摘　　要：多输入DC/DC变换器在混合储能中的应用非常广泛,也成为近年来的研究热点。对所提出的三全桥双向DC/DC变换器进行了深入的理论分析,通过数学模型的推导,得出稳定情况下输入、输出电压、功率大小与移相角之间的关系。在Boost模式下对软开关的性能进行了分析,最后研制了一台1.2 kW的样机,进行上述分析的实验验证。Multiple Input DC/DC converter attracts wide attention in recent years.It is applied on hybrid energy storage system for the electrical vehicle and distributed renewable energy system.The theoretical analysis on triple active bridge DC/ DC converter is proposed,by the deduction of mathematical model,the input/output voltage,power size and phase-shift angle of the relationship are concluded with the stable condition.The characteristics of soft-switching in Boost are proved by the experimental results which offered by a prototype of rated 1.2 kW.
