Abstract The soft-switching conditions and the operation stages of dual active bridge DC-DC converter are analyzed. Optimized parameters of DAB converter are proposed which meet requirements of zero-voltage-switching under the control of dual-phase-shifting. The method of combining optimized parameters with limited dead time is proposed to reduce switching power dissipation and raise efficiency based on analysis of mathematical model of each steady-state operation. At last, the effectiveness of optimization of parameters are validated by experiments based on an experimental prototype, and experimental results also verify the effectiveness of the points proposed in the paper.

Key words： Dual-active-bridge DC-DC converter dual-phase-shifting control zero-voltage- switching dead time efficiency
