摘　　要：变频器大多运行于恶劣的电磁环境，易受外界的一些电气干扰，同时其输入侧和输出侧的电压、电流含有丰富的高次谐波，对供电电网中其他电气设备也产生干扰。因此投入运行既要防止外界干扰它，又要防止它干扰外界，本文对变频器应用中的干扰原因和干扰信号传播途径进行了分析，并提出了相应的防治措施。Many Frequency Converters work in the harsh electromagnetic environment in which they are easily disturbed. At the same time higher harmonic wave, abound in the input side and output side of converter due to the electrical current and voltage, is certain to itifluence the other electrical equipments in the power supply network. Therefore, the mutual interference between the Converter and its environment must be avoided. This paper proposes the causes of interference and the propaganda ways of the interference signal, and some prevention measures are also introduced in this paper.
