Abstract

High penetration of power electronics due to the concentration of switching frequency in the range of 9-150 kHz, may create new challenging issues. Currently, regarding the recent version standard (IEC 61000-6-3), there is a lack of enough insight and fundamental studies despite reported Electromagnetic Interference (EMI) noise problems in this frequency range. Hence, this paper
proposes a time-frequency analytical modeling method for characterizing Differential Mode (DM) noise in a single-phase Power Factor Correction (PFC) converter in this new frequency range. The provided comparative simulation analysis shows the proposed method's ability to estimate DM noise with a 9-150 kHz frequency range at high accuracy utilizing the double Fourier analysis
method. Moreover, the obtained experimental results on a 1 kW single-phase boost PFC converter validate the proposed EMI modeling approach's effectiveness, demonstrating an error of less than 1.8 dB for the considered experimental case studies.
