Abstract :
In this paper, a modified Jiles-Atherton model within APLAC is introduced. This model can be used to to simulate inductors and transformers in a switch-mode power supply at large signal input. An optimization method is coupled to an iterative algorithm to identify the Jiles-Atherton parameters for a modified Jiles-Atherton model. The verification of the modified model is done by comparing simulated hysteresis loops to experimental results at different frequencies. The results state that the modified model is valid.
