摘要
在PWM变频控制理论的基础上,对现阶段广泛应用的调制方法输出的波形进行了谐波分析,以此讨论了谐波产生的各种因素,并对应提出一种有效的抑制方法来实现减小谐波对电机的危害。
Based on the theory of frequency conversion technique by P W M, this paper makes harmonic analysis of output of inverter by different control modes, which are applied widely nowadays, in order to discuss actors to effect the altitude and frequency of harmonic, and then accordingly suggests an effective method to restrain the harmonic which is harm to motor.
