Abstract

본 발명은 110V/220V 전원을 겸용하여 정류전원으로 사용하는 게이트 신호 발생 안정화회로에 관한 것으로, 종래에는 110V/220V 절환시 전원을 두개 따로 사용해야 함으로 제품의 부피가 커지게 되고, 무리하게 하나의 전원을 쓰면 소자의 과부하로 회로손상 및 수평단축의 문제점이 생기며, 트라이액의 게이트신호가 온/오프 동작을 반복하여 진동하므로 회로가 불안정하였다.The present invention relates to a gate signal generation stabilization circuit using a 110V / 220V power supply as a rectified power supply, and in the related art, two separate power supplies must be used when switching 110V / 220V, the volume of the product becomes large, one power supply unreasonably In this case, the overload of the device causes circuit damage and horizontal shortening, and the circuit signal is unstable because the triac gate signal vibrates on and off repeatedly.

이러한 문제점들을 감안하여 하나의 전원을 사용하면서도 트라이액의 게이트신호를 안정화하기 위하여 검출된 전압신호를 정류된 직류전압이 충분히 충전될때까지 일정시간이 지난후 게이트 신호를 출력함으로써 원가절감 및 신뢰도 향상의 효과를 얻을 수 있게 된다.In consideration of these problems, the gate signal is output after a certain time until the rectified DC voltage is sufficiently charged to stabilize the gate signal of the triac while using a single power supply. You will get the effect.
