Abstract: The paper considers the description of DC-biased minor loops with the GRUCAD model. The model is given in the form of a combination of nonlinear and ordinary differential equations, what bears resemblance to the well-known Jiles–Atherton formalism. However the model behaves in a qualitatively different way than the original Jiles’ proposal. The paper points out the differences between both approaches and presents the results of modeling for biased hysteresis loops of a Soft Magnetic Composite core.
