Broadband modeling of magnetic components with saturation and hysteresis for circuit simulations of power converters

A model of magnetic components is presented which includes saturation and static hysteresis and covers a wide frequency range. A dedicated setup measures the B(H)-curves for extraction of the model parameters and for model validation. The magnetic model is then described in terms of a spice circuit and used in transient system simulations of power converters. Simulations and measurements of core losses, and filter performance of common mode chokes are discussed.
