摘要
本文分析了变频器整流系统的干扰源性质，通过理论分析和仿真验证，给出实际选取滤波电容定量的依据，同时本文还对施加滤波技术抗干扰进行了测试分析。测试结果表明，在20MHz附近干扰信号幅度减少了10dB．为变频器的电磁兼容设计提供了可靠的理论和实验依据。
This paper analyzes the electromagnetic interrupt of rectifier system of transducer. It is provided the quantitative bases for choosing capacitor filter. It is proved that the amplitude decreases by lOdB at around 20MHz by taking filtering technique measures. The results provide reliably theoretical and experimental basis for the EMC design of transducer.
