An Analysis of Abnormal Behavior in Parametric Oscillations

Parametric oscillations occurring in nonlinear magnetic circuits have wide applications in such devices as phase converters, parametric transformers and parametric motors. When such devices are operated under a light loadr the parametric oscillations come into a state of fluctuation or quasi-periodic oscillation, and normal device operation becomes impossible. This paper analyzes the outbreak of such abnormal behavior, and the regions in which the phenomena occur.
