摘要：

This paper presents a front-end converter including a novel bridgeless PFC converter with high reliability and an isolated full-bridge DC-DC converter with a proposed control scheme to improve efficiency under a light load condition. The proposed bridgeless PFC converter can avoid flowing a high inrush current to silicon carbide Schottky diodes and MOSFETs without impairing efficiency. Furthermore, efficiency of full bridge DC-DC converters under a light load condition can be improved by adjusting to proper switching frequency. In this paper, the proposed topologies and the principles of operation are introduced. Furthermore, a 2kW prototype was built in order to evaluate the proposed topologies. The experimental results are shown in this paper.
