Abstract
The present application provides a power supply device compatible with AC/DC input and a control method thereof, the device comprising a power factor correction circuit, a direct current-to-direct current (DC/DC) circuit, a bypass circuit, an input sampling circuit, and a controller. The power factor correction circuit is connected to the DC/DC circuit. The bypass circuit is connected to a boost circuit input end of the power factor correction circuit and an input end of the DC/DC circuit. The controller is connected to the input sampling circuit and the power factor correction circuit respectively, for controlling the power factor correction circuit to stabilize the output voltage within a preset range according to an input signal collected by the input sampling circuit, or turning off the power factor correction circuit and providing power for the DC/DC circuit via the bypass circuit.
