Abstract

Two models are proposed to characterize and predict the near electromagnetic field of switched mode power supply (SMPS). One is abstracted from buck converter, which has only one high frequency current loop. The other is from boost converter, which has two high frequency current loops. Analytic representations of the electromagnetic near field for each model are presented. Finally, stabilized simulation results of the near field are given. The models and the simulation methods are of great values to the high-density SMPS´s assembly.
