Abstract

Based on the principle of electromagnetic interfer-ence (EMI) filter inductance, this paper proposes a composite common and differential mode inductor integrated form filter structure, design principle of common and differential mode inductor, and design equations are derived for the precise design method of EMI filter, EMI filter designed in line with the national standard. The use of interference wave spectrum analysis equipment test before and after EMI filter insertion electromagnetic interference waveform, and insertion loss measurement curve, test results analysis based on waveform, verify the filter design method is correct and the feasibility of the application of filter.
