High-speed transistor inverter with switching control transistors

Claim 1

AN INVERTER WHICH COMPRISING A SOURCE OF DIRECT INPUT VOLTAGE, A TRANSFORMER HAVING A PRIMARY WINDING AND A SECONDARY WINDIDNG, A PAIR OF ALTERNATELY CONDUCTING POWER TRANSISTORS EACH HAVING ITS EMITTER-COLLECTOR PATH CONNECTED FROM ONE SIDE OF SIAD SOURCE TO A RESPECTIVELY OPPOSITE END OF SAID PRIMARY WINDING, THE OTHER SIDE OF SAID SOURCE BEING CONNECTED TO AN INTERMEDIATE TAP ON SAID PRIMARY WINDING AND SAID SECONDARY WINDING BEING CONNECTED BETWEEN THE BASE ELECTRODES OF SAID POWER TRANSISTORS, A PAIR OF CONTROL TRANSISTORS EACH HAVING ITS EMITTERCOLLECTOR PATH CONNECTED DIRECTLY ACROSS THE EMITTER-BASE PATH OF A RESPECTIVE ONE OF SAID POWER TRANSISTORS, A POSITIVE FEEDBACK PATH FROM ONE END OF SAID SECONDARY WINDING TO THE BASE ELECTRODE OF ONE OF SAID CONTROL TRANSISTORS, AND A POSITIVE FEEDBACK PATH FROM THE OTHER END OF SAID SECONDARY WINDING TO THE BASE ELECTRODE OF THE OTHER OF SAID CONTROL TRANSISTORS, WHEREBY EACH OF SAID CONTROL TRANSISTORS SWITCHES THE OPPOSITE ONE OD SAID POWER TRANSISTORS TO ITS NON-CONDUCTING STATE AS SOON AS THE OTHER OF SAID POWER TRANSISTORS SWITCHES TO ITS CONDUCTING STATE.
