Static inverter

Claim 1

IN A POLYPHASE STATIC INVERTER FOR CONVERTING DIRECT CURRENT VOLTAGE RECEIVED OVER AN INPUT CIRCUIT INTO THREE PHALE ALTERNATING CURRENT VOLTAGE, THE COMBINATION OF THREE PAIR OF CONTROLLED RECTIFIER CIRCUITS; MEANS FOR APPLYING A DIRECT CURRENT VOLTAGE TO SAID RECTIFIER CIRCUITS TO ENERGIZE THE SAME; SIX MAGNETIC SHIFT REGISTERS COUPLED TO SAID RECTIFIERS IN A PREDETERMINED MANNER; A TIMING PULSE GENERATOR CIRCUIT COUPLED TO SAID SHIFT REGISTERS TO EFFECT OPERATION THEREOF, EACH OF SAID SHIFT REGISTERS COMPRISING A MAGNETIC CORE, AN INPUT WINDING FOR MAGNETIZING SAID CORE, AN OUTPUT WINDING FOR DETECTING A CHANGE IN THE DIRECTION OF MAGNETIZATION OF SAID CORE AND COUPLED BOTH TO ONE OF SAID RECTIFIER CIRCUITS TO AN INPUT WINDING OF A SUCCEEDING SHIFT REGISTER, A RESET WINDING FOR COUPLING TO SAID INPUT CIRCUIT FOR ESTABLISHING THE INITIAL DIRECTION OF MAGNETIZATION OF EACH OF SAID CORES, AND A SHIFT WINDING COUPLED TO SAID TIMING PULSE GENERATOR CIRCUIT FOR SHIFTING THE DIRECTION MAGNETIZATION OF SAID CORE THEREBY CONTROLLING THE CONDUCTION OF ONE OF SAID RECTIFIER CIRCUITS.
