A new single-stage, single-switch power factor correction converter with output electrical isolation will be proposed in this paper. The topology of this converter is derived by combining a boost circuit and a forward circuit in one power stage. To improve the performance of the ac-dc converter (i.e., good power factor correction, low total harmonic distortion (THD) and low de bus voltage), two bulk storage capacitors are adopted. Its excellent line regulation capability makes the converter suitable for universal input application. Due to its simplified power stage and control circuit, this converter presents a better efficiency, lower cost and higher reliability. Detailed steady state analysis and design procedure will be presented. To verify the performance of the proposed converter, a design example along with P-simulation program with integrated circuit emphasis (PSPICE) simulation and experimental implementation will be given. The measured power factor and efficiency are 99% and 87% at low line (i.e., 110 VAC) operation, and 95% and 81% at high line (i.e., 220 VAC) operation, respectively.
