Abstract :
The nonlinear dependence on history of magnetic field and magnetization in ferromagnetic materials is described by statistical domain behaviour using phenomenological parameters. These parameters are related to macroscopic hysteresis features (such as coercivity, initial susceptibility, saturation, and remanence), which allows fast and easy identification. Examples of model applications are the prediction of the magnetic behaviour of transformers in DC/DC-converters, inverter fed electrical machines, and magnetoresistive sensors
