Validation of EMI model for matrix converters

Abstract

This paper is focused on the validation of a previously presented method to obtain conducted EMI in direct matrix converters (MC). Such model is based on a frequency domain equivalent circuit, which is applied to two different prototypes of MC in order to validate such method. This paper starts with a review of the EMI method and follows obtaining the equivalent circuit. The experimental part consists of a comparison between EMI simulation results and measured EMI in two different MC. Finally, the paper includes a discussion on the method generalisation.
