IN AN A.C. VOLTAGE REGULATOR, THE COMBINATION INCLUDING LOAD MEANS, AN A.C. SOURCE AT LEAST TWO A.C. MAGNETIC CIRCUITS, EACH OF SAID M AGNETIC CIRCUITS HAVING AN A.C. MAIN WINDING AND AT LEAST ONE OF SAID CIRCUITS HAVING AN AUXILIARY WINDING CONNECTED IN SERIES WITH ITS MAIN WINDING, AT LEAST ONE OF SAID MAGNETIC CIRCUITS HAVING D.C. SATURATING MEANS, SAID MAIN WINDING MEANS BEING CONNECTED SERIALLY, MEANS CONNECTING SAID A. C. SOURCE ACROSS SAID SERIALLY CONNECTED MAIN WINDING MEANS, MEANS CONNECTED SAID AUXILIARY WINDING MEANS TO SAID LOAD MEANS AND THE OTHER SIDE OF THE LOAD TO SAID OTHER MAIN WINDINGS MEANS, AT LEAST ONE OF SAID MAGNETIC CIRCUITS HAVING AN AIR GAP LOCATED IN A PORTION THEREOF TO AFFECT ONLY A.C. FLUX PRODUCED BY THE MAIN WINDING, SAID AIR GAP SERVING TO REDUCE THE CYCLING VARIATION OF THE RELUCTANCE OF THE CIRCUIT IN WHICH IT IS LOCATED, AND MEANS FOR APPLYING D.C. TO SAID SATURATING MEANS.
