ABSTRACT:
A power supply module is configured for converting an AC voltage to a first DC voltage and applying the first DC voltage to a load. The power supply module includes a rectifying and filtering unit, a PFC unit, a voltage transforming unit, an input port, and a switch unit. The rectifying and filtering unit rectifies the AC voltage into a primary DC voltage and filters the primary DC voltage. The PFC unit corrects a power factor of the filtered primary DC voltage. The voltage transforming unit converts the corrected primary DC voltage and generates the first DC voltage for applying the load. The input port receives a first instruction or a second instruction and generates a first signal or a second signal, respectively. The switch unit establishes or disconnects an electrical connection between the voltage transforming unit and the load according to the first signal or the second signal.
