Abstract

A series-LCR circuit is one of the simplest circuits capable of exhibiting ferroresonance. A numerical simulation of such a circuit is constructed using the Preisach model of hysteresis to accurately represent the non-linear magnetic response of the inductor. Numerical data obtained from this simulation shows good agreement when compared to data from a laboratory-built experimental circuit. A bifurcation diagram is constructed to illustrate the coexistence of multiple solutions and the existence of period doubling.
