[EMC]Identification of Essential Coupling Path Models for Conducted EMI Prediction in Switching Power con

Abstract—A knowledge of conducted electromagnetic interference Kq2,J&Ca3  
(EMI) generation and propagation mechanisms can aid TSAVXng  
the engineers working in the field of electromagnetic compatibility x9VR>ux&  
(EMC). This paper presents a method, called essential e-e*%  
coupling path models, to investigate the conducted EMI coupling k\wI^D  
in switching power converters. Three modes of conducted EMI `f+l\'.s  
noise: the mixed-mode (MM), the intrinsic-differential-mode XKepk? E  
(IDM), and the common-mode (CM) are identified by time domain y(0";\V  
measurements associated with an ac–dc half-bridge converter. uj9IK  
The derived models assume that the lumped parameters’ circuits #&ZwQw  
represent the noise generation and propagation paths that allow T_*R^Ukb5
