Abstract
A power supply device includes a transformer, a first rectifier, a first voltage conversion module, a second voltage conversion module, and a control unit. The first rectifier, connected to a primary winding of the transformer, converts a received alternating-current voltage to a first direct-current voltage. The first voltage conversion module is connected to the first secondary winding of the transformer. The second voltage conversion module is connected to the second secondary winding of the transformer. The control unit, connected to the first voltage conversion module and second voltage conversion module, controls the first voltage conversion module or second voltage conversion module to adjust an output voltage or an output current of the power supply device.
