MANUFACTURE OF X-RAY TUBE AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an X-ray tube manufacture device capable of suppressing an exciting rush current securely at low cost without using a special circuit and a special sensor. SOLUTION: A bidirectional semiconductor switching element 17 is turned on at a timing of generating positive polarity output when applying a high voltage to a high voltage transforming device 18 between a positive electrode 12 and a negative electrode 13 of the X-ray tube 11. And a bidirectional semiconductor switching element 17 is turned off at a timing of generating a negative polarity opposite to the positive polarity. Initial magnetic flux of an opposite direction to remanent magnetic flux of a core is necessarily generated in making. An exciting inrush current can be securely suppressed without a special circuit and a special sensor.
