Convergence of harmonic series of direct and inverse approximation of the magnetization curve.

Abstract

The formulas for calculating the harmonic series of direct and inverse approximations of the magnetization curve of a broken line, described by nonlinear equations, are given. The example of the magnetization curves of the ferrites HH-1000 and NM-2000 considers the convergence of the induction series and the magnetic field strength under the condition of sinusoidal variable variable. that the magnetization curve with a high degree of nonlinearity requires more harmonic terms to describe the magnetization curve with a sufficient degree accuracy.
