Abstract
본 발명은 모니터의 전원 회로에 관한 것으로, 특히 트랜스 2차측의 전류를 센싱하여 센싱한 전류를 다시 트랜스의 1차측으로 피이드시켜 트랜지스터의 턴 온/오프 시간을 자동 제어해 주므로써 전원을 안정화 시켜 TR 및 IC를 보호해줄 수 있도록 파워 트랜지스터의 턴 온/오프 시간을 자동제어하여 전원을 안정화 시키는 전원 안정화 회로부를 구성한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply circuit of a monitor. In particular, the power supply is stabilized by automatically controlling the turn on / off time of a transistor by sensing the current on the secondary side of the transformer and feeding the sensed current back to the primary side of the transformer. And a power stabilization circuit that automatically stabilizes the power supply by controlling the turn-on / off time of the power transistor to protect the IC.
