1929 General Electr. Rev. Apr. 213/1 The thyratron is an electrically controlled arc rectifier.
1948 Jrnl. Royal Aeronaut. Soc. 52 216/1 An automatic speed control has been provided in which the voltage from a tachometer generator driven by the fan shaft is composed with a pre~set standard voltage, and the difference amplified by thyratrons is fed back to an auxiliary field in the generator.
1981 J. Seymour Electronic Devices & Components iv. 185 Industrial process control, the control of electrical machines and high voltage d.c. transmission are among the many areas in which thyristors are applied. They have superseded the thyratron..in all but the highest voltage applications.
