Abstract

A new AC/DC power converter with high power factor is presented. This power converter has the advantages over both standard two-stage power factor corrected AC/DC power converters and single stage PFC power converters. These advantages are the overall simplicity of the power train, an optimised steady DC voltage maintained across the DC cell, constant operating frequency, inherent inrush current limiting capability, high efficiency due to the chosen topology´s inherent ZVT capability and simple and inexpensive control circuits. The principle of operation is discussed and the design procedure for the power mesh is proposed. The small-signal model of the PFC cell is included
