摘　　要：基于电感电流有效值最优化控制,提出一种新的软开关范围最优化控制策略。该控制策略通过限制开关管动作时的电感电流,既保证了整个功率区间上极大地扩展了软开关范围,减小了开关损耗,同时又具有准最优电流有效值,可进一步提高DAB变换器的效率。同时提出一种新的发波方式,实现桥臂之间的热均衡,最后利用MatLab搭建仿真模型并进行验证。Based on the optimization control of inductive root mean square current,a new soft-switching range optimization control strategy is proposed.This control strategy restricts the inductor current during switch action,ensuring a significant extension of the soft switching range across the entire power range,reducing switch losses,and achieving accurate root mean square current,thereby further enhancing the efficiency of the DAB converter.Meanwhile,a new modulation method is proposed to achieve thermal balance between bridge arms.Finally,a simulation model is built and verified using Matlab.
