A hysteresis model for magnetic materials using the Giles-Atherton model

The problem of determining parameters of the Giles-Atherton model used for defining hysteresis curves of magnetic materials was analyzed. Results obtained by numerical simulation of hysteresis curves of the ferromagnetic, hard magnetic core and anisotropic materials have been given. The hysteresis curve obtained is in good agreement with the curve defined for these materials in the PSpice program packet. The proposed method for parameter determination enables simulation of any magnetic material, which has a characteristic R, Z or F-shaped hysteresis curve.
