Magnetic hysteresis modeling and simulation using the Preisach theory and TLM technique

This paper describes the Preisach theory of hysteresis models using a graphical approach. A new simple mathematical function which can relate the Preisach diagrams and the B-H limiting loop is developed and presented. With this new function, the Preisach hysteresis model can be implemented easily without the use of any statistical functions. The model is implemented using the transmission line modeling method and is tested using a practical example. Good agreement is obtained between measurements and simulations.<<ETX>>
