This paper introduces a modeling methodology for the prediction of conducted EMI. The well-known DC-DC buck converter is chosen as illustration example to validate this procedure. A bottom-up approach is proposed to model the entire structure as a collection of individual submodels, which are then connected and simulated using a standard circuit solver. We show how a passive macromodeling procedure can be applied to represent the parasitic effects of all passive elements, including the Printed Circuit Board (PCB) at a reduced computation time.
