The control method is implemented as follows: the first power supply is used as the frequently-used power supply and the second power supply is used as the standby power supply; when a voltage detection module detects that the frequently-used power supply and the standby power supply both have power, a micro-processing controller preferentially chooses a first circuit breaker to be switched on, and a load is powered by the frequently-used power supply; when the frequently-used power supply is in failure, the first circuit breaker is controlled by a no-voltage tripping mechanism of the first circuit breaker to be tripped; after a certain delay which is calculated by an internal clock of the micro-processing controller, the micro-processing controller controls the second circuit breaker to be switched on, and the load is powered by the standby power supply; when the frequently-used power supply is restored to supply power, the micro-processing controller controls the second circuit breaker to be switched off; and after a certain delay which is calculated by the internal clock of the micro-processing controller, the micro-processing controller controls the first circuit breaker to be switched on, and the load is powered by the frequently-used power supply again. By adoption of the control method, the problem that the currently processed information of a computer is damaged or lost when the power supply is interrupted can be solved.
