Abstract:
A filter circuit for a linear high voltage power supply configured to provide power to a high power transmitting tube while protecting the tube during a high voltage arc event, said filter circuit comprising:an inductor having a first terminal connected to a first terminal of a rectifier of said linear high voltage power supply and having a second terminal; a capacitor having a first terminal coupled to said second terminal of said inductor, and having a second terminal coupled to a second terminal of said rectifier; and a resistance element comprising a resistor having one terminal coupled to at least one of said inductor and capacitor and having another terminal coupled to said high power transmitting tube, wherein said resistance element is further configured to limit current from at least one of said inductor or capacitor to said high power transmitting tube during the high voltage arc event or other fault condition.
