具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，图1为本申请实施例提供的一种PSU供电方法的流程图。
本申请实施例提供的一种PSU供电方法，应用于IT设备，可以包括以下步骤：
步骤S101：获取IT设备的最大功率值。
实际应用中，IT设备可以先获取自身的最大功率值，具体的，可以通过功率指令获取自身的最大功率值，在此过程中，还可以获取自身各个部件的最大功率值，在将各个部件的最大功率值相加，得到IT设备的最大功率值；此外，还可以通过IT设备的设备信息获取IT设备的最大功率值。
步骤S102：获取IT设备中每个PSU的最大负载功率值。
实际应用中，在获取IT设备的最大功率值之后，还需获取IT设备中每个PSU的最大负载功率值，具体的，可以通过PSU的设备信息获取PSU自身的最大负载功率值。
步骤S103：在最大负载功率值中，判断是否存在大于等于最大功率值的目标最大负载功率值；若存在目标最大负载功率值，则执行步骤S104。
步骤S104：在目标最大负载功率值对应的目标PSU中，选择一个目标PSU为IT设备供电。
实际应用中，在获取IT设备的最大功率值和每个PSU的最大负载功率值之后，便可以在最大负载功率值中，判断是否存在大于等于最大功率值的目标最大负载功率值，若是，则在目标最大负载功率值对应的目标PSU中，选择一个目标PSU为IT设备供电。由于只是选择一个目标PSU为IT设备供电，所以可以使得该目标PSU的电能转换效率较高，因为申请人发现，PSU的电能转换效率与PSU自身负载有关，具体关系可以参阅表1；由表1可知，PSU的负载率在50％时，PSU的电能转换效率最高，负载率低于或者高于50％时，PSU的电能转换效率均降低，并且在PSU的负载率高于50％时，PSU的电能转换效率较高，而现有技术中，采用PSU1+1冗余供电的话，假设两个PSU的规格完全一致，均分后，每个PSU的负载率均小于50％，此时，两个PSU的电能转换率均较低，所以，为了提高PSU的电能转换率，需通过一个PSU为IT设备供电。

本申请提供的一种PSU供电方法，应用于IT设备，获取IT设备的最大功率值；获取IT设备中每个PSU的最大负载功率值；在最大负载功率值中，判断是否存在大于等于最大功率值的目标最大负载功率值；若存在目标最大负载功率值，则在目标最大负载功率值对应的目标PSU中，选择一个目标PSU为IT设备供电。本申请提供的一种PSU供电方法，IT设备中存在大于等于最大功率值的目标最大负载功率值时，在目标最大负载功率值对应的目标PSU中，选择一个目标PSU为IT设备供电，也即通过一个PSU为IT设备供电，这样可以使得单个PSU的电能转换效率较高，而现有技术中通过两个PSU为IT设备供电的技术相比，降低了PSU的电能浪费。
本申请提供的一种PSU供电方法，应用于IT设备，如果一直用一个PSU 为IT设备供电的话，会使得IT设备的其他PSU一直处于闲置状态，这会在一定程度上影响其他PSU的供电性能，并且会对一直供电的PSU产生性能损耗，为了避免此种情况，IT设备在目标最大负载功率值对应的目标PSU中，选择一个目标PSU为IT设备供电之后，还可以判断当前时刻是否属于预设时刻，若是，则另选择一个目标PSU代替已选择的目标PSU为IT设备供电。
也即本申请中，可以通过预设时长后，便更换单个PSU为IT设备供电，来降低一直为IT设备供电的PSU的性能损耗，并且解除其他PSU的闲置状态，在一定程度上保证其他PSU的性能。
本申请提供的一种PSU供电方法，应用于IT设备，由于PSU的电能转换效率与PSU的负载率有关，而PSU的电能转换效率决定了PSU的性能损耗，所以为了控制PSU的性能损耗，可以为PSU设置相应的电能转换率值，保证PSU可以尽可能的运行在设定的电能转换率值之上，因此，IT设备在目标最大负载功率值对应的目标PSU中，选择一个目标PSU为IT设备供电时，可以选择一个目标最大负载功率值作为当前负载功率值；获取IT设备的运行功耗值，计算运行功耗值与当前负载功率值间的比例值，判断比例值是否小于预设比例值；若比例值小于预设比例值，则选择当前负载功率值对应的目标PSU为IT设备供电；其中，预设比例值为目标PSU的电能转换效率大于等于预设值时，目标PSU的负载比例值。
