چکیده
A new bidirectional isolated Zero-VoltageSwitching (ZVS) DC-DC converter with nonpulsating input and output current is proposed. This converter is ideally suited for battery charging application and is applied as a submodule in a battery storage system based on a modular multilevel converter (MC). The current output of the proposed DC-DC converter enables small current ripple for directly interfacing a battery without the need of additional filter components. The derivation of topology, the operating principle, the analysis of the ZVS area as well as simulation results of a 12.4 kW DC-DC converter and a MC submodule are provided.
