An Influence of Parasitic Parameters on Electromagnetic Disturbance Emission in Voltage Converters

摘要

In this paper it is estimated an influence of parasitic parameters of elements in converters of different topologies on a spectral components of conducted electromagnetic interference. Scalability of obtained results allows to estimate expected levels of electromagnetic interferences (EMI) from considered converters types, and hence, develop more efficient interference-suppression filters (ISF) for switching-type power supplies (STPS) with less development cost. Results are obtained for frequency band of 0-30 MHz.
