Parallelogram Shaped Hysteresis Loops for Describing the Energetic Magnetic Behavior of Hysteretic Media
No full textThe characterization of the energetic magnetic behavior
of hysteretic materials and the determination of the surface
impedances are proposed. A numerical model in time domain is
adopted for the calculations. The use of parallelogram-shaped hysteresis
loops allows for simplifying the numerical formulation and
for reducing the computation time with respect to more accurate
models. Equivalent major loops have been defined starting from
the measured ones. Comparison with the modified scalar Preisach
model is presented and discussed

No full textThis paper deals with the characterization of dynamic loops shapes and losses in soft magnetic materials. An experimental and theoretical
analysis has been done in order to describe static and dynamic hysteresis on soft ferrite cores. A parallelogram-loop-based
hysteresis modeling is described and discussed. The possibility of the model to include vector hysteresis and the related properties are
then discussed, with particular attention to the case of a rotating magnetic field into an isotropic and anisotropic medium
