Abstract
A power supply for an RF transmitting tube while protecting the tube from a high voltage arc event. The supply includes a rectifier circuit configured to be connected to an AC voltage supply and having an output circuit that supplies a DC voltage to a load including the tube and wherein the DC voltage may have a ripple voltage thereon. A control circuit is located intermediate the output circuit and the load for reducing any ripple voltage. The control circuit includes a series solid state switch that is connected in series between the rectifier circuit and the load. The control circuit also includes a reference capacitor coupled to the output circuit and to the load for supplying a reference voltage to the switch so that a voltage at the output circuit that exceeds the reference voltage will be clipped to reduce the voltage that is applied to the load.
