Abstract

The boost topology is often the designer´s first choice when dealing with PFC front-ends. This topology is well documented in the literature and has obvious advantages like continuous input current and low voltage- and current-stress compared to other PFC topologies. The PFC SEPIC converter also has the advantage of the continuous input current but suffers from high voltage- and current stress. In this paper a modified SEPIC converter is presented with reduced voltage stress, comparable to that of the boost converter. Experimental result of a 200 W prototype for 185-270 V line voltage are also presented
