Abstract

313,229. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). March 20, 1928. Transformers. - Electric oscillations are amplified by impressing them on the input circuit of a thermionic valve V, and preventing the direct-current component in the output circuit influencing the secondary winding of an output transformer T2. The primary winding of the output transformer consists of two oppositely connected parts, of which one a is traversed by the anode current and the other b by a direct current only, to compensate the influence of the direct component of the anode current on the secondary winding.
