Abstract: This application provide a power supply device and a control method. In one example, a power supply device includes a first AC/DC unit and a second AC/DC unit. An input terminal of the first AC/DC unit and an input terminal of the second AC/DC unit are connected to an alternating current input bus. An output terminal of the first AC/DC unit is connected to a first direct current output bus. The first AC/DC unit is output stable. An output terminal of the second AC/DC unit is connected to a second direct current output bus. Power is output to a plurality of direct current output buses respectively through a plurality of AC/DC units to supply power to different loads.
