SWITCHING METHOD AND MULTI-INPUT POWER SYSTEM

The embodiments of the present disclosure provide a switching method and a multi-input power system, where the method is used to control an input power source connected with N power supply units, and N is greater than 1, and the method includes: determining a switching strategy for each power supply unit, where the switching strategy is used to indicate a moment when input of a power supply unit is switched from an auxiliary input power source to a main input power source; switching, according to the switching strategy, the input of each power supply unit from the auxiliary input power source to the main input power source at the moment indicated by the switching strategy, where the main input power source includes a standby power source.
