摘　　要：针对双向DC/DC变换器采用双重移相控制时实现软开关和完全消除回流功率存在矛盾的问题。在分析了软开关约束条件和传输功率及回流功率与内外移相角的关系后,提出一种在给定变换器传输功率下既满足软开关约束条件,同时又对回流功率进行优化控制的双重移相控制策略。最后通过MATLAB/Simulink仿真,验证了所提控制策略的正确性和有效性。For the contradictory problems of the bi-directional DC-DC converter based on dual-phase-shift control to achieve soft switch and eliminate reflux power completely, this paper analyzed the relationship between the soft switch constraints, transmission power,the reflux power and the inside and outside phase-shifting angle,and put forward a control strategy of dual-phase-shifting which has given transmission power and meets the soft switch constraints aimed to optimize the reflux power. Finally, through the MATLAB/Simulink it verifies the correctness and effectiveness of the proposed control strategy.
