Abstract

본 발명은 전압변동이나 온도변화에 관계없이 마그네트론의 출력이 항상 일정하게 유지되도록 하는 전자레인지의 출력안정화회로 및 그 방법에 관한 것으로, 이러한 본 발명은 전류트랜스(CT2)에 의해 검출된 마그네트론 (MGT)의 양극전류값을 배합회로(5)를 통해 마이콤(10)에 입력시키고, 마이콤(10)에서는 이 값을 정격 양극전륭과 비교하여 정격전류량이 적으면 출력데이타를 감소시켜 병렬저항(RO-R4)값을 크게 함으로써 비교기(CDMP1)의 기준전압을 상승시키고, 검출전류값이 정격전류값보다 많으면 출력데이타를 증가시켜 상기 기준전압을 하강시키게 된다.
