Claim 1
Independent Claim
151 words
A PUSH-PULL PARALLEL AMPLIFIER INCLUDING CURRENT BALANCING MEANS COMPRISING IN COMBINATION: A PLURALITY OF SIGNAL TRANSLATION DEVICES COUPLED TOGETHER TO FORM A PLURALITY OF PUSH-PULL CIRCUITS CONNECTED IN PARALLEL CIRCUIT RELATIONSHIP; INPUT MEANS FOR COUPLING AN INPUT SIGNAL TO EACH SIDE OF SAID PLURALITY OF PUSH-PULL CIRCUITS; A COMMON LOAD CIRCUIT COUPLED IN SERIES CIRCUIT RELATION WITH EACH SAID PUSH-PULL CIRCUIT; TRANSFORMER MEANS FOR EACH OF SAID PLURALITY OF PUSH-PULL CICUITS, EACH SAID TRANSFORMER MEANS INCLUDING A FIRST, A SECOND, AND THIRD WINDING, SAID FIRST AND SAID SECOND WINDINGS BEING COUPLED TO RESPECTIVE SIDES OF THIS PUSH-PULL CIRCUIT TO BE RESPONSIVE TO THE CURRENT FLOW THEREIN, AND MEANS CONNECTING SAID THIRD WINDING OF EACH SAID TRANSFORMER MEANS IN A SERIES CIRCUIT RELATIONSHIP WITH A PROPER POLARITY SENSE WITH RESPECT TO SAID FIRST AND SAID SECOND WINDING TO GENERATE A FEEDBACK VOLTAGE TO BALANCE THE LOAD CURRENT OF SAID PLURALITY OF DEVICES.
