SVPWM Based Speed Control of Induction Motor Drive with Using VF Control Based 3-Level Inverter
目前,感应电动机是各行业的主导传动装置。与直流电动机相比,感应电动机动态响应差,控制起来相当麻烦。在电压型逆变器中,通过对逆变器开关矢量的优化选择,可以直接控制定子磁链和电磁转矩。本文应用空间矢量脉宽调制(SVPWM)技术,对采用V/F方法的IM驱动器进行了建模,更好地理解V/F方法及其难点。采用三电平逆变器,可以减小转速和转矩波动。然后利用电压矢量调制器实现参考电压矢量。在实例分析的基础上给出了大量的仿真结果。
