This study proposes a novel design of soft-switching based bidirectional converter for the applications in energy storage systems. By implementing an additional auxiliary circuit to the conventional non-isolated converter, the proposed converter inherits better efficiency with minimised turn-on losses. Moreover, auxiliary switching devices are also soft-switched. This converter can be operated at high power outputs through ZVS turn-on operation. The operation principle, design analysis and experimental results are reported to validate its main features in the study. Furthermore, the performance of this converter is analysed on a 1 kW laboratory prototype for both boost and buck modes.
