POWER SOURCE DEVICE AND CONTROL METHOD FOR POWER SOURCE DEVICE

WIPO Patent Application WO/2023/201940

A1

A power source device and a control method for a power source device. The method comprises: when a first input power source (20) supplies power, detecting whether there is an exception in the first input power source (20); and when there is an exception in the first input power source (20), controlling a first access point of a first relay (S1) and a third access point of the first relay (S1) to be disconnected, a second access point of the first relay (S1) and a fourth access point of the first relay (S1) to be disconnected, a common access point of a third relay (S3) and a second access point of the third relay (S3) to be connected, a common access point of a fourth relay (S4) and a second access point of the fourth relay (S4) to be connected, a first access point of a second relay (S2) and a third access point of the second relay (S2) to be connected, and a second access point of the second relay (S2) and a fourth access point of the second relay (S2) to be connected. By means of the present application, the problem in the related art of the relatively high cost caused by the fact that a two-way redundant power supply mode is used and in the two-way redundant power supply mode, two sets of power source devices need to be configured is solved.
