Analysis and synthesis of novel hybrid integrated soft-switching cells for power converter systems with two switching poles

This paper proposes a methodology for developing integrated auxiliary soft-switching cells for power converter systems with two or more switching poles. The integrated cells obtained are a combination of cells from the same soft-switching technique or even of cells from different techniques, giving rise to hybrid cells. The resulting cells have fewer components, are lighter, and have a smaller volume than the conventional ones. Experimental results from a 1-kW power converter with two switching poles are presented to demonstrate the proposed methodology.
