A Simplified Prediction Method for EMI Generated by Three-phase PWM Rectifier

摘要：

A simplified method for the calculation of Commonmode (CM) electromagnetic interference (EMI) caused by Three-phase PWM rectifier is presented. EMI analysis in time domain presents particular problems due to complex geometry and the wide range of time constants involved. This makes the simulation of EMI a complex matter. The method presented here is based on a Matrix representation process and is specially designed to simplify the mentioned problems. In this paper, quick and robust simulations were preferred rather than very accurate results. Once the disturbances sources are calculated parameters of the propagation path can be changed giving a new prediction immediately. To evaluate the performances of this analytical approach the frequency-domain model is compared with Saber simulations.
