G05F—SYSTEMS FOR REGULATING ELECTRIC OR MAGNETIC VARIABLES
G05F1/00—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
G05F1/10—Regulating voltage or current
G05F1/12—Regulating voltage or current wherein the variable actually regulated by the final control device is AC
G05F1/32—Regulating voltage or current wherein the variable actually regulated by the final control device is AC using magnetic devices having a controllable degree of saturation as final control devices
G05F1/33—Regulating voltage or current wherein the variable actually regulated by the final control device is AC using magnetic devices having a controllable degree of saturation as final control devices with plural windings through which current to be controlled is conducted
