| Abstract |
Both hysteresis and dynamic phenomena must be taken into account in the modeling of magnetic materials. However, in the case of soft ferrites, this is not sufficient. Indeed; temperature is an important parameter because it changes the magnetic characteristics greatly. We are working on a behavioral model aimed at predetermining both the magnetic and electrical characteristics of magnetic components. This model uses the Preisach model in order to generate hysteresis loops. The Preisach model deteriorates for low peak flux density, i.e specifically in the field of application of soft ferrites. Improvements have been brought to it and have allowed us to obtain better predictions of
hysteresis loops. By means an analysis of some magnetic data versus temperature, we have simply introduced the latter in the Preisach model. Results are promising. |
