Abstract :
In this paper an effective means of controlling and regulating voltage with an external-grid rectifier tube is discussed. Four applications of the basic principles are shown, including a low voltage, wide range control, and a primary distribution voltage automatic regulator. Main features are: instantaneous response which enables this regulator to be used in such applications as welding with a pulse of only a few cycles, absence of heavy moving parts as well as absence of contacts for load currents, and low cost.
