Abstract
Modelling the transient simulation of magnetic circuits is the crucial process for development of modern switching mode power converters. Such models are especially important for newly developed magnetic materials, such as amorphous alloys. Paper presents the gyrator-capacitor model of inductive element with core made of high permeability, Co-based amorphous alloy. Parameters of the model were identified during Nedler-Mead method based optimization process. Presented results of modelling confirm that model can be used for SPICE simulations; however, the accuracy of losses modeling is limited in the wide range of frequencies.
