Abstract

In order to provide a standard test set-up and method for the investigation of common-mode output noise produced by an adjustable speed drive (ASD), this paper evaluates the usability of the test method proposed in the EN55022/CISPR 22 standard for radio disturbance characteristics of information technology equipment. The behavior of output common mode noise is observed when parameters such as motor cable length, switching frequency and motor load are varied. Both common-mode current and common-mode voltage are measured, and the two methods are compared. It is concluded that the test method provided in EN55022/CISPR 22 can be used for measuring common-mode noise produced by an ASD.
