Abstract
A power control circuit includes an alternating current (AC) power source, a rectifier and a valley-fill circuit. The AC power source is configured to receive an AC voltage. The rectifier is configured to convert the AC voltage into a rectified voltage. The valley-fill circuit includes: an inductor, having a first terminal coupled to the rectifier, and a second terminal; a first resistor, having a first terminal coupled to the second terminal of the inductor, and a second terminal; a diode, having a cathode coupled to the second terminal of the inductor, and an anode; and a first capacitor, having a first terminal coupled to the second terminal of the first resistor and the anode of the diode, and a second terminal coupled to ground.
