摘　　要：为研究电压源型逆变器供电的六相感应电动机调速系统的性能,在六相感应电动机A-B-C坐标系动态数学模型的基础上,通过坐标变换得到六相感应电动机在d-q坐标系下的动态数学模型;采用空间矢量脉宽调制(Space Vector Pulse Width Modulation,SVPWM)技术对六相电压源型逆变器进行调制.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调速系统的仿真模型,进行调速系统起动和制动的动态仿真.仿真结果表明,系统的转矩脉动小,定子电流谐波小,具有较好的动态性能和稳态性能.In order to analyze the performance of the six-phase induction motor speed regulating system supplied with the voltage source inverter, the dynamic mathematical model of six-phase induction motor in the d-q coordinate system is got by coordinate transformation, on the foundation of the dynamic mathemat- ical model of six-phase induction motor in the A-B-C coordinate system. The Space Vector Pulse Width Modulation （SVPWM） is adopted to modulate the six-phase voltage source inverter. In the environment of MATLAB/SIMULINK, the simulation model of six-phase induction motor speed regulating system sup- plied with the SVPWM voltage source inverter is established, and the starting and braking processes of the six-phase induction motor are simulated. The simulation results show the advantages of the system： small torque ripple, small stator harmonic current, well transient response and steady response .
