摘要:
This paper describes an experimental investigation of the dependence of the space-charge smoothing factor on valve geometry. It is found that ifAis expressed as a function of the ratio between barrier-to-anode potential and mean emission energy (expressed in volts),Ais independent of valve geometry.The results are compared with several hypotheses and the discrepancies noted. The various hypotheses, and the relations between them, are discussed in some detail.A spurious effect, of unknown origin, appears to enter whenA≃ 0.1, and further experiments are suggested.

摘要:
The paper is divided into three main sections. The first of these deals with the method of manufacture and formation of the discs, and with the forward and reverse voltage/current and voltage/resistance characteristics and the effects of temperature variations, ageing and capacitance. This section includes a brief account of a theory of the operation of the rectifier.The second section describes the design of actual rectifiers for resistive or inductive loads and also a new method of design for battery-charging rectifiers, the mathematical theory of which is given in an appendix. A new method of construction is described which enables the output of a rectifier to be increased.In the final section, a description is given of some of the applications of the rectifier, including the use of oil-cooling for large outputs.
