Model for Simulation of Nonlinear Inductors in Virtual Environments

Abstract

The digitalization of the contemporary education strongly depends on the development of virtual and remote laboratories. Before a virtual copy of a real lab is created, it should be modelled in accordance with the requirements of the virtual environment. In this study is created a simple and accurate model of a nonlinear inductor, based on voltagecontrolled nonlinear current sources. Their amplitudes and phase-shifts are approximated with a linear model as a function of the supplied sinusoidal voltage amplitude. The model showed very high accuracy with coefficients of determination above 0.98 for the amplitudes and above 0.93 for the phase shifts.
