Abstract

A new method of SPICE macromodeling of magnetic components is proposed. It is based on an electric equivalent circuit of electromagnetic laws, where magnetic field intensity and magnetic flux density are simulated with corresponding voltages. The B-H anhysteretic nonlinear curve is piecewise-linear approximated with a “table defined” controlled source, and the hysteresis is introduced with a Schmidt trigger circuit. Using the analog behavioral modeling facilities of modern SPICE type simulators, an accurate and a highly computationally efficient macromodel was developed
