摘要

本文研究了调速电机驱动系统中固有的电磁干扰问题。电磁干扰问题主要源于电压源脉宽调制(PWM)逆变器输出端出现的共模电压阶跃变化。本文介绍了一种小型无源电磁干扰滤波器作为解决电磁干扰问题的实用方案，以及它的工作原理和性能。

Influence of high dv/dt switching on a motor drive system: a practical solution to EMI issues

This paper deals with electromagnetic interference (EMI) issues inherent in adjustable-speed motor drive systems. The EMI issues mainly stem from a step-like change in the common-mode voltage appearing at the output terminals of a voltage-source pulse-width-modulation (PWM) inverter. This paper describes a small-sized passive EMI filter as a practical solution to the EMI issues, along with its operating principles and performance.
