Extended Phase Shift Control in Dual Active Bridge Converter Considering Magnetizing Inductance of Transformer

The single phase shift (SPS) method is the conventional switching strategy for the dual active bridge (DAB) structure. Another switching method is the extended phase shift (EPS) method. In this modulation, the zero voltage switching (ZVS) range increases. In this paper, the effect of the magnetizing inductance of the transformer on the output power value and ZVS range with the EPS control method is studied. Simulation results show correctness of the theoretical analysis.
