Novel non-isolated LLC resonant converters

2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2012
In this paper, a novel non-isolated LLC resonant converter is proposed. This converter can achieve most merits of isolated LLC resonant converter, like zero voltage switching and very low turn off loss for all MOSFETs. By non-isolated technique, the turns of transformer can be largely reduced.
