To improve the dynamic response performance of a dual active bridge (DAB) converter with dual phase shift(DPS) control during load switching and reduce the current stress, a novel dual phase shift (NDPS) control method is studied. By changing the shifting direction of the internal phase shift angle in traditional dual phase shift (TDPS), the relationship between the transmission power and phase shift ratio is reconstructed, and the adjusting range of phase shift ratio is extended. The solving method for the optimal phase shift ratio of DPS control under the condition of current stress minimization is studied, and the dynamic response characteristics of NDPS and TDPS control under load switching conditions are compared and analyzed. Finally, an experimental platform of DAB converter was built to verify the theoretical analysis, and experimental results show that the optimal phase shift ratio combination based on current stress minimization can effectively reduce the current stress under light load conditions. At the same time, NDPS control has better dynamic response characteristics than TDPS control.
