POWER SUPPLY DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/017563
Kind Code:
A1
Abstract:
The embodiments of the present application provide a power supply device and a control method. The power supply device comprises a first alternating-current (AC)/direct-current (DC) unit and a second AC/DC unit, an input end of the first AC/DC unit and an input end of the second AC/DC unit are connected to an AC input bus, an output end of the first AC/DC unit is connected to a first DC output bus, the output of the first AC/DC unit is stable, and an output end of the second AC/DC unit is connected to a second DC output bus. Power is outputted to a plurality of DC output buses by means of a plurality of AC/DC units, so as to be supplied to different loads respectively, corresponding bus voltages can be configured for different loads, and the boost requirements of different loads are satisfied. The power supply device further comprises bidirectional DC/DC units and a power backup unit, the bidirectional DC/DC units are connected between various DC output buses, and an output end of the power backup unit is connected to the first DC output bus, so that unified power backup and unified management can be achieved.
