摘　　要：对十二相电机的电压矢量进行了定义和计算,并分析了电压矢量的分布特点。提出了两种多Y型多相电机的整体SVPWM控制方法:最近两矢量SVPWM控制方法和最小开关次数SVPWM控制方法。分析了每种控制方法的实现方法、基本特点与特性,并进行了比较和仿真验证。The voltage vectors of 12-phase motor were defined and calculated, and the distribution characteristic of these vectors were analyzed. Two holistic SVPWM control methods of multi-Y motor were proposed. One was the nearest two vectors control methods and another was the least switch times control method. The realization method and basic characteristics were compared. The two methods were both verified by simulations.
