EnglishThis paper proposes high frequency (HF) modelling method of EMI filters for a 100 kW hybrid Si-SiC matrix converter used in aerospace application. The developed HF models are useful to make an accurate prediction of the effectiveness of the filters according to the standard for Airborne equipment and to improve the design in terms of size and lightness. Indeed lightness and compactness are important design constraints for aerospace systems but at the same time, the filter layout influences the values of the parasitic components. The method used to develop the HF models is based only on experimental measurements and it can be applied to different structures of filters without the knowledge of dimensions and electrical parameters of the single sections of the filter. In particular HF model of a differential mode input EMI filter and of a common mode and differential mode output EMI filter for matrix converters are developed in the frequency range 150 kHz-30 MHz. The circuit models are implemented in Matlab and Saber and are validated by comparing measured and simulated results. © 2013 IEEE.
