Abstract
The present invention provides a nitride-based power factor correction (PFC) circuit for improving power distribution efficiency from an AC power supply to a load. The PFC circuit comprises a nitride-based bidirectional switch and a controlling circuit having a first switching node and a second switching node electrically coupled to a first control terminal and a second control terminal of the bidirectional switch respectively. The provided nitride-based PFC circuit has high efficiency over a broad range of input voltage, a simpler circuit topology with smaller component size.
