Transistor converter with self starting circuit

Claim 1

IN A POWER SUPPLY SYSTEM, A TRANSFORMER HAVING A SATURABLE CORE WITH FIRST, SECOND AND THIRD WINDINGS WOUND THEREON, SAID FIRST WINDING HAVING FIRST AND SECOND END TERMINALS AND THIRD, FOURTH, AND FIFTH TERMINALS INTERMEDIATE TO SAID FIRST AND SECOND END TERMINALS, SAID SECOND AND THIRD WINDINGS EACH HAVING FIRST AND SECOND END TERMINALS AND A THIRD TERMINAL INTERMEDIATE TO SAID FIRST AND SECOND END TERMINALS, A SOURCE OF INPUT POTENTIAL HAVING FIRST AND SECOND TERMINALS, FIRST, SECOND, THIRD, AND FOURTH TRANSISTORS EACH HAVING BASE, COLLECTOR AND EMITTER ELECTRODES, SAID FIRST AND SECOND TRANSISTORS CAPABLE OF PASSING LARGE CURRENTS, SAID THIRD AND FOURTH TRANSISTORS CAPABLE OF PASSING ONLY SMALL CURRENTS, MEANS FOR CONNECTING THE EMITTER ELECTRODES OF SAID FIRST AND FOURTH TRANSISTORS TO SAID FIRST TERMINAL OF SAID SOURCE OF INPUT POTENTIAL, MEANS FOR CONNECTING THE COLLECTOR ELECTRODES OF SAID SECOND AND THIRD TRANSISTORS TO SAID SECOND TERMINAL OF SAID SOURCE OF INPUT POTENTIAL, MEANS FOR CONNECTING THE COLLECTOR ELECTRODE OF SAID FIRST TRANSISTOR TO THE FIRST END TERMINAL OF SAID FIRST WINDING, MEANS FOR CONNECTING THE EMITTER ELECTRODE OF SAID SECOND TRANSISTOR TO THE SECOND END TERMINAL OF SAID FIRST WINDING, MEANS FOR CONNECTING THE EMITTER ELECTRODE OF SAID THIRD TRANSISTOR TO THE THIRD INTERMEDIATE TERMINAL OF SAID FIRST WINDING, MEANS FOR CONNECTING THE COLLECTOR ELECTRODE OF SAID FOURTH TRANSISTOR TO THE FOURTH INTERMEDIATE TERMINAL OF SAID FIRST WINDING, MEANS FOR CONNECTING THE BASE ELECTRODE OF SAID FOURTH TRANSISTOR TO THE FIRST END TERMINAL OF SAID SECOND WINDING, MEANS FOR CONNECTING THE BASE ELECTRODE OF SAID FIRST TRANTRANSISTOR TO THE FIRST END TERMINAL OF SAID SECOND WINDING MEANS FOR CONNECTING THE BASE ELECTRODE OF SAID FIRST TRANSISTOR TO THE SECOND END TERMINAL OF SAID SECOND WINDING, MEANS FOR CONNECTING THE BASE ELECTRODE OF SAID SECOND TRANSISTOR TO THE FIRST END TERMINAL OF SAID THIRD WINDING, MEANS FOR CONNECTING THE BASE ELECTRODE OF SAID THIRD MEANS FOR CONNECTING THE BASE ELECTRODE OF SAID THIRD TRANSISTOR TO THE SECOND END TERMINAL OF SAID THIRD WINDING, MEANS FOR CONNECTING THE THIRD INTERMEDIATE TERMINALS OF BOTH SAID SECOND AND THIRD WINDINGS TO THE FIRST TERMINAL OF SAID SOURCE OF INPUT POTENTIAL, MEANS FOR CONNECTING THE FIFTH INTERMEDIATE TERMINAL OF SAID FIRST WINDING TO THE SECOND TERMINAL OF SAID SOURCE OF INPUT POTENTIAL, AND MEANS FOR CONNECTING THE THIRD INTERMEDIATE TERMINAL OF SAID THIRD WINDING TO THE FIFTH INTERMEDIATE TERMINAL OF SAID FIRST WINDING WHEREBY SAID FIRST AND SECOND TRANSISTORS ARE RENDERED SIMULTANEOUSLY CONDUCTIVE DURING INTERMEDIATE PERIODS AND SAID THIRD AND FOURTH TRANSISTORS ARE RENDERED CONDUCTIVE DURING INTERVALS SEPARATING SAID PERIODS.
