Abstract
The paper presents a new method for modelling transformer with a hysteresis loop by Jiles-Atherton. The Micro-Cap program allows the modelling of magnetically coupled coils by a description of the parameters of the magnetic circuit connecting the coil and the shape of ferromagnetic hysteresis. The way of determination of parameters describing the shape of the magnetization curve are presented, taking into account the phenomenon of ferromagnetic hysteresis. Simulations were performed by changing the values of induction remanence and coercivity magnetic field and a fixed value of the magnetic field strength, saturation induction, permanent magnetization and the designated voltage. Is an example of the results of numerical calculations.
