Abstract
A control circuit comprises two series-connected pairs of saturable reactors, the two pairs being connected in parallel between a supply line and a load. Between one pair of reactors are connected two back-to-back diodes, the center tap of which is connected to the common point of the other pair of reactors. The difference between the voltages across the reactor main windings causes feedback which increases the magnetization of the cores and reduces further the impedance of the low impedance windings.
