Abstract
A power supply device for an X-ray tube includes first and second capacitors connected in series at one ends thereof which are connected with a secondary winding of a high-tension transformer. Connectedly arranged between a positive output terminal and the ground are first and second diodes which are connected in series to assume the same polarity, each having a cathode as a positive output side, a connecting point of the first and second diodes being connected with the other end of the first capacitor. Also connectedly arranged between a negative output terminal and the ground are third and fourth diodes which are connected in series to assume the same polarity, each having an anode as a negative output side, a connecting point of said third and fourth diodes being connected with the other end of the second capacitor. First and second high-tension cables include a covering conductor connected with the ground, respectively. The first high-tension cable is connectedly arranged between the positive output terminal and an anode of the X-ray tube, whereas the second high-tension cable is connectedly arranged between the negative output terminal and a cathode of the X-ray tube.
