摘　　要：双向DC/DC变换器是复合电源系统中非常重要的组成部分之一,尤其在车载复合电源系统大功率变换工况下,双向DC/DC变换器开关频率高、损耗以及拓扑控制更为复杂。针对这一缺陷,结合复合电源系统能量管理策略,提出一种面向复合电源系统应用的四象限能量双向流动的DC/DC变换器拓扑结构,搭建了以四象限拓扑结构为导向的复合电源系统双向DC/DC变换器实验环境,实验结果表明,该拓扑结构损耗小,能够实现冗余控制,提高了系统的可行性及能量转换效率。The bi-directional DC/DC converter is one of the very important part of hybrid energy storage system,especially in large power vehicle hybrid power supply system transformation under the condition of bidirectional DC/DC converter with high switching frequency,loss and topology control is more complex,In order to solve this problem,an energy management strategy for hybrid power system combining with the ESMP full bridge bidirectional DC/DC converter topology,building an experimental environment based on full bridge topology oriented hybrid energy storage system with bidirectional DC/DC converter,experimental results show that the topological structure of small loss and redundancy control,improve the feasibility of the system and the efficiency of the energy convert.
