摘要
This paper proposes a new ZCS non-isolated bidirectional buck-boost DC-DC converter for energy storage applications. The conventional bidirectional converter was derived with auxiliary resonant cell to obtain ZCS turn-on/turn-off condition of the main switches. The proposed converter was operated in boost and buck modes with soft-switching operations in order to minimize the current stresses and switching losses, because the resonating current for the zero current switching does not flow through the main switches. The converter has an improved overall efficiency than the hard-switching converter, for high power energy storage applications. This paper mainly describes the operation principles of the proposed topology and experimental verification of theoretical analysis of the simulation results.
