Abstract：This paper studied the phase-shift angle selection of dual active bridge (DAB) converter. The adjustable range of the phase-shift angle is classified to ensure the current stress of DAB is minimized in condition of the identical transmission power. The reactive circulating current of the converter with phase-shift control is quantitatively analyzed, and the changing characteristics of the reactive power are researched. The battery charging and discharging management scheme using variable switching frequency DAB is proposed, to improve the efficiency of the converter and prolong the lifetime of battery. At last, a 2.5kW experimental platform is established and the experimental results prove the correctness of the theoretical analysis.
