Title

Single-switch ac/dc converter with power factor correction

Abstract

A new single-switch, one-stage power factor correction converter with output electrical isolation will be proposed in this paper. Its steady state analysis and design procedure are presented. The configuration of this converter is achieved by combining a boost circuit and a forward circuit in one power stage. To relieve the voltage spike caused by the leakage inductance of the power transformer, two bulk storage capacitors are adopted. Due to its simplified power stage and control circuit, this converter presents a better efficiency (87%), lower cost and higher reliability. Detailed steady state analysis results show that the proposed converter has both good power factor correction and excellent line and load regulation capabilities. To verify the performance of the proposed converter, a design example is given with its PSPICE simulation and experimental results, measuring power factor of 0.99.
