PROBLEM TO BE SOLVED: To provide an X-ray high voltage device and an X-ray CT device which can acquire a highly reliable image by reducing noise.SOLUTION: In an X-ray high voltage device, an HVG 111 supplies a high voltage to an X-ray tube 12. An HVG 112 is connected in series with the HVG 111, and supplies a high voltage to the X-ray tube 12. A high voltage switch 121 switches high voltage supply from the HVG 111 to the X-ray tube 12. A high voltage switch 122 switches high voltage supply from the HVG 112 to the X-ray tube 12. The HVG 111 and HVG 112 stop the output of a high voltage when switching from a state where a high voltage is supplied from the HVG 112 to the X-ray tube 12, to a state where a high voltage is supplied from the HVG 111. |
