Claim 1

A RECTIFIED CURRENT SUPPLY SYSTEM FOR CONTROLLING THE FLOW OF CURRENT FROM A SOURCE OF VARIABLE VOLTAGE TO A LOAD COMPRISING, A SOURCE OF A.C. VOLTAGE, A RECTIFYING CIRCUIT HAVING AN A.C. INPUT CONNECTED TO SAID SOURCE AND D.C. OUTPUT VOLTAGE TERMINALS FOR APPLYING SAID D.C. OUTPUT VOLTAGE TO A LOAD, OUTPUT VOLTAGE CONTROL MEANS CONNECTED BETWEEN SAID A.C. SOURCE AND SAID RECTIFYING CIRCUIT, SAID OUTPUT VOLTAGE CONTROL MEANS INCLUDING A SATURABLE CORE REACTOR HAVING A CONTROL WINIDNG, AND A BIAS WINDING, A SOURCE OF CONSTANT REFERENCE VOLTAGE CONNECTED TO SAID BIAS WINDING AND OPERATIVE TO GENERATE A REFERENCE M.M.F. IN THE CORE OF SAID REACTOR FOR SATURATING SAID REACTOR IN A DIRECTION EFFECTIVE TO INCREASE SAID OUTPUT VOLTAGE, MEANS CONNECTED TO SAID OUTPUT TEMINALS FOR DERIVING A SIGNAL REPRESENTATIVE OF THE LOAD VOLTAGE APPEARING ACROSS SAID TERMINALS, MEANS CONNECTED TO THE OUTPUT OF SAID RECTIFYING CIRCUIT AND OPERATIVE TO DERIVE A SIGNAL REPRESENTATIVE OF THE CURRENT DRAWN BY SAID LOAD, MEANS CONNECTED TO SAID LOAD VOLTAGE SIGNAL DERIVING MEANS AND SAID LOAD CURRENT SIGNAL DERIVING MEANS AND OPERATIVE TO COMPARE SAID SIGNALS WITH EACH OTHER, MEANS CONNECTED TO SAID COMPARING
