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 wherein the variable actually regulated by the final control device is ac using bucking or boosting transformers as final control devices combined with discharge tubes or semiconductor devices semiconductor devices only
