(EMC). This paper presents a method, called essential :4d7%q  
coupling path models, to investigate the conducted EMI coupling WdnP[x9  
in switching power converters. Three modes of conducted EMI ozG:f*{T  
noise: the mixed-mode (MM), the intrinsic-differential-mode m+ YgfR  
(IDM), and the common-mode (CM) are identified by time domain ]y e&#  
measurements associated with an ac–dc half-bridge converter. ?i"FdpW  
The derived models assume that the lumped parameters’ circuits *WG}K?"/  
represent the noise generation and propagation paths that allow i&KODhMpP  
easy physical interpretations. The experimental results show good Qa+gtGtJ  
agreement by the comparison of measured and predicted MM, 03T.Owd  
IDM, and CM noise emissions with filter included. The proposed
