This paper discusses the inductor-saturation-aware design of switching power supply. A new modeling and analysis method is presented, including thermal dependence of parameters, which allows a reliable prediction of current wave-shape and consequent losses for Ferrite Core (FC) inductors. The proposed algorithm can be easily applied to predict the range of the operating conditions sustainable for FC inductors, including saturation. The proposed method is best suited for the identification of optimal high-power-density power supply design solutions.

Abstract
This paper discusses the inductor-saturation-aware design of switching power supply. A new modeling and analysis method is presented, including thermal dependence of parameters, which allows a reliable prediction of current wave-shape and consequent losses for Ferrite Core (FC) inductors. The proposed algorithm can be easily applied to predict the range of the operating conditions sustainable for FC inductors, including saturation. The proposed method is best suited for the identification of optimal high-power-density power supply design solutions.File in questo prodotto:
