Abstract

본 발명은 비안정멀티 바이브레이터를 이용하여 SMPS의 동작을 안정화시키는 안정화회로에 관한 것으로, 이를 해결하기 위해 전원분압부의 분압전압에 의해 동작되어 상기 스위칭 소자를 온/오프시키는 펄스신호를 공급하는 비안정멀티 바이브레이터; 비안정멀티 바이브레이터의 펄스신호에 의해 트랜스포머가 동작됨과 더불어 트랜스포머의 2차측단자에서 유기된 전압에 따라 전압검출부가 동작되어 비안정멀티 바이브레이터에 공급되는 전류값을 제어하는 포터커플러; 포터커플러의 동작에 연동되어 스위칭소자의 온/오스시간을 가변시키는 바랙터다이오드를 포함하도록 구성된다.The present invention relates to a stabilization circuit for stabilizing the operation of the SMPS by using an unstable multi-vibrator, in order to solve this problem is operated by the divided voltage of the voltage divider to supply an unstable to supply a pulse signal to turn on / off the switching element Multivibrator; A port coupler for operating the transformer by a pulse signal of the unstable multi-vibrator and controlling a current value supplied to the unstable multi-vibrator by operating a voltage detector according to the voltage induced by the secondary terminal of the transformer; It is configured to include a varactor diode that is linked to the operation of the porter coupler to change the on / off time of the switching element.
