RESEARCH ON COMMON-MODE EMI IN THE THREE-PHASE CONTROLLED RECTIFIER

Weiming Ma

Abstract

The common-mode noise source of a three-phase controlled rectifier is modeled based on the principle of rectifier interference generating. Then the equivalent circuit is obtained from the measurement system which is set up according to the GJB152A-97. The common-mode interference current of a three-phase rectifier is calculated in frequency domain. The experiment results show the validity of the calculation.
