EMI modeling method of AC-AC power converters

摘要

References(7) This paper presents a new model for simulation of Electromagnetic Interference (EMI) in power converters. Despite the fact that a Matrix Converter (MC) has been selected, such methodology can be applied to other converter topologies. The EMI model relies on a combination of time and frequency domain techniques in order to not only reduce the computational complexity but also to avoid convergence problems. Common Mode (CM) leakage current, which lays basically in A band (10kHz to 150kHz), is simulated and such results are compared with those obtained from the MC prototype showing a good concordance in terms of peak value.
