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 3):
The power factor correction circuit of  claim 1 , wherein the feedback signal corresponds to an output voltage of the power supply, the reference signal is a sawtooth wave signal, and the duty generator comprises:\n a feedback generator that is configured to generate the feedback signal; and a sawtooth wave generator that is configured to generate the sawtooth wave signal, wherein the duty generator is configured to generate the adjusted compensation signal by comparing the feedback signal to the sawtooth wave signal.
