Operation of Tube Oscillators on a Common Load

This paper presents the problem of obtaining high power by means of a great number of tube oscillators operated in parallel. The principal disadvantages of conventional parallel connection are listed, and the advantages of subdivision of tubes into groups (units) with their tank circuits coupled to a common load circuit are shown. Two principal methods of connecting units, viz., series and parallel, are discussed. Their equivalence both with regard to power and to the possibility of connecting together various power and voltage units is proved. Theoretical analysis is illustrated by experimental data.
