International ClassG05F 001/00AbstractA power regulator system provides power to an electrical load. A power level selector generates a reference signal which indicates a desired power level for the electrical load, and a control circuit connected with a AC power source interrupts flow of the AC current for periods of time responsive to a reference system from the power selector. A filtering circuit filters the output of the control circuit and generates therefrom a second output AC circuit which is smooth relative to this interrupted AC circuit. This smooth AC output is applied to the load. A relay is provided to prevent overload conditions from forming adjacent the load in the circuit. Various types of sensors may be used as the power level indicator, such sensors including the light detector as movement detectors, and other electrical sensors.Field of SearchAutomatic regulationRegulator responsive to plural conditions Variable impedance-type regulator Impedance or current regulator in the supply circuit Periodic switch cut-out Plural periodic switches or multiple contact periodic switch Condenser in shunt to the load device and the supply PULSATING OR A.C.
