Abstract
This paper introduces an efficient method to predict the conducted EMI of switched mode power supply (SMPS) through time domain SPICE simulation, which can be used to design or optimize the filter circuit and quantify the suppression degree of the filter. The SMPS modelling method permits modelling of the SMPS as a noise signal source even when its internal structure is unknown. The method is verified by comparing predicted and measured noise signals.
