Transistor voltage regulator for a generator with means for preventing discharge of battery through field winding or output winding

Claim 1

IN COMBINATION, AN ALTERNATING CURRENT GENERATOR HAVING AN OUTPUT WINDING AND A FIELD WINDING, A BRIDGE RECTIFIER NETWORK HAVING OUTPUT TERMINALS CONNECTED WITH SAID OUTPUT WINDING, A TRANSISTOR HAVING EMITTER, BASE AND COLLECTOR ELECTRODES, MEANS CONNECTING THE EMITTER TO COLLECTOR CIRCUIT OF SAID TRANSISTOR BETWEEN ONE OF THE OUTPUT TERMINALS OF SAID BRIDGE RECTIFIER NETWORK AND SAID FIELD WINDING WHEREBY THE FIELD CURRENT THROUGH SAID FIELD WINDING IS CONTROLLED AS A FUNCTION OF THE CONDUCTANCE OF SAID TRANSISTOR BETWEEN EMITTER AND COLLECTOR ELECTRODES, A BATTERY, MEANS CONNECTING SAID BATTERY ACROSS THE OUTPUT TERMINALS OF SAID BRIDGE RECTIFIER NETWORK, MEANS CONNECTING THE EMITTER TO BASE CIRCUIT OF SAID TRANSISTOR ACROSS ONE OF THE RECTIFIERS OF SAID BRIDGE RECTIFIER NETWORK, AND MEANS FOR APPLYING A CONTROL VOLTAGE TO THE BASE ELECTRODE OF SAID TRANSISTOR IN ACCORDANCE WITH THE VOLTAGE APPEARING ACROSS THE OUTPUT TERMINALS OF SAID BRIDGE RECTIFIER NETWORK.
