Modeling Hysteresis Losses in Magnetic Core Inductors for DC–DC

This article proposes the implementation of a method for modeling hysteresis loops and related losses in magnetic core inductors used for power converters applications. The method has been applied to some commercially available ferrite materials in order to verify the accordance of B–H loops and power losses density estimation with acceptable results. Once correctly calibrated, the model could help to characterize magnetic materials hysteresis losses and to optimize the inductor core material choice and dimensioning in high-power density converters design.
