摘要
从SVPWM(空间矢量PWM)波产生的机理出发 ,通过仿真研究了三种主要逼近方法下的SVPWM波谱的谐波分布和相应逆变器产生电压的谐波分布情况 ,并总结出了各自的优缺点。基于仿真研究还分析了谐波对交流感应电机电磁转矩的影响 。
In this paper , three kinds of approaching models are studied for control principles of SVPWM. Their harmonics components and switching frequency are investigated by analysis and simulation. The merits and demerits of various approaching modes are presented. A new thought is proposed by analysis and simulation of the influence of harmonics on electro-magnetic torque.
