, the output of a part of the power modules is converted into DC power to realize powering the DC server and the AC server at the same time, different power requirements can be met, and the intelligence of the CRPS power supply is improved.

[0047] In one embodiment of the present application, the input end of the AC / DC conversion module is suitable for being electrically connected to the power module, and the output end of the AC / DC conversion module is suitable for being electrically connected to the DC server, and the step of controlling a part of the power modules to supply power to the AC server and controlling another part of the power modules to supply power to the DC server includes:

[0048] Based on the first real-time required power of the AC server, control N first power modules to supply power to the AC server, wherein the sum of the maximum output powers of N-1 first power modules is greater than the first real-time required power;

[0049] Based on the second real-time required power of the DC server, M second power supply modules are controlled to be electrically connected to the input end of the AC-DC conversion module, wherein the sum of the maximum output powers of M-1 second power supply modules is greater than the second real-time required power.

[0050] It can be understood that the sum of the maximum output powers of N-1 of the first power modules is greater than the first real-time required power, thereby realizing a redundant design of the first power module for powering the AC server. When one of the first power modules fails, the power demand of the AC server can still be met.

[0051] It can be understood that the sum of the maximum output powers of M-1 second power supply modules is greater than the second real-time required power, thereby realizing a redundant design of the second power supply modules for powering the DC server. When one of the second power supply modules fails, the power demand of the DC server can still be met.

[0052] In one embodiment of the present application, after the step of controlling a part of the power modules to supply power to the AC server and controlling another part of the power modules to supply power to the DC server, the method further includes:

[0053] Determining a predicted required power of the AC server based on the work task of the AC server;

[0054] Based on the predicted required power of the AC server, the number of the power modules supplying power to the AC server is controlled and adjusted.

[0055] It is understandable that, according to the work tasks of the AC server, the work status of the AC server in a certain subsequent period of time can be determined, and the power required by the AC server in a certain subsequent period of time can also be determined, that is, the predicted required power. Then, according to the predicted required power, the number of power modules supplying power to the AC server is increased or decreased, so that the power modules supplying power to the AC server have a certain redundancy, and the redundancy is not too large to avoid waste of power modules.

[0056] Specifically, when the predicted power requirement of the AC server is greater than the real-time power requirement of the AC server, the number of power modules that need to be added is determined based on the difference between the predicted power requirement and the real-time power requirement, to ensure that the multiple power modules supplying power to the AC server can meet the power demand of the AC server for a certain period of time in the future, thereby avoiding power supply fluctuations caused by temporarily increasing or decreasing the number of power modules.

[0057] In one embodiment of the present application, after the step of controlling a part of the power modules to supply power to the AC server and controlling another part of the power modules to supply power to the DC server, the method further includes:

[0058] Determining a predicted required power of the DC server based on the work task of the DC server;

[0059] Based on the predicted required power of the DC server, the number of the power modules supplying power to the DC server is controlled and adjusted.

[0060] It is understandable that, according to the work tasks of the AC server, the work status of the DC server in a certain subsequent period of time can be determined, and the power required by the DC server in a certain subsequent period of time can also be determined, that is, the predicted required power. Then, according to the predicted required power, the number of power modules supplying power to the DC server is increased or decreased, so that the power modules supplying power to the DC server have a certain redundancy, and the redundancy is not too large to avoid waste of power modules.

[0061] Specifically, when the predicted required power of the DC server is greater than the real-time required power of the DC server, the number of power modules that need to be added is determined based on the difference between the predicted required power and the real-time required power, to ensure that the multiple power modules supplying power to the DC server can meet the power demand of the DC server for a certain period of time in the future, thereby avoiding power supply fluctuations caused by temporary increases or decreases in the number of power modules.

[0062] In one embodiment of the present application, the control method further includes:

[0063] Determining the real-time required power based on the number of the servers and the working modes of the servers;

[0064] Based on the maximum output power of the power module and the real-time required power, the operations of the plurality of power modules are controlled.

[0065] According to the AC / DC switching control method of the CRPS power supply of the embodiment of the present application, the number of servers that need electricity and the working mode of each server are obtained. Because the power required by different servers in different working modes is different, the real-time required power of all servers can be determined according to the number of servers and the working mode of the servers. When powering the server, generally only part of the power modules of the CRPS power supply are used, and some of the power modules of the CRPS power supply are not used to power the server; while the present application determines the number of required power modules according to the maximum output power and real-time required power of the power module, that is, determines how many power modules are used to meet the power demand of the server, and then controls the corresponding number of power modules to power the server, and the remaining power modules temporarily stop working. In other words, the present application realizes the accurate determination of the number of required power modules based on the real-time required power of the server, and then can accurately control the operation of multiple power modules, thereby improving the intelligence of the CRPS power supply.

