摘要
建立了精确的仿真平台,以指导器件选型,评估低感膜电容和叠层母线排等技术,以及实现电动汽车逆变驱动系统的高功率密度及高可靠性。该平台严格按照实际工况来选择电路参数,器件本身及互连线的寄生参数也不能忽略。分析了电动汽车驱动系统的开关机制和寄生参数分布,详细介绍了仿真平台的建模和参数提取过程,实验结果验证了该仿真平台的有效性。
In order to guide the selection of power components, assess the new technologies such as low-inductive film capacitors and laminated bus bar,and in the end realize the high power density and reliability for electrical vehicle inverters,an accurate simulation platform based on Matlab/Sinlulink has been developed.Parameters of the simulation platform strictly accord with the practical working conditions,even parasitic existing in components and connections are also considered.This paper introduces the switching mechanism and the distribution of circuit parasitic.The system modeling and parameters confirmation of the simulation platform are presented.The experimental results are shown to verify the effectiveness of the simulation platform.
