Claim 1
Independent Claim
137 words
AN AUTOMATIC VOLTAGE REGULATOR COMPRISING INPUT TERMINALS, OUTPUT TERMINALS, MEANS CONNECTED BETWEEN THE TERMINALS FOR REGULATING THE OUTPUT VOLTAGE BY ADDING TO OR SUBTRACTING FROM THE INPUT VOLTAGE, SENSING MEANS INCLUDING A BRIDGE HAVING A PAIR OF ADJACENT LEGS WHICH HAVE RESISTANCES CONNECTED TO THE OUTPUT TERMINALS FOR SENSING THE DEVIATION OF THE OUTPUT VOLTAGE FROM A PRESELECTED VALUE AND PRODUCING A SIGNAL INDICATIVE OF THE DIRECTION AND MAGNITUDE OF THE DEVIATION, CONTROL MEANS CONNECTED TO RECEIVE THE SIGNAL FROM THE SENSING MEANS AND TO CONTROL THE REGULATING MEANS AND MEANS FOR ALTERING THE VALUE OF THE OUTPUT VOLTAGE FROM WHICH THE SENSING MEANS SENSES THE DEVIATION OF THE OUTPUT VOLTAGE BY ALTERING THE RELATIVE VALUE BETWEEN THE RESISTANCES IN THE PAIR OF ADJACENT LEGS UPON THE REGULATING MEANS ADDING TO OR SUBTRACTING FROM THE INPUT VOLTAGE.
