Abstract:
A power factor correction circuit corrects a filter current flowing through a filter capacitor asymmetrically based on a peak of an input voltage by controlling a switching operation of a power switch, thereby correcting distortion of an input current.

Claim (Index 19):
A power factor correction circuit comprising:\n a differentiator that is configured to receive an input detection voltage that corresponds to an input voltage of a power supply and to differentiate the input detection voltage to generate a differentiated signal; and a duty generator that is configured to receive an adjustment signal that is based on the differentiated signal, to generate a compensation signal by comparing a feedback signal with a reference signal, to generate an adjusted compensation signal by adjusting the compensation signal using the adjustment signal, and to turn off the power switch in accordance with the adjusted compensation signal.
