Nonlinear Modeling of Magnetic Inductor with Hysteresis in Pspice

摘要

A nonlinear modeling of magnetic inductor with hysteresis using PSpice is presented. The describing functions are used to model the high frequency hysteresis to make up the defect of Jile-Atherton static hysteresis mathematical model. The subcircuits which include the nonlinear magnetic inductor are used to the circuit of filter by PSpice. The hysteresis-related characteristic of intermodulation distortion and corner frequency can be predicted by the improved inductor subcircuit models have been verified experimentally.
