Abstract
In an X-ray generator an X-ray tube includes an anode and a cathode and is energized with at least a first high voltage potential. A dynamic damper with a frequency dependent impedance is interposed between the X-ray tube and a source of the high voltage potential. The impedance of the dynamic damper increases with an increase in frequency associated with tube-spit. In an X-ray generator with resonant switching to provide a first kV level and a second kV level to the X-ray tube, the impedance of the dynamic damper is low at the operational frequency of the resonant switch to promote energy recovery when the resonant switch operates to provide a first kV level to the X-ray tube.