[0066] In one embodiment of the present application, at least some of the power modules have different maximum output powers, and the step of controlling the operation of the plurality of power modules includes:

[0067] Determining predicted required power of different servers based on different work tasks of the servers;

[0068] Based on the predicted required power of different servers, different power modules are controlled to supply power to different servers respectively.

[0069] It is understandable that, according to the work tasks of the server, the work status of the server in a certain subsequent period of time can be determined, and the power required by the server in a certain subsequent period of time can also be determined, that is, the predicted required power. Then, according to the predicted required power of the server, the corresponding power module is controlled to supply power to the corresponding server, so as to ensure that the corresponding power module can ensure the power demand of the corresponding server in a certain subsequent period of time, without adding or reducing the power module in the middle, thereby ensuring the stability of power supply.

[0070] In one embodiment of the present application, the step of controlling different power modules to respectively supply power to different servers includes:

[0071] Based on the real-time power required by the target server and the predicted power required, the target power module is controlled to supply power to the target server, wherein the real-time power required by the target server and the predicted power required are both less than the maximum output power of the target power module.

[0072] It can be understood that the target power module is determined based on the real-time power required and predicted power required by the target server. The maximum output power of the target power module will be greater than the real-time power required by the target server to ensure that the target power module can meet the current power demand of the target server. The maximum output power of the target power module will be greater than the predicted power required by the target server, ensuring that the target power module can meet the power demand of the target server for a certain period of time in the future and ensuring that the server can operate stably.

[0073] In one embodiment of the present application, the step of controlling different power modules to respectively supply power to different servers includes:

[0074] In one embodiment of the present application, the control method further includes:

[0075] Obtain the real-time status parameters of each power module;

[0076] Based on the real-time status parameters of each power module, determining whether the real-time status parameters of one of the power modules are lower than a threshold;

[0077] If the real-time status parameter of one of the power modules is lower than a threshold, control is performed to replace one of the power modules.

[0078] It can be understood that by detecting the real-time status parameters of the power module, when the real-time status parameters are lower than the threshold, it means that the power module is already in an abnormal state. Therefore, the power module is directly replaced to ensure the stability of the power supply and avoid power supply fluctuations caused by replacing the power module after it fails and stops working.

[0079] Specifically, the real-time status parameter may be one or more comprehensively processed parameters of the output voltage, output current, and real-time temperature of the power module.

[0080] In one embodiment of the present application, the power module includes a charge-discharge battery, and the control method further includes:

[0081] Obtaining the internal expansion force of the charging and discharging battery of the target power module;

[0082] Determining that the internal expansion force is greater than a preset value;

[0083] Control the replacement target power module.

[0084] It can be understood that by detecting the internal expansion force of the charging and discharging battery, when the internal expansion force is greater than the preset value, it means that the charging and discharging battery is about to be damaged, so the power module is directly replaced to ensure the stability of the power supply and avoid power supply fluctuations caused by replacing the power module after it fails and stops working.

[0085] In one embodiment of the present application, the power module is formed with a coolant pipeline, the coolant pipeline is connected to a coolant output pump, and the coolant output pump is used to transport coolant to the coolant output pipeline, and the control method further includes:

[0086] Get the output power of different power modules;

[0087] Based on the output power of different power modules, the coolant delivery pump is controlled to adjust the flow rate of the coolant in the coolant pipelines of the different power modules.

[0088] It is understandable that when the output power of the power module is high, the flow rate of the coolant in the coolant pipeline of the power module is accelerated to better dissipate the heat of the power module. When the output power of the power module is low, the flow rate of the coolant in the coolant pipeline of the power module is reduced so that the coolant delivery pump can deliver more coolant to other power modules with higher output power, thereby achieving reasonable use of the coolant.

[0089] In one embodiment of the present application, the control method further includes:

[0090] A power module that is not in a power supply state is determined as an idle power module;

[0091] Control the idle power modules to supply power to the resistors respectively;

[0092] Determine that the power module in power supply state fails;

[0093] The idle power modules are controlled to stop supplying power to the resistor and switch to supplying power to the server corresponding to the failed power module.

[0094] It can be understood that the control display power module is in working state in advance. When the power module in the power supply state fails, the power module can directly switch to power the corresponding server to avoid temporary startup and prevent power supply fluctuations caused by voltage fluctuations when the idle power module is started.

[0095] According to the embodiment of the second aspect of the present application, the AC / DC switching control device of the CRPS power supply and the AC / DC switching control method of the CRPS power supply correspond to each other.

[0101] The third control module is used to control the M second power supply modules to be electrically connected to the input end of the AC-DC conversion module based on the second real-time required power of the DC server, wherein the sum of the maximum output powers of M-1 second power supply modules is greater than the second real-time required power.
