Abstract :
This paper presents a hysteresis model for hard magnetic core materials which is based on the theory of ferromagnetic hysteresis. Furthermore, an easy technique is demonstrated for calculation of the model parameters from measured data. The mathematical model exhibits all the main features of hysteresis and consists of only nine parameters. Additionally, this model can be realized by a macromodel which is completely compatible with the well-known circuit simulator SPICE2
