To minimize the current stress of a dual active bridge (DAB) converter in its full power range, a global optimization strategy for the current stress under triple phase shift (TPS) control is studied. First, the operation principle and process of the converter under TPS control are analyzed, and a model of the relationship among its output power, current stress and phase-shift ratio is established. On this basis, the TPS control is optimized by seeking the optimal phase shift ratio combination with the goal of global minimization of current stress. In addition, the optimization results are compared with those under the dual phase shift (DPS) control in terms of current stress and reactive power. Finally, verification was performed by carrying out an experiment. The theoretical and experimental results show that the TPS control with the global optimization of current stress further reduces the current stress and reactive power in the full power range.
