Abstract
태양광 모듈의 출력단에 다이오드를 거쳐 스위칭 수단인 2개 씩의 전계효과 트랜지스터의 소스에 병렬로 접속하고,
상기 전계효과 트랜지스터의 드레인-소스와 병렬로 콘덴서 및 다이오드를 접속하여 전계효과 트랜지스터를 경유하는 중에 승압된 교류 전원이 출력되도록 하고,
상기 스위칭 수단인 2개 씩의 전계효과 트랜지스터의 게이트에는 드라이버로부터 구형파가 60Hz의 주기로 교대로 공급되어 온시키도록 하고,
60Hz의 주기로 교대로 온 되는 상기 스위칭 수단인 2개 씩의 전계효과 트랜지스터의 드레인에서는 변환된 교류 전원이 트랜스포머의 중간 탭이 접지된 1차측의 양단에 인가되도록 하고,
다수의 스위칭 수단인 2개 씩의 전계효과 트랜지스터의 드레인으로부터 출력되는 변환된 교류 전원이 직렬로 배열한 트랜스포머의 다수의 1차측 각각 인가되도록 함으로써 트랜스포머의 2차측에서 안정되게 승압된 교류 전원을 고효율로 얻도록 고효율로 얻도록 구성한 것이다.
