N2 - Dual-Active-Bridge (DAB) DC-DC converter are widely used in energy conversion for its attractive features such as reduced weight, high power density and bidirectional energy flow. The traditional control strategy of DAB faces the problems of large current stress, resulting in low efficiency and slow transient response. This paper proposes an optimal control strategy based on dual-phase-shift (DPS) control, which can minimize the current stress of DAB with wide range of input and output voltages by calculating the optimal phase shift angles. In this way, the current stress will be decreased significantly, especially when the system works in light-load state. Meanwhile, to improve transient response, the direct power control strategy is adopted, which takes capacitance current into consideration. Finally, the simulation results validate the superiority of the proposed DPS control strategy.
