Abstract

646,240. Rectifying; automatic voltage control systems. HIGHAM, E. H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 19, 1948, No. 13558. [Classes 38 (ii) and 38 (iv)] The output of a rectifier comprising one or more discharge valves V1, V2 with .ignition electrodes is controlled by the change in phase of the A.C. supplied to the electrodes by a circuit including a saturable inductance D having a D.C. winding fed from a circuit comprising discharge tubes V5, V6 in which a controlling voltage is compared with another quantity. The variable controlling voltage is derived from a potentiometer N across the D.C. output, and applied to the grid of valve V5 from a potential dividing circuit comprising resistance R1 and valve V4 across an amplifying valve V3. Valve V6, which has a common cathode resistance R2 with V5, is controlled by a steady grid bias derived from resistance R3, and neon tube V7. Windings P, P1 of the saturable inductance D are energized by the D.C. difference of the outputs of valves V5, V6, and the dephased voltage appearing at the junction of resistance R4 and saturable inductance D energized in series from mains transformer T3, is amplified by valve V8 and fed to the rectifier grids through transformer T2. The supply to the grid of V3 may be derived from the output potential so as to maintain this constant.
