摘　　要：针对最常见的交流电机系统,以系统级串联和并联的思路,介绍了串联型拓扑集成和并联型拓扑集成两大方法.在串联型集成方法上,以开绕组电机驱动为基础,介绍了适用于调速范围拓展和容错的串联绕组拓扑及悬浮电容拓扑等.在并联型集成方法上,介绍了常规多相电机驱动、逆变器并联驱动三相电机及多模块电机驱动等技术,实现容错、电磁兼容和振动的改善.最后,针对以磁悬浮轴承为代表的特种电机,介绍多自由度电机和控制器集成的特殊方法.这几个案例说明:结合电力电子和电机的特点进行自由度的组合,可以更有效地改善电机系统的综合性能,实现电力电子化电机系统的真正集成.For the regular alternating current motor system,based on the idea of system-level series and parallel connection,the two families of methods for series integration and paralleled integration was introduced.For series integration,based on open-winding motor drives,the series winding topologies and floating capacitor topologies which are suitable for wide speed range and faulttolerant control were introduced.For the paralleled integration,regular multi-phase motor drives,paralleled inverters and multisegment motor drives were introduced,improving the fault-tolerance,electromagnetic compatibility and vibration.Finally,for special kinds of motors including magnetic bearings,the special integration methods for multi-freedom actuator and controller were introduced.These examples have proved that,combing the freedoms of power electronics and motors,the performance of the electrical machine system can be improved more efficiently and realize the integration of power electronics-lized motor system.
