Analysis of a Novel Soft Switching Bidirectional DC-DC Converter

Abstract

In this paper, a novel bidirectional DC-DC converter employing soft switching technique was proposed. Compare to conventional bidirectional converters, the main switches of proposed converter are operated without switching losses. Moreover, auxiliary switches are used, and the switches are operated under zero voltage switching (ZVS) and zero current switching (ZCS) condition. To verify the validity of the proposed converter, mode analysis, design procedure, simulation and experimental results are presented.

“…The use of a higher switching frequency results in higher switching losses, resulting in a lowered efficiency. However, this switching loss can greatly be reduced by the soft-switching technique [2]- [6]. The zero-voltage switching (ZVS) technique is one of the soft-switching techniques.…”
