PURPOSE:To easily and safely output steady high voltage by using one of the secondary windings of a transformer as a detecting winding for voltage detection, and stabilizing output voltage by controlling a switching element, and superimposing output of the other secondary windings in the same polarity direction by rectifier circuit. CONSTITUTION:Voltages outputted to the secondary windings 51, 52, -5n-1 of a transformer 3 is also generated in the secondary winding 5n used as a detecting winding in the same condition. Voltage detected by the secondary winding 5n is proportional to voltage supplied to an X-ray tube 2. When switching operation of a switching element 6 is controlled with a switch driving circuit 11 according to detected voltage, each output voltage of the secondary windings 5 (51, 52, -5n) reaches a target value and is stabilized. |
