摘要：

This paper presents a single-stage isolated converter topology designed to achieve a regulated de output voltage having no low-frequency components and a high-input power factor. The topology is derived from the basic two-switch forward converter, but incorporates an additional transformer winding, inductor, and a few diodes, The proposed circuit inherently forces the input current to be discontinuous and ac modulated to achieve high-input power factor. The converter output is operated in discontinuous mode to minimize the bulk capacitor voltage variations when the output load is varied, Analysis of the converter is presented, and performance characteristics are given. Design guidelines to select critical components of the circuit are presented, Experimental results on a 150-W 50-kHz universal input (90-265 V) 54.75-Y output ac/dc converter are given which confirm the predicted performance of the proposed topology.
