This paper discusses a novel approach to EMI filter design, based on parametric charts that allow to achieve optimal damping by matching the winding resistance of the damping inductor with the ratio between filter and damping inductances. The proposed approach simplifies the identification of the smallest commercial components complying with attenuation and efficiency requirements. Experimental results presented in the paper validate the proposed model and design method.

Abstract

This paper discusses a novel approach to EMI filter design, based on parametric charts that allow to achieve optimal damping by matching the winding resistance of the damping inductor with the ratio between filter and damping inductances. The proposed approach simplifies the identification of the smallest commercial components complying with attenuation and efficiency requirements. Experimental results presented in the paper validate the proposed model and design method.
