Claims (1)

  1. 4개의 스위칭 소자를 부리지 접속하고, 적어도 2개의 스위칭소자를 고주파 초퍼로 하여 동작시키고, 고압트랜스의 2차측에서 고압출력을 얻는 부리지 인버어터와, 상기 고압 출력이 인가되는 X선관을 구비한 부리지 인버어터형식의 X선장치에 있어서 상기 X선관의 양극전압을 검출하여, 이 검출출력이 소정치가 되는 제어신호를 상기 초퍼에 공급하는 피이드백제어수단을 설치하는 동시에, 상기 고압트랜스의 1차측 권선의 축적에너지를 방출하는 경로내에 저항을 삽입접속한 것을 특징으로 하는 X선장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