本申请提供的一种PSU供电方法，应用于IT设备，判断比例值是否小于预设比例值之后，若比例值大于等于预设比例值，则可以设置IT设备的所有PSU为IT设备供电。
本申请提供的一种PSU供电方法，应用于IT设备，为了准确把握PSU的电能转换率，可以应用PSU的负载比例值与电能转换效率间的对应关系来准确确定预设比例值，则IT设备判断比例值是否小于预设比例值之前，还可以获取目标PSU的负载比例值与电能转换效率间的对应关系；获取设定的目标电能转换效率；基于对应关系和目标电能转换效率，确定预设比 例值。
假设外界要求PSU的电能转换率在93％以上，而PSU的电能转换率在93％以上时，PSU的负载率需在90％以下，因此可以将预设比例值设置为90％，这样，当IT设备的运行功耗值与当前负载功率值的比值小于90％时，便可以用当前负载功率值对应的目标PSU为IT设备供电，而当IT设备的运行功耗值与当前负载功率值的比值大于90％时，便可以设置IT设备的所有PSU为IT设备供电，此时，功耗均摊后，两个PSU的负载率在45％以上，离PSU的最佳负载率较近，与单个PSU供电方法相比，可以实现外界对PSU的电能转换率设定要求。此外，在需要严格分析的情况中，可以确定出PSU达到93％的电能转换效率时的最小负载率与最大负载率，相应的，判断比例值是否在最小负载率与最大负载率之间，若是，则在选择当前负载功率值对应的目标PSU为IT设备供电。
本申请提供的一种PSU供电方法，应用于IT设备，由于预设比例值的设定不仅决定了PSU的电能转换率，还决定了PSU的安全性能，比如预设比例值在95％以上时，可能因IT设备的功耗波动对PSU的安全产生影响，为了避免预设比例值影响PSU的安全，IT设备基于对应关系和目标电能转换效率，确定预设比例值时，可以获取PSU安全性能条件；基于对应关系、PSU安全性能条件、目标电能转换效率，确定预设比例值。
本申请提供的一种PSU供电方法，应用于IT设备，在最大负载功率值中，判断是否存在大于等于最大功率值的目标最大负载功率值之后，若不存在目标最大负载功率值，则在IT设备的所有PSU中，选择出功率总值大于等于最大功率值的PSU作为供电PSU。
实际应用中，在选择出功率总值大于等于最大功率值的PSU作为供电PSU时，为了满足IT设备的运行功耗，又可以使得PSU的损耗较低，可以选择出功率总值与预设比例值的乘值大于等于最大功率值的PSU作为供电PSU。预设比例值可以为目标PSU的电能转换效率大于等于预设值时，目标PSU的负载比例值，为了便于理解，假设IT设备一共有四个相同的PSU， IT设备的最大功率值大于单个PSU的最大负载功率值，小于两个PSU的功率总值的90％，则可以将该两个PSU作为供电PSU。
实际应用中，在选择出功率总值大于等于最大功率值的PSU作为供电PSU时，由于供电PSU的总功率值与最大功率值接近时，单个PSU的损耗最低，所以可以按照供电PSU的数量值尽可能少的原则，选择出功率总值大于等于最大功率值的PSU作为供电PSU。依旧假设IT设备一共有四个相同的PSU，假设IT设备的最大功率值等于两个PSU的功率总值，则采用两个PSU供电的话，单个PSU的负载率在50％左右，单个PSU的电能转换效率在95％左右，而采用三个PSU供电的话，单个PSU的负载率在33％左右，单个PSU的电能转换效率小于95％，所以，为了保证单个PSU的损耗最低，可以按照供电PSU的数量值尽可能少的原则，选择出功率总值大于等于最大功率值的PSU作为供电PSU。
本申请提供的一种PSU供电方法，应用于IT设备，在选择出功率总值大于等于最大功率值的PSU作为供电PSU之后，还可以判断IT设备的所有PSU中是否存在除供电PSU之外的剩余PSU；若存在，则用剩余PSU中的PSU替换供电PSU中的PSU。
实际应用中，为了保证IT设备可以持续工作，在用剩余PSU中的PSU替换供电PSU中的PSU时，可以在供电PSU中确定出待替换的第一PSU；在剩余PSU中确定出替换第一PSU的第二PSU；控制PSU为IT设备供电；控制第一PSU结束为IT设备供电。应当指出，第一PSU与第二PSU的数值相等，且该数值的最大值取决于供电PSU与剩余PSU的最小数量，假设供电PSU中有三个PSU，剩余PSU中有两个PSU，则第一PSU与第二PSU的数量均小于等于二。
