Push-pull parallel operating circuit for power transmission devices

Claim 1

PARALLEL OPERATION OF POWER ELECTRON EMISSION MEANS COMPRISING: AT LEAST TWO PAIRS OF ELECTRON EMISSION DEVICES, EACH ELECTRON EMISSION DEVICE HAVING A PAIR OF CONDUCTION ELECTRODES AND A CONTROL ELECTRODE FOR CONTROLLING CURRENT CONDUCTION IN THE CONDUCTION ELECTRODES; AN ALTERNATING CURRENT INPUT OF TWO PHASES, ONE PHASE INPUT BEING COUPLED TO THE CONTROL ELECTRODE OF A FIRST ELECTRON EMISSION DEVICE OF EACH PAIR AND THE OTHER PHASE INPUT BEING COUPLED TO THE CONTROL ELECTRODE OF A SECOND ELECTRON EMISSION DEVICE EACH PAIR; AND A PAIR OF OUTPUT TRANSFORMERS, ONE OF SAID CONDUCTION ELECTRODES OF BOTH OF SAID ELECTRON EMISSION DEVICES BEING IN EACH PAIR OF ELECTRON EMISSION DEVICES BEING COUPLED IN SERIES THROUGH ONE PRIMARY WINDING OF EACH PAIR OF TRANSFORMERS, THE OTHER OF SAID CONDUCTION ELECTRODES OF BOTH OF SAID ELECTRON EMISSION DEVICE PAIRS BEING COUPLED TO ONE TERMINAL OF A VOLTAGE SUPPLY, SAID PRIMARY WINDINGS EACH BEING CENTER TAPPED AND SAID CENTER TAP BEING COUPLED TO THE OTHER TERMINAL OF SAID VOLTAGE SUPPLY PROVIDING PARALDEVICES, AND THE SECONDARY WINDINGS OF SAID PAIR OF OUTPUT TRANSFORMERS BEING COUPLED IN SERIES TO AN OUTPUT CIRCUIT WHEREBY PARALLEL OPERATION OF SAID ELECTRON EMISSION DEVICES ACCOMPLISHES A MINIMUM OF POWER LOSS AND EQUALIZATION OF CURRENTS IN THE ELECTRON EMISSION DEVICES.
