The Shunt Tube Control of Thyratron Rectifiers

The magnitude control of thyratrons in regulated rectifiers is accomplished effectively by the use of a shunt tube bridged across the d-c output and resistance coupled to the thyratron grids. The shunt tube grid operates from the output of a regulating feedback amplifier to give precision voltage regulation and highly improved dynamic response to transients, as well as electronic ripple suppression. Extensive application of this recent development has been made in supplying plate power to video and d-c amplifiers for radars and computers. Closely regulated d-c power for electronic equipment is not unduly costly when the shunt tube technique is applied.
