| 摘 要： | 混合动力电动汽车(HEV)启动时,如果电动机可以负担启动的绝大多数能量,将减少内燃机在非最高效率点的工作时间,提高燃油利用率并且减少尾气排放。为了实现宽广的输出电压下的能量输出,提出了一种新的HEV用双向DC-DC拓扑,实现双向升降压的功能。针对具体的工作条件,设计了双向DC-DC拓扑参数,并且对所得的变流器进行了损耗分析。实验结果表明,此拓扑适合用于混合动力车的应用。

| Abstract: | To increase the fuel efficiency and reduce pollution emission at the time hybrid electric vehicle（HEV） car starts,HEV converter should have the ability to supply energy with low output voltage.A new bi-directional DC-DC converter was proposed for not only high output voltage but also low output voltage.The converter can work on both buck mode and boost mode to meet the varied output voltage requirement.Then,the parameters design of the converter was made with the detailed specification.And the loss distribution of the converter with different conditions was estimated.Finally,the efficiency of converter is verified in the experiments. |
