Based on a Modified SEPIC Converter with Low Voltage Stress
نویسنده
چکیده
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 voltageand current-stress compared to other PFC topologies. The PFC SEPIC converter also has the advantage of the continuous input current but suffers from high voltageand 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 200W prototype for 185-270 V line voltage will also be presented.
