Abstract

In this paper, the high efficiency isolated bidirectional AC-DC converter system with several improved techniques will be discussed to improve the performance of a low voltage DC distribution system. In order to increase the efficiency of the non-isolated full-bridge AC-DC rectifier, the switching devices are designed by using IGBTs without an antiparallel diode, MOSFETs, and SiC diodes. Through the analysis of operational modes, each switch is selected by considering switch stresses. Finally, design guides and gain characteristics of the bidirectional full-bridge CLLC resonant converter with the symmetric structure of the primary inverting stage and secondary rectifying stage will be discussed for low voltage DC distribution system. Experimental results will verify the performance of the proposed methods using a 5kW prototype converter.
