Abstract :
Frequency-selective transmission line (TL) EMI filter can be used to attenuate the high frequency (HF) noise in power electronics systems. In order to understand the attenuation mechanism and to facilitate the design of the TL EMI filter, analysis of the differential mode (DM) TL EMI filter is given in this paper based on multi-conductor lossy transmission line model and finite element simulation using Ansoft 2D Extractor. The dependences of filter performance on dimensions and material properties are shown. Relative permittivity and thickness of the dielectric layer, conductivity and relative permeability of nickel layer are the dominating influencing factors on the filter performance.
