PFC BRIDGELESS POWER FACTOR CORRECTION CIRCUIT

摘要

The present invention relates to a bridgeless power factor correction (PFC) circuit for reducing a system cost. The bridgeless PFC circuit comprises: a first circuit including a first switch, a first capacitor, and an inductor sequentially connected to an alternating current (AC) power supply and including a first diode connected in parallel with the first switch and the first capacitor; and a second circuit including the inductor, a second capacitor, and a second switch sequentially connected to the AC power supply and including a second diode connected in parallel with the inductor and the second capacitor.
