10. A power support unit of a server, comprising: a plurality of voltage converters and a processing chip, wherein
the plurality of voltage converters are deployed in parallel; the processing chip is connected to each voltage converter; the power support unit is connected between a power supply of a server to be powered and the server;
the processing chip is configured for: obtaining a target power supply power of the server; selecting one or more target voltage converters matched with the target power supply power from the plurality of voltage converters; and controlling the one or more target voltage converters to supply power to the server;
each target voltage converter is configured for converting a power supply voltage of the power supply into a power supply voltage of the server;
the selecting one or more target voltage converters matched with the target power supply power from the plurality of voltage converters comprises:
obtaining a full-load power that is allowed to be output by each voltage converter; and
selecting the one or more target voltage converters allowed to output the target power supply power from the plurality of voltage converters according to the full-load powers, wherein a total power that is allowed to be output by the one or more target voltage converters is greater than or equal to the target power supply power;
the selecting the one or more target voltage converters allowed to output the target power supply power from the plurality of voltage converters according to the full-load powers comprises:
converting the full-load power into operating power according to a target power conversion rate, wherein the target power conversion rate is a power conversion rate needing to be achieved by each target voltage converter, the power conversion rate is used for indicating an efficiency of converting, by the voltage converter, electric energy input to the voltage converter into electric energy input to the server;
calculating a target number according to the target power supply power and the operating power; and
obtaining the target number of target voltage converters from the plurality of voltage converters.
