Bridge type static inverter network

Claim 1

AN INVERTER COMPRISING A BRIDGE NETWORK HAVING FOUR LEGS AND HAVING FIRST AND SECOND POWER INPUT TERMINALS EACH DEFINING FIRST AND SECOND JUNCTION POINTS BETWEEN A FIRST AND SECOND PAIR OF SAID LEGS, A SOURCE OF DIRECT CURRENT POTENTIAL CONNECTED TO SAID POWER INPUT TERMINALS, A PLURALITY OF CONTROLLED RECTIFIERS EACH HAVING AN ANODE, A CATHODE AND A CONTROL ELECTRODE, MEANS CONNECTING SAID ANODES AND CATHODES OF SAID CONTROLLED RECTIFIERS INTO THE LEGS OF SAID BRIDGE NETWORK, SAID ANODES OF A FIRST PAIR OF SAID CONTROLLED RECTIFIER BEING CONNECTED TO SAID SECOND INPUT TERMINAL, SAID CATHODES OF A SECOND AIR OF SAID CONTROLLED RECTIFIERS BEING CONNECTED TO SAID SECOND INPUT TERMINAL, A FIRST COMMUTATING CAPACITOR CONNECTED BETWEEN THE CATHODES OF SAID FIRST PAIR OF CONTROLLED RECTIFIERS, A SECOND COMMUTATING CAPACITOR CONNECTED BETWEEN THE ANODES OF SAID SECOND PAIR OF CONTROLLED RECTIFIERS, A PAIR OF INDUCTORS EACH SERIALLY CONNECTED BETWEEN THE CATHODES OF SAID FIRST PAIR OF CONTROLLED RECTIFIERS AND THE ANODES OF SAID SECOND PAIR OF CONTROLLED RECTIFIERS TO INTERCONNECT SAID FIRST AND SECOND PAIRS OF SAID LEGS, EACH OF SAID INDUCTORS HAVING AN OUTPUT TERMINAL FOR CONNECTING A LOAD DEVICE THEREBETWEEN, SAID INDUCTORS BEING EFFECTIVE TO ELECTRICALLY ISOLATE THE DISCHARGE CURRENTS OF SAID FIRST AND SECOND COMMUTATING CAPACITORS FROM EACH OTHER, A FIRST PLURALITY OF DIODES EACH CONNECTED ACROSS A RESPECTIVE ANODE AND CATHODE OF ONE OF SAID CONTROLLED RECTIFIERS AND IN OPPOSING CONDUCTIVITY RELATIONSHIP THEREWITH, A SECOND PLURALITY OF DIODES EACH CONNECTED ACROSS A RESPECTIVE ONE OF SAID INDUCTORS IN SERIALLY AIDING CONDUCTIVITY RELATIONSHIP WITH SAID FIRST PLURALITY OF DIODES, AND TRANSFORMER MEANS HAVING OUTPUT WINDINGS CONNECTING SAID CONTROL ELECTRODES TO A SOURCE OF TRIGGERING SIGNALS, SAID TRANSFORMER OUTPUT WINDINGS HAVING A PHASE RELATIONSHIP EFFECTIVE TO SEQUENTIALLY TRIGGER INTO CONDUCTION, SELECTED CONTROLLED RECTIFIERS FROM EACH PAIR OF SAID RECTIFIERS, SAID FIRST AND SECOND PLURALITY OF DIODES BEING OPERATIVE TO PROVIDE A BY-PASS PATH FOR THE FLOW OF TRANSIENT, REACTIVE LOAD CURRENT AROUND SAID CONDUCTING CONTROLLED RECTIFIERS AND AT LEAST A PORTION OF THE WINDINGS OF SAID INDUCTORS WHENEVER SAID SELECTED CONTROLLED RECTIFIERS ARE TRIGGERED INTO A CONDUCTING STATE.
