Resumé

Abstract—An optimized switching control scheme to reduce
the backflow power and the peak current of the dual active
bridge converter is presented in this paper. Based on a triplephase-shift modulation, the control scheme consists of operating
the switching devices with three optimized control variables on
the basis of achieving a decreased backflow power and peak
current. This can enhance the converter efficiency and reduce the
current stress on the switching devices. The optimal values of
these three manipulated variables are obtained through analysis
of different operation modes. Besides, the power transfer ranges
and soft-switching constraints are also explained in detail.
Experimental results are presented to validate the feasibility of
the proposed method
