摘要
用计算机仿真技术分析了电压源脉宽调制(PWM)逆变器输出波形中的谐波消除法,给出了去除两个、四个及五个较低次谐波分量的解及波形,并把它们应用到一台典型的感应电动机上。最后进行了样机实验,结果证明是理想的。
By using the computer simulation technique, this paper deals with the method of eliminating harmonics in output waves of a voltage-source PWM inverter, gets the solutions without 2, 4 or 5 harmonic components, and apply them to a typical induction motor. Finally an experiment is made on a prototype and the satisfactory results obtained.
