Abstract

In this paper, the effects of near field couplings including both magnetic coupling and electric coupling that exist in boost PFC converter are analyzed and modeled. It is obvious that magnetic couplings have more significant effects on conducted DM noise than that of electric couplings. Based on the modeling of boost inductor and capacitor, and estimating both inductive and capacitive couplings using Z parameters or Y parameters obtained by Ansoft HFSS software, the model of near field couplings is set up. This model is verified by comparison of simulated and measured voltage gains
