摘要
文中主要针对混合电动汽车电力系统中的DC-DC直流变换器进行了研究,对设计出的移相全桥倍流整流DC-DC直流变换器的拓扑结构进行了理论分析,对同步整流进行了详细描述,列出了模型的仿真结果。通过对模型的仿真结果与理论分析结果相比较可知,仿真结果与理论分析结果基本一致。基本可以得出该DC-DC转换器建立的模型是正确的。
This paper mainly designs DC-DC converter according to the theory of HEV power system.The phase-shifted fullbridge,current doubler rectifier DC-DC converter is analyzed and the state space equations of all the phase are listed. The synchronous rectifier is carried on the detailed description.Compared with the theoretical analysis results,the simulation results and theoretical analysis results are basically identical. It concluded that the DC-DC converter model is correct.
