摘　　要：一定数量的多相电机通过适当的相序转换规则串联起来,使得该系统可以由1台逆变器供电而实现对所有串联电机的独立控制。以1台逆变器驱动2台双Y移30°永磁同步电机(PMSM)的串联系统为例,给出了串联系统的工作原理,为实现两电机的解耦运行,提出了一种新颖的SVPWM控制串联系统的方法。分析了SVPWM基本原理的具体实现方法。在Matlab/Simulink环境下,结合id=0的矢量控制策略,对电机的变载、变速运行进行了分析,验证了所提出的SVPWM控制策略的可行性。A number of multi-phase motors can be series connected and driven by a single inverter via the appropriate phase transformation rules, and all motors in series can be independently controlled. The working principle of two double Y shift 30° permanent magnet synchronous motor（PMSM） series system was proposed, a novel SVPWM method to achieve the decouple control was presented. The implementing method of SVPWM was analyzed. In Matlab/Simulink, the motor operating conditions,via id =0 vector control strategy, of variable load and speed were analyzed; the feasibility of the proposed SVPWM control strategy is verified.
