چکیده
An analysis of a dual active bridge (DAB) converter under soft-switching mode in the whole operating range is presented in this paper. A detailed study of the impact of the transformer magnetizing inductance, LM , and snubber capacitance, Cxx, parameters on the soft-switching regions is carried out to obtain some design considerations. Simulation and experimental results which validate the theoretical analysis are also presented. Keywords— dc-dc converters, dual active bridge converter, soft switching, modulation strategy.
