摘　　要：变频调速在现代机械传动控制中应用越来越广泛 ,但变频器输入输出侧高次谐波所产生的电磁干扰对控制电路及周围电气设备的危害很大 ,有时甚至使控制系统无法正常工作 .本文从应用的角度出发 ,根据笔者实际使用的经验 ,简单阐述变频器高次谐波的产生及抑制的方法 .Frequeny varied speed regulation is gradually used abroad in modern machine driver control system. But the electromagnatism disturbances caused by high order harmonics of transducer are greatly harmful to electric devices and control systems around. Sometime it leads to whole system in disorder. The paper refers to analysis the high order harmonics of transducer and the ways to restrain it according to author's experience.
