A Novel Method to Predict the Real Operation of Ferrite Inductors With Moderate Saturation in Switching Power Supply Applications
Abstract
This paper presents amethod to predict the real operatio current wave-shape of Ferrite Core (FC) inductors in switching power supply applications involving a moderate inductor saturation.
The method is based on a behavioral analytical model of inductance versus current saturation curve, obtained starting from the data provided by inductors manufacturers. The algorithm developed to solve the nonlinearmodel of the inductor can be applied to predict the range of the operating conditions involving a sustainable partial saturation for FC inductors, and the resulting method is best suited for the selection of minimum size inductors for highpower- density power supply design solutions.
Index Terms—Ferrite Cores, inductors, losses, saturation.
