Orthogonal-Flux Parametric Voltage Regulator

A mathematical analysis of the orthogonal-flux voltage regulator explains three important properties of the regulator-the output waveform is independent of disturbances in the input waveform, the output voltage shuts off automatically under low line voltage, and the output voltage shuts off automatically under an overload. The output voltage will not tun on again unless the overload is removed and special action is taken to initiate the output. These properties result from parametric action in a ferroresonant circuit.
