Abstract
This paper describes an integrated active and passive planar electromagnetic-interference (EMI) filter structure with effective noise suppression over a very wide bandwidth. Such hybrid EMI filter paves the way input filter design for future mega-hertz switching power converters. This study shows that it has superior performance over traditional active filters and passive filters. Spectral results of a switching converter from 150kHz to 30MHz using various of active, passive and the proposed hybrid EMI filters have confirmed the validity and high performance of the hybrid EMI filter.
