车用高性能永磁电机驱动系统的研发

摘要

重点介绍高性能车用永磁电机驱动系统中的高功率密度车用电机控制器、广域高效混合励磁电机和全数字化高性能电机控制软件平台3项关键技术,提出了在功率密度、全范围效率、可靠性、维护性和成本等方面均优于传统的车用永磁电机驱动系统的解决方案.在此基础上开发出高功率密度车用电机驱动系统样机,成功应用于力帆LF620纯电动警务车,并服务于2010年上海世博会上.%Three key technologies of high performance permanent magnet motor drive system, including the high power density inverter, compound excited motor with high efficiency in wide speed range, and fully digital control software are emphatically presented. A solution scheme for vehicle permanent magnet motor drive system is proposed , which is superior to conventional one in respects of power density, full range efficiency, reliability, maintainability and cost. On these bases a prototype of high power density permanent magnet motor drive system is developed and applied to LF620 electric police car, which provided service in 2010 Shanghai World Expo.
