G05F 1/565 sensing a condition of the system or its load in addition to means responsive to deviations in the output of the system, e.g. current, voltage, power factor (G05F1/563 takes precedence)
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 DC (G05F1/625 takes precedence) > using semiconductor devices in series with the load as final control devices (G05F1/461 takes precedence) > sensing a condition of the system or its load in addition to means responsive to deviations in the output of the system, e.g. current, voltage, power factor (G05F1/563 takes precedence)
