| Summary: | 碩士 === 國立中正大學 === 電機工程所 === 98 === This thesis is to study and analyze conducted electromagnetic interference (EMI) filters for converter applications. The products of switching power supplies are used widely, and in general are with the problems of EMI. The EMI filters are used to suppress conducted EMI and are studied, and then the design of filters and selection of components are presented. An experimental circuit with the topology of flyback converter has been tested, from which measured conducted EMI are used to verity the analysis. Besides, we discuss the inductors constructed with different core materials, and measure their impedance, on which an investigation on the effect of suppressing conducted EMI noise is presented.
