Converter circuit utilizing primary switching voltage

Claim 1

A POWER SUPPLY SYSTEM FOR PROVIDING D.C. OPERATING POTENTIAL FROM A SOURCE OF D.C. POTENTIAL HAVING A LESSER VALUE, INCLUDING IN COMBINATION, A TRANSFORMER HAVING PRIMARY AND FIRST AND SECOND SECONDARY WINDINGS, A PAIR OF TRANSISTORS HAVING BASE EMITTER AND COLLECTOR ELECTRODES, MEANS FOR CONNECTING SAID EMITTER ELECTRODES TO THE SOURCE OF D.C. POTENTIAL, MEANS CONNECTING SAID COLLECTOR ELECTRODES TO OPPOSITE ENDS OF SAID PRIMARY WINDING, SAID PRIMARY WINDING HAVING A CENTER TAP CONNECTED TO A REFERENCE POTENTIAL, MEANS FOR APPLYING A BIAS POTENTIAL TO SAID PAIR OF TRANSISTORS, SAID FIRST SECONDARY WINDING HAVING A CENTER TAP CONNECTED TO SAID MEANS FOR APPLYING A BIAS POTENTIAL, MEANS CONNECTING SAID BASE ELECTRODES OF SAID TRANSISTORS TO OPPOSITE ENDS OF SAID FIRST SECONDARY WINDING TO PROVIDE SELF-SUSTAINING SWITCHING ACTION ALTERNATELY BIASING SAID TRANSISTORS TO CUT OFF, WHEREBY AN ALTERNATING CURRENT OUTPUT IS APPLIED TO SAID PRIMARY WINDING, A RECTIFIER BRIDGE CIRCUIT INCLUDING A PAIR OF OPPOSITELY POLED DIODE RECTIFIERS CONNECTED TO ONE END OF SAID SECOND SECONDARY WINDING, A SECOND PAIR OF OPPOSITELY POLED DIODE RECTIFIERS CONNECTED TO THE OPPOSITE END OF SAID SECOND SECONDARY WINDING, OUTPUT FILTER MEANS CONNECTED TO ONE RECTIFIER CONNECTED TO EACH END OF SAID SECOND SECONDARY WINDING TO PROVIDE A FILTERED D.C. OUTPUT, MEANS CONNECTING THE OTHER RECTIFIER CONNECTED TO EACH END OF SAID SECONDARY WINDING TO THE ENDS OF SAID PRIMARY WINDINGS RESPECTIVELY, WHEREBY THE VOLTAGE ACROSS THE OPERATIVE PORTION OF SAID PRIMARY WINDING IS ADDED TO THE VOLTAGE ACROSS SAID SECOND SECONDARY WINDING AT SAID CONDUCTOR MEANS, TO PROVIDE A RECTIFIED D.C. OUTPUT POTENTIAL WHICH IS SUBSTANTIALLY INCREASED OVER THE POTENTIAL RESULTING FROM THE VOLTAGE IN SAID SECOND SECONDARY WINDING.
