X-RAY DEVICE COMPRISING POWER SUPPLY PART FOR X-RAY TUBE ELECTRIC POWER SUPPLY

摘要

PROBLEM TO BE SOLVED: To provide an X-ray generator with reduced interference noise and output voltage ripple. SOLUTION: This X-ray generator consists of two sets of the primary and the secondary windings provided in a core of the same transformer. The coupling between the primary windings 16, 26 in the different sets is smaller than that between the primary winding 16 and the secondary winding 31 in the same set. The primary windings of the two sets consist of a power supply which feeds power to an X-ray tube with a high-voltage transformer 3 connected with two inverters 1, 2 which operate at the same frequency. Control of electric power of the secondary side is improved by providing a means to operate the inverters 1, 2 with a duty cycle which is able to be controlled individually at the fixed frequency.
