A bridgeless dual boost rectifier is proposed to achieve a soft switching for power factor correction circuit. Based on the conventional bridgeless dual boost rectifier, an auxiliary circuit is employed in the proposed converter to perform zero-voltage switching of the main switches and zero-current switching of the auxiliary switches. As a result, switching losses can be significantly reduced. In addition, the design guideline for the optimized turn-on time of the auxiliary switches is presented to minimize the additional conduction loss in the auxiliary circuit. The validity of the proposed converter is confirmed by the experimental results of a prototype converter with 100-240 V-AC universal-line input and 800-W (400 V/2 A) output.
