Abstract

미스컨버젼스 보정장치는 편향요크내에 장착되어 전자빔이 각 화소에 정확하게 주사되지 않는 미스컨버젼스를 보정하기 위한 장치로서, 수직방향으로 화면의 코너부분에 발생한 코너버티컬을 보정하기 위하여 한쌍의 수직편향코일으로부터 인출된 센터탭에 직렬구성한 스위칭용 다이오드가 과열되는 것을 방지하기 위하여 해당열을 소모하는 열저항을 다이오드에 연결구성하였다. 따라서, 스위칭용 다이오드가 과열되는 것을 방지한 상태로 미스컨버젼스를 보정할 수 있다. 이것은 스위칭소자를 구비하는 모든 편향요크의 미스컨버젼스 보정장치에 매우 유용하다.The misconvergence correction device is a device for correcting misconvergence that is mounted in the deflection yoke so that the electron beam is not accurately scanned at each pixel.It is drawn from a pair of vertical deflection coils to correct the corner vertical generated in the corner portion of the screen in the vertical direction. In order to prevent overheating of the switching diode in series at the center tap, a thermal resistance that consumes the heat is connected to the diode. Therefore, the misconvergence can be corrected while preventing the switching diode from overheating. This is very useful for misconvergence correction devices of all deflection yokes with switching elements.
