Abstract

979,805. Rectifying; automatic regulation. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 5, 1961 [Dec. 8, 1960], No. 43502/61. Heading H2F. [Also in Division G3] A circuit for supplying a load with constant direct voltage comprises an A.C. source, a series resistor 3, a rectifier 4, a capacitor 8 in parallel with the load 9 and a cold cathode tube 5 as shown, so that the alternating voltage is stabilised before rectification. The tube 5 may have an ignition electrode connected to a potentiometer in parallel with the A.C. source.
