Abstract
The paper presents a mathematical model for the hysteresis phenomenon in a multi-winding single-phase core type transformer. In the circuit transformer model, it is assumed that there is a flux common Φ to all windings as nonlinear and hysteretic function of the total currents Θ (Ampere turns) of all windings. To simulate magnetic behaviour of the iron core the feedback scalar Preisach model of hysteresis is developed. The Preisach Distribution Function (PDF) of the iron core material is approximated by functional series including two-dimensional Gauss expressions. Feedback function is represented by the third order polynomial. The hysteresis model has been successfully validated by comparing calculated and measured results of Φ-Θ hysteretic curve.
