摘要：

A bridgeless AC/DC converter for the power factor correction application is proposed in this paper. The diode bridge rectifier is removed in this converter by providing two separate paths of current for each half cycle of the AC voltage source; conduction losses are alleviated by decreasing the total number of switches in the conduction path of the current. In the proposed converter of this paper, switching losses are reduced by providing zero voltage switching (ZVS) condition for power MOSFETs using an auxiliary active clamp branch. By utilizing a series resonant circuit, zero current switching (ZCS) turn-off is achieved for output diodes, and the reverse recovery losses are eliminated.
