Abstract :
A new low conduction loss, low cost zero-voltage-transition (ZVT) power factor correction converter (PFC) is presented. The conventional PFC which consists of a bridge diode rectifier and a boost converter (one active switch) always has three semiconductor conduction drops. The two switch type PFC which was presented reduces conduction loss by reducing one conduction drop but the cost is increased because of one additional switch. The proposed PFC reduces conduction loss with one switch. Conduction loss reduction is a little bit less than that of the two switch type, but it is achieved with low cost. Operation, features, and characteristics are comparatively illustrated and verified by the experimental results from a 2.5 kW, 100 kHz laboratory prototype
