摘　　要：以中点箝位型三电平逆变器的基本拓扑结构为基础,分析了三电平空间电压矢量脉宽调制(SVPWM)的基本原理,提出了一种简化的扇区判断算法,并运用于三电平永磁同步电机矢量控制系统。利用MATLAB/Simulink软件对控制系统进行仿真分析,结果表明,系统具有较快的动态响应和稳定的静态性能。The fundamental principle of three-level space vector pulse width modulation（SVPWM） was analyzed based on the fundamental topological structure of the three-level neutral point clamped inverter.A simplified algorithm on the judgment of sector was proposed,applied to the SVPWM control system of the three-level permanent magnet synchronous motor.The control system was simulated with Simulink in MATLAB.Simulation results show that the system is in possession of rapid dynamic response and stable static performance.
