Abstract :
A new AC-DC single-stage full-bridge PWM converter is proposed in the paper. The converter can operate with an excellent input power factor, continuous input and output currents, and has a bridgeless input that helps reduce conduction losses. In the paper, the basics of bridgeless AC-DC converters are briefly reviewed, the operation of the proposed converter is discussed, and experimental results that were obtained from a prototype and that confirm its feasibility are presented.
