Exact Simulation of Conducted EMI in Switched Mode Power Supplies 1999-01-2598

Exact simulation of conducted EMI in switched mode power supplies is proposed. In order to achieve exact simulations, PSPICE active component ABM model and modified transformer model are proposed. Each model parameter is extracted from measurements and data-books. PSPICE simulation results with high frequency PCB pattern model are accordant with EMI measurements for a 50[W] isolated flyback converter. EMI relations of each component and EMI patterns are analyzed.
