System Regularity in Parallel Ferroresonant Chaotic Circuit Derived from Chua Type Magnetization Model

To consider regularity of chaotic behaviors in the up-to-date power devices, this paper shows time-varying poles of a parallel ferroresonant circuit containing a hysteretic magnetic material. Applying Chua-type magnetization model to the magnetic element performs transient analysis by means of state equations. The time-varying poles obtained from state transition matrices in each of calculation steps reveal that the chaotic behavior in the ferroresonant circuit is greatly concerned with the magnetic aftereffect of ferromagnetic materials.
