Transistor core converter with current feedback

Claim 1

A CONVERTER CIRCUIT COMPRISING FIRST AND SECOND TRANSISTORS EACH HAVING BASE, COLLECTOR, AND EMITTER ELECTRODES, A SOURCE OF INPUT POTENTIAL, A LOAD, A TRANSFORMER HAVING PRIMARY AND SECONDARY WINDINGS, SAID PRIMARY AND SECONDARY WINDINGS EACH HAVING AT LEAST FIRST AND SECOND PORTIONS, MEANS SERIALLY CONNECTING THE EMITTERCOLLECTOR PATH OF SAID FIRST TRANSISTOR WITH SAID FIRST PORTION OF SAID PRIMARY WINDING AND SAID SOURCE OF INPUT POTENTIAL, MEANS SERIALLY CONNECTING THE EMITTER-COLLECTOR PATH OF SAID SECOND TRANSISTOR WITH SAID SECOND PORTION OF SAID PRIMARY WINDING AND SAID SOURCE OF INPUT POTENTIAL, A FIRST SUBSTANTIALLY IMPEDANCE FREE LOAD CURRENT FEEDBACK PATH SERIALLY CONNECTING SAID LOAD, THE EMITTERBASE PATH OF SAID FIRST TRANSISTOR, AND SAID FIRST PORTION OF SAID SECONDARY WINDING, AND A SECOND SUBSTANTIALLY IMPEDANCE FREE LOAD CURRENT FEEDBACK PATH SERIALLY CONNECTING SAID LOAD, THE EMITTER-BASE PATH OF SAID SECOND TRANSISTOR, AND SAID SECOND PORTION OF SAID SECONDARY WINDING, WHEREBY A LOAD CURRENT FEEDBACK PATH IS PROVIDED FOR SAID FIRST AND SECOND TRANSISTORS AND THE SWITCHING TIME OF SAID FIRST AND SECOND TRANSISTORS IS REDUCED.
