NUMERICAL MODELING AND SIMULATION OF HYSTERESIS EFFECTS IN MAGNETIC CORES USING TRANSMISSION-LINE MODELING AND THE PREISACH THEORY

The transmission-line modelling method and the Preisach theory are emp loyed to model and simulate the hysteresis effects of magnetic cores. This combined approach provides a useful method, which allows fast and accurate prediction of magnetic core losses, and simple software impl ementation of the dynamic discrete model. The model can be developed e asily, using data provided by core manufacturers and simple measuremen ts. This paper describes, in a tutorial style, the numerical aspects a nd software implementation of the modelling and simulation of hysteres is for a magnetic core. Step-by-step procedures of the modelling and s imulation are included, and demonstrated in a computer simulation. Bot h simulated and measured results are presented.
