摘　　要：建立六相感应电动机在两相同步旋转d-q坐标系下的动态数学模型,并分析六相电压源型逆变器的空间矢量脉宽调制(SVPWM)技术。在MATLAB/SIMULINK环境下,构建SVPWM电压源型逆变器供电的六相感应电动机的仿真模型,分别进行六相感应电动机能耗制动、反接制动和回馈制动的动态仿真,并分析这三种制动方式的特点,为电力传动系统的设计提供理论依据。The dynamic mathematical model of six-phase induction motor based on d-q coordinate system is established, and the space vector pulse width modulation （SVPWM） of six-phase voltage source inverter is analyzed. In the environment of MATLAB/ SIMULINK, set up the system simulation model of six-phase induction motor supplied by the voltage source inverter ; then simulate the dynamic braking, reverse braking and regenerative braking processes of the six-phase induction motor separately, and analyze the characteristics of these three braking modes. The proposed simulation method can be used f^or providing the theoretical basis for the design of electdc drive system.
