The application of the gaseous discharge tube to problems of voltage regulation
Charles Morton · Journal of Scientific Instruments · 1937
In the use of gaseous discharge tubes as voltage regulators, it has been customary hitherto to restrict the regulated power to that which the discharge gaps are capable of dissipating, and the high cost of tubes of adequate discharge capacity has limited their application in general laboratory work. A method is described whereby inexpensive neon tubes may be used to stabilize relatively large power outputs, and data are given for the design of regulators which deliver direct currents of any desired magnitude and degree of constancy. As an example a description is given of a constant-current supply system which provides regulation within 0.0005 per cent for supply variations of ± 20 per cent.
