Abstract: 664,021. Control systems for consumption apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 11, 1949 [Oct. 26, 1948], No. 26084/49. Class 38 (iv). Inductive control.-In a system comprising a pair of series-connected saturable reactors 8, 9 for regulating the load voltage by altering the relative impedance values of the reactors, the core saturation is also arranged to vary as a function of the load current, without changing the relative impedance values of the reactors, so as to prevent desaturation of the cores at high load current and avoid excessive circulating currents at low load current values. In the system shown one circuit 18 feeds seriesconnected saturating coils 19, 20 for fixing the secondary output voltage and another circuit 21 feeding series-connected saturating coils 22, 23 for varying the saturation of the reactor cores according to load current and arranged such that the two saturating windings on one core boost and on the other core buck. Current for circuit 18 is supplied from circuit 21 over two  potentiometers 26, 27 which permits variation of the magnitude and direction of the control current. Circuit 21 is fed from the series-connected rectifiers 24, 25 energized respectively from a constant source 29 and the load current through transformer 30, the source 29 establishing a constant component of saturating current. Preferably the saturating coils are arranged such that when the potential of line 12 is to be made as near as possible to tapping 6 on transformer 35 (which may be auto-wound), core 16 is saturated by the boosting coils 19, 22 and core 17 is unsaturated by the bucking coils 20, 23. Similarly when line 12 is made as near to the potential of tapping 7. Core 16 is unsaturated and core 17 is saturated. The two reactors may also function as an auto-transformer, Fig. 3 (not shown), by providing two pairs of A.C. windings on each core, one winding on each core being series-connected across the supply and the other winding on each core being series-connected in the load-circuit, the windings included in the load circuit respectively bucking and boosting the line voltage.
