The Preisach model can be used for detailed analysis of devices based on ferromagnetic materials, if its parameter, its weighting function, is well-known. Usually the weighting function is approximated by analytical formula. The second approach is to

Many applications of the Preisach model need a lot of repeated calculations. Therefore, the algorithm speed is an important program parameter. Two ways of calculation acceleration are considered: improvement of the algorithm and reduction of the Prei

Determination of the weighting function of the Preisach hysteresis model depends strongly on the quality of experimental data. The paper focuses on errors in the input excitation current. The analysis of experimental data and their processing were id

The practical use of Preisach hysteresis model is based on proper identification of weighting function that characterizes the material. Obtaining of the weighting function needs two partial derivations of two-dimensional flux density function, called

Identification of Preisach model supposes a perfect experiment. One condition is that prescribed harmonic current without any errors flows in the toroid primary winding. The condition can be ensured by a suitable filter that was designed after the co

The Preisach model weighting function is given by partial derivations of a measured magnetic flux density that leads to high errors. Therefore other methods of the weighing function estimation are used frequently. In order to verify the direct approa

Usually analytical weighting function is used in Preisach model application, since the use of derivation of experimental first order reverse curves exhibits large errors. To reduce the errors, extended experiments and methods for reduction of experim
