Abstract : In ferroresonant mode, a transformer is saturated and requires very high currents from the source. Previous studies of ferroresonance could not be performed effectively because of high internal impedance of the source. Introduction of transformers to improve these shortcomings would have also introduced undesirable inductive effects. In this thesis, a transistor voltage source with low internal impedance and high current delivering ability is designed and tested. The source is used to investigate an unsymmetrical mode of series resonance. Resonant circuit behavior is both qualitatively and quantitatively described. (Author)
