Abstract

In order to predict the EMI noise of power converters in the design stage, accurately modeling EMI noise source is the first step. This paper presents and analyzes an equivalent modular-terminal-behavioral (MTB) EMI noise source model. The equivalent MTB EMI noise source is compared with other EMI noise source model. The equivalent MTB noise source and impedance are used to accurately predict the EMI noise for a chopper circuit. The modeling methodology is verified by simulation and experiment. This approach can be applied to model different devices switching EMI behavior
