© 2016 IEEE. Conventional soft switching techniques are promising for improvement of efficiency in full bridge converters. However, efficiency of converters with employing such techniques is restricted due to narrow range of zero voltage switching (ZVS). In such situation, several methods have been proposed in the literature to cope with wide range of ZVS from no load to maximum load. The extra circuitry added to achieve a wide range of ZVS generates more conduction losses in a converter and increase cost of converter. In this paper, a novel ZVS full bridge converter is proposed to eliminate limitations of narrow range ZVS, improved efficiency and reduced cost. The circuit diagram, operation principle of proposed converter is explained and analyzed theoretically in detail. In addition, the proposed converter is built and experimental results are provided to verify the novel ZVS full bridge converter.
