Abstract
A power factor corrector correcting the power factor of an alternating current (AC) voltage is disclosed. A power factor correcting unit corrects the power factor of the AC voltage. A smoothing unit smoothes a power factor corrected voltage and includes a film condenser and a plurality of electrolytic condensers. A rectified voltage is applied to one end of an inductor. One end of a switch is connected to the other end of the inductor, and the other end of the switch is earthed. One end of a diode is connected to one end of the switch. One end of a film condenser is connected to the other end of the diode, and the other end of the film condenser is earthed. An electrolytic condenser is parallel-connected to the film condenser.
