Abstract

417,921. Converting. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and RENNER, H. H., c/o General Electric Co., Witton, Birmingham. Jan. 10, 1933, No. 845. [Class 38 (ii).] A change of the moment of ignition in a grid control] ed rectifier to effect regulation is obtained by changing the wave form of the grid voltage. The grid voltage comprises a component of fundamental frequency obtained from a transformer 6 on which is superimposed a third harmonic voltage obtained from a potentiometer 10 supplied from the open-delta secondary of a three phase transformer 13. The magnitude and phase-position of this harmonic can be varied by adjusting the tapping 11 on the potentiometer.
