Description
Summary:This paper deals with circuit models that can be used to represent printed circuit lands of switched-mode power supplies (SMPS). These circuit models are useful for the prediction of the electromagnetic emissions radiated from such converters. Representations of SMPS built on printed circuit board (PCB) in terms of lumped circuits and lumped-circuit iterative structures are considered and compared under different SMPS load conditions. These circuit models are also validated against measurements.
