Abstract
A power supply device includes first and second power factor correctors, and first and second resonant circuits. The first and second power factor correctors are for receiving an alternating current (AC) input voltage, and are driven by first and second driving signals for rectifying the AC input voltage to generate first and second driving voltages, respectively. The first and second resonant circuits are coupled to the first and second power factor correctors for receiving the first and second driving voltages, respectively, and have output sides that are coupled in parallel for outputting an output voltage. The first power factor corrector and the first resonant circuit in combination is parallel-connected to the second power factor corrector and the second resonant circuit in combination.
