G05F 1/33 with plural windings through which current to be controlled is conducted
Full Title
Automatic systems in which deviations of an electric quantity from one or more predetermined values are detected at the output of the system and fed back to a device within the system to restore the detected quantity to its predetermined value or values, i.e. retroactive systems > Regulating voltage or current (G05F1/02 takes precedence) > wherein the variable actually regulated by the final control device is AC (G05F1/625 takes precedence) > using magnetic devices having a controllable degree of saturation as final control devices > with plural windings through which current to be controlled is conducted
