DYNAMIC DAMPING IN AN X-RAY SYSTEM
In an X-ray generator 100 an X-ray tube 102 includes an anode 110 and a cathode 108 and is energized with at least a first high voltage potential. A dynamic damper 120 with a frequency dependent impedance is interposed between the X-ray tube and a source of the high voltage potential. The impedance...

| description | In an X-ray generator 100 an X-ray tube 102 includes an anode 110 and a cathode 108 and is energized with at least a first high voltage potential. A dynamic damper 120 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 120 increases with an increase in frequency associated with tube-spit. The dynamic damper may be a solenoid. In an X-ray generator 100 with resonant switching to provide a first kV level and a second kV level to the X-ray tube 102, the impedance of the dynamic damper 120 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 102. |
