Abstract

Electromagnetic interference (EMI) noise is defined as an unwanted electrical signal that produces undesirable effects in a control system, such as communication errors, degraded equipment performance and malfunction or nonoperation. This article provides a common understanding of the EMI issues and provides simple pre-installation and post-installation guidelines useful for all interested parries involved in the industry application of adjustable speed PWM invertor-fed AC motor drives
