摘　　要：车用电机驱动系统是新能源汽车的三大关键技术之一,要求更高的性能、体积/重量密度及环境温度。与国际先进车用电驱系统发展水平相比,我国在功率密度、可靠性及成本三方面仍存在较大差距。这里对车用电机控制器关键技术进行研究,包括考虑主要寄生参数的功率主回路建模、智能功率模块I(PM)研发和新型膜电容应用研究,着力解决车用电机控制器技术瓶颈。在上述研究基础上开发出高功率密度车用电机控制器,测试结果表明该控制器的重量比功率为8 kW.kg-1,体积比功率为10 kW.L-1。Motor drive system is one of the three key technologies in electric vehicle, requiring higher performance, higher volume/weight of higher density,higher temperature.Compared with the international advanced level of development of drive systems, mainly in the power density, reliability and cost, China still has a wide difference.This paper describes some key technologies,including the PSpice model of VSI with major parasitic parameters, development of intelligent power module （IPM） and application of new film capacitor.Finally based on the studies carried out to develop high power density inverter, experimental results show that the inverter has the peak power at 8 kW.kg^-1, and volumetric power density at 10 kW.L^-1.
