| 摘 要： | DC/DC变换器是复合电源电动汽车的重要组成部分之一,为了提高DC/DC变换器的功率密度,DC/DC变换器正在向高频化发展,研究在单相DC/DC变换器的基础上,设计了一种三重交错并联DC/DC变换器,可以提高系统的开关频率、降低纹波电压,从而减小滤波器的体积、提高功率密度.最后通过Simulink进仿真分析,结果表明:三重交错并联DC/DC变换器的纹波电压明显小于单相DC/DC变换器,有利于功率密度的提高.

| Abstract: | DC/DC converter is the important part of composite power electric cars. In order to improve the power density of DC/DC converter, high frequency is required. This paper designs a triple inter/earing DC/DC converter based on the single phase DC/DC converter. It can reduce the ripple voltage effectively, reduce the volume of the filter and improve the switch frequency of the system. Finally, through the simulation analysis, the results show that the system efficiency of the triple interleaving DC/DC converter is better than the single phase DC/DC converter, thus the power density is increased. |
