Abstract：Multiple-paths paralleled "Source-Coupling Path" frequency domain model was proposed for conducted interference modeling and prediction in power converters.The modeling approach of noise source spectrum and coupling path transfer function was studied.In the proposed model,the spectrum of noise source and transfer function of coupling path were extracted to calculate noise spectrum in frequency domain.The proposed modeling method is simple and not limited to specific circuit structure,which could act as general frequency domain modeling approach for conducted interference modeling and prediction in power converters.Specific sample was used to illustrate the modeling procedure of the multiple paths frequency domain model,which verified its guidance for conducted interference modeling,prediction and suppression in power converters.
