Abstract
An embodiment method for controlling a power factor correction circuit includes detecting an AC zero voltage crossing point, detecting a current flowing through an inductor, and reducing a distortion of the current flowing through the inductor by determining a current at the AC zero voltage crossing point as a resistive current, an inductive current, or a capacitive current and controlling each of a plurality of switching elements from a time point when the AC zero voltage crossing point is detected based upon a result of determining the current.
