Abstract

PURPOSE: To make it possible to realize a set X-ray tube voltage at a good precision by holding a sample of a peak value of an output signal of a tube voltage detector, and controlling an on-off time rate of a DC/DC converter corresponding to the difference between the output signal and a tube voltage set signal.
CONSTITUTION: A voltage applied to an X-ray tube 8 through a DC/DC converter 3, a high voltage transformer 5, and a rectifier 2 has pulsation by action of switches 4a, 4b of an inverter 4. This tube voltage Vxd having pulsation is detected by a tube voltage detector 9, a peak value Vxp of the detected value is inputted into a sample holder 33, and the peak value Vxp within one wave form of pulsation of the tube voltage is held for a sample synchronizing an off signal of the switches 4a, 4b of the inverter 4. The sample hold value V'xp is compared with a set tube voltage Vset, and an on-off time rate for a DC/DC converter 3 is controlled based on the difference so as to make the tube voltage peak value to be the set value. A set tube voltage can thus be realized at a good precision.
