Abstract
본 발명은 초기 전원인가시나 모드 변환시 또는 과도한 B+전압 인가시 회로의 이상조건으로 인해 고압이 증가하여 발생되는 엑스레이를 차단할 수 있도록 하는 모니터의 엑스레이 차단회로에 관한 것으로, 고압을 발생시키는 플라이백 트랜스부와, 상기 플래이백 트랜스부에 접속되며 인가된 전압을 다운시켜 정류시키는 정류부와, 상기 정류부에 접속되며 정류부로부터 입력된 전압과 기준전압을 비교하여 증폭시키는 비교증폭부와, 상기 비교증폭부에 접속되며 비교증폭부로부터 인가된 신호에 따라 온.오프되는 스위칭부와, 상기 스위칭부에 접속되며 스위칭부의 동작상태에 따라 동작이 제어되는 수평발진회로부로 이루어진 것이다.The present invention relates to an X-ray blocking circuit of a monitor that can block X-rays generated by an increase in high voltage due to an abnormal condition of a circuit during initial power-up, mode conversion, or excessive B + voltage. And a rectifying part connected to the flyback transformer part to lower the applied voltage to rectify the comparator, a comparison amplifier part connected to the rectifying part to compare and amplify a voltage input from the rectifying part, and a comparative amplifier part; A switching unit is connected and turned on or off in accordance with a signal applied from the comparison amplifier, and a horizontal oscillation circuit unit connected to the switching unit and the operation is controlled in accordance with the operating state of the switching unit.
