Bridge-type inverter network

Claim 1

IN AN INVERTER NETWORK, A PAIR OF INPUT TERMINALS ADAPTED TO BE ENERGIZED FROM A SOURCE OF UNIDIRECTIONAL POTENTIAL, A PAIR OF OUTPUT TERMINALS, A PLURALITY OF DISCONTINUOUS CONTROL TYPE SEMICONDUCTOR DEVICES, EACH SAID DEVICE HAVING A POWER CIRCUIT AND A CONTROL CIRCUIT AND BEING OF THE TYPE IN WHICH SAID CONTROL CIRCUIT IS NORMALLY INEFFECTIVE TO INTERRUPT CURRENT FLOW THROUGH SAID POWER CIRCUIT, A FIRST AND SECOND ELECTRICAL PATH INTERCONNECTING SAID TERMINALS FOR FLOW OF ENERGY FROM SAID INPUT TO SAID OUTPUT TERMINALS, SAID FIRST PATH INCLUDING AT LEAST A FIRST OF SAID DEVICES, A SECOND OF SAID PATHS INCLUDING AT LEAST A SECOND OF SAID DEVICES, A TIMING NETWORK CONNECTED TO BE ENERGIZED BY A POTENTIAL WHICH IS A FUNCTION OF THE POTENTIAL BETWEEN SAID OUTPUT TERMINALS AND INCLUDING AN ENERGY STORAGE DEVICE AND A PLURALITY OF OUTPUT CIRCUITS, SAID STORAGE DEVICE BEING CHARACTERIZED BY THE FACT THAT IT PREVENTS SUBSTANTIAL CURRENT FLOW THERETHROUGH DURING AN INITIAL TIME INTERVAL UNTIL IT REACHES A PREDETERMINED CHARGE AFTER WHICH IT PERMITS SUBSTANTIAL CURRENT FLOW THERETHROUGH, MEANS INDIVIDUALLY CONNECTING AN INDIVIDUAL ONE OF SAID OUTPUT CIRCUITS TO EACH OF SAID CONTROL CIRCUITS, SAID OUTPUT CIRCUITS BEING SO POLARIZED THAT UPON CHARGING OF SAID STORAGE DEVICE TO SAID PREDETERMINED CHARGE DUE TO CONDUCTION OF SAID FIRST PATH SAID SEMICONDUCTOR DEVICES ASSOCIATED WITH SAID SECOND PATH ARE RENDERED CONDUCTIVE AND SO POLARIZED THAT UPON CHARGING OF SAID STORAGE DEVICE TO SAID PREDETERMINED CHARGE DUE TO CONDUCTION OF SAID SECOND PATH SAID SEMICONDUCTOR DEVICES ASSOCIATED WITH SAID FIRST PATH ARE RENDERED CONDUCTIVE, SAID ENERGY STORAGE DEVICE BEING CHARGEABLE AS A CONSEQUENCE OF ENERGY FLOW THROUGH SAID FIRST PATH, SAID TIMING NETWORK BEING EFFECTIVE AS A CONSEQUENCE OF THE CHARGING OF SAID STORAGE DEVICE TO A PREDETERMINED MAGNITUDE TO ENERGIZE SAID OUTPUT CIRCUITS ASSOCIATED WITH SAID SEMICONDUCTOR DEVICES OF ONE OF SAID PATHS.
