Abstract :
This paper deals with conducted emissions in SMPS (Switched Mode Power Supplies). It aims to optimize the size of the input EMI (Electro-Magnetic Interference) filter. A topological method worked out by G.Kron, based on multiphysical and multiscale approach, is used in time and frequency domains. A genetic algorithm is also used to optimize the physical dimensions of the filter. Thus, thanks to waveform estimations and the filter modelling, EMI filtering can be taken into account at the design stage.
