Claim 1

IN COMBINATION, A MULTI-PHASE SOURCE OF ALTERNATING CURRENT, A LOAD CIRCUIT HAVING FIRST AND SECOND TERMINALS, MEANS FOR RECTIFYING SIGNALS FROM SAID SOURCE AND APPLYING DIRECT CURRENT POWER TO SAID LOAD CIRCUIT COMPRISING, FIRST AND SECOND CONDUCTION PATHS FOR EACH PHASE OF SAID SOURCE BOTH CONNECTED AT ONE END TO SAID SOURCE AND RESPECTIVELY CONNECTED AT ONE END TO THE FIRST AND SECOND TERMINALS OF SAID LOAD CIRCUIT, AT LEAST THE FIRST OF THE CONDUCTION PATHS FOR EACH PHASE INCLUDING A CONTROLED RECTIFIER CONNECTED IN SERIES WITH SAID LOAD CIRCUIT, MEANS FOR CONTROLLING THE CONDUCTION TIME OF SAID CONTROLLED RECTIFIERS INCLUDING A CIRCUIT FOR EACH PHASE OF SAID SOURCE FOR PRODUCING TRIGGER PULSES IN SYNCHRONISM WITH THE ALTERNATING SIGNAL OF THE RESPECTIVE PHASE, A DELAY CIRCUIT, MEANS COUPLING THE TRIGGER PULSES FROM ALL PHASES TO SAID DELAY CIRCUIT TO DERIVE A TRAIN OF PULSES SEPARATED FROM EACH OTHER BY THE PHASE ANGLE BETWEEN THE ALTERNATING SIGNALS FROM SAID SOURCE AND EACH DELAY A PREDETERMINED AMOUNT FROM ITS CORRESPONDING TRIGGER PULSE, MEANS FOR APPLYING SAID DELAYED PULSES IN PARALLEL TO ALL OF SAID CONTROLLED RECTIFIERS, AND MEANS FOR CONTROLLING THE DELAY TIME OF SAID DELAY CIRCUIT.
