 Abstract

This study presents a single-phase power factor correction AC?DC converter that operates in discontinuous conduction mode. This converter uses the pulse-width modulation technique to achieve almost unity power factor and low total harmonic distortionof input current for universal input voltage (90 Vrms to 264 Vrms) applications. The converter has a simple structure and electricalisolation. The magnetizing-inductor energy of the transformer can be recycled to the output without an additional third winding. The steady-state analysis of voltage gain and boundary operating conditions are discussed in detail. Finally, experimental resultsare shown to verify the performance of the proposed converter.
