PSPICE computer modeling of hysteresis effects

Recent versions of PSPICE, a personal computer implementation of the SPICE circuit simulation computer software program, have the capability of simulating the hysteresis loops of magnetic materials. In order to model the hysteresis loop of a particular manufacturer´s magnetic core material, the values of five parameters that affect the shape of the hysteresis loop must be established. A method for illustrating the effect that each parameter has on the shape of the hysteresis loop is presented. The method speeds the process of establishing the parameter values for modeling a particular hysteresis loop
