Claim 1
Independent Claim
167 words
IN AN ELECTRICAL SYSTEM THE COMBINATION INCLUDING, ELECTRICAL GENERATING MEANS HAVING OUTPUT TERMINALS FOR CONNECTION TO A LOAD, LOAD WINDING MEANS FOR SUPPLYING A CURRENT TO THE LOAD, MAIN FIELD WINDING MEANS CONNECTED TO SAID TERMINAL, FOR ESTABLISHING AN ENERGIZING FIELD FOR SAID LOAD WINDING MEANS, AND AUXILIARY WINDING MEANS MOUNTED INDUCTIVELY COUPLED WITH SAID MAIN FIELD WINDING MEANS, A TRANSISTOR HAVING INPUT, COMMON AND OUTPUT ELECTRODES, CIRCUIT MEANS PROVIDING CURRENT VARIATIONS IN DIRECT PROPORTION TO CHANGES IN VOLTAGE OCCURRING ACROSS SAID OUTPUT TERMINALS, MEANS COUPLING SAID INPUT AND COMMON ELECTRODES TO SAID CIRCUIT MEANS SO THAT THE OUTPUT CURRENT OF SAID TRANSISTOR IS VARIED IN DIRECT PROPORTION TO THE OUTPUT VOLTAGE OF SAID GENERATOR, AND MEANS COUPLING SAID TRANSISTOR AND SAID AUXILIARY WINDING MEANS IN SERIES AND ACROSS SAID TERMINALS SO THAT THE TRANSISTOR OUTPUT CURRENT IS FED THROUGH SAID AUXILIARY WINDING MEANS IN A DIRECTION TO GENERATE A FIELD WHICH OPPOSES THE ENERGIZING FIELD TO THEREBY REGULATE THE VOLTAGE APPLIED TO THE GENERATOR OUTPUT TERMINALS.
