Abstract
Progress in the design and development of a family of regulated filament supplies utilizing semiconductor electronics throughout is reported. A breadboard representative of a new design technique for the family of filament supplies has been constructed and preliminary tests show the basic design to be capable of meeting the specified requirements. Initial measurements on preliminary breadboards representative of two different design techniques for the 6.3 volt, 20 amp class of regulated filament supplies show that the dissipative method exhibits a !1/3% variation in true rms output voltage and the nondissipative technique exhibits an almost undetectable variation in true rms output voltage over the entire line-load continuum of 105 to 125 v line variation and 2.5 to 20 amp load variation. Design problems which remain are discussed. The work to date in the high voltage supplies consists of the breadboarding of a 1000 v dc regulated supply based on a class C oscillator. The low voltage level of 1000 v was chosen for prototype tests to alleviate the problems of arcing and insulation breakdown during initial circuit feasibility tests. (Author)
