The Jiles-Atherton (J-A) model is very suitable for modeling ferrite-core based inductors and transformers. In this paper the differential evolution (DE) method was applied to extract five parameters in static J-A model first. Then it was applied to extract another two parameters in dynamic J-A model with five parameters in static J-A model as inputs. It is found that extracting five parameters in...
In this paper we first introduce the J-A model which is a mathematical model of the hysteresis mechanism in ferromagnets and ferrites. This model is based on the existing ideas of domain wall motion including both bending and translation. Then it is applied to the modeling of a circuit including the nonlinear inductor which displays saturation and hysteresis. Also we construct a module of the nonlinear...
