Abstract

The introduction of modified Smith-Wijn winding into the Common Mode Choke has shown its advantages in comparison to the regular Common Mode Chokes only in the region of high frequencies. Unfortunately we haven’t received the expected results in the operational region of currently used EMI filters. Paper represents a new approach of enhancing EMI filter high frequency noise suppression, there are presented several experimental results of the proposed technique. Better results are achieved at frequencies from 150MHz up to the 450MHz with average improvement of noise suppression around 10dB. A new task has been assigned in order to improve the electromagnetic filter efficiency – optimizing the compound of EMI filters. Ill.10., bibl.8 (in English summaries in English, Russian and Lithuanian).
