Magnetic Hysteresis Modeling and Visualization for Spice Based Environments

Today magnetic materials are employed in a truly wide range of applications, and have contributed materially to advances in electronics. On the other hand computer-based simulation tools are convenient for analyzing complex systems. Unfortunately there is insufficiency of models describing electrical behavior of such nonlinear devises. In order to simulate this devices with modern electronic design automation tools the implementation of SPICE oriented models, is imperative. In presented paper a survey of behavior modeling methods suited for visualization of hysteresis of various magnetic materials is given. In order to reduce the modeling time graphs for fitting the slope of the magnetization curve, histeresis’ area and shape are obtained and present in the paper. The appended simulated results pointed to ability of the presented approach for modeling and visualization of different magnetic histeresises.
