Abstract

본 발명은 모니터의 고전압 안정화 회로에 관한 것으로, FBT로부터 감지된 궤환전압에 따라 벅컨버터가 DC 입력을 PWM 제어하여 상기 FBT 로 인가되는 B+전압을 제어하고, 이에 따라 수상관의 애노드에 인가하기 위한 고전압을 안정화시키도록 된 모니터의 고전압회로에 있어서, 상기 FBT로부터 ABL 전류의 변동을 검출하여 소정 크기로 증폭하는 버퍼(20); 및 상기 버퍼의 출력을 상기 벅컨버터의 입력으로 전달하기 위한 궤환전압 전달부(22)으로 구성되어 모니터 수상관에 애노드에 인가되는 고전압의 변동에 민감하게 반응하여 고전압을 안정화시키는 효과가 있디.The present invention relates to a high-voltage stabilization circuit for a monitor, in which a buck converter PWM-controls a DC input according to a feedback voltage sensed from an FBT to control a B + voltage applied to the FBT, A buffer (20) for detecting a variation of the ABL current from the FBT and amplifying the ABL current to a predetermined magnitude; And a feedback voltage transfer unit 22 for transferring the output of the buffer to the input of the buck converter so as to stabilize the high voltage by sensitively reacting to the fluctuation of the high voltage applied to the anode.
