Abstract

병렬 운전시에 각 변환기 사이의 출력균형을 손상하지 아니하고 안정된 제어를 할 수 있는 승압 변환기를 제공하는 것을 목적으로 하고 있다.
스위칭 소자(7) 및 다이오드(8)와 직렬로 변류기(22,23)를 접속한다.그들 변류기(22,23)에서의 검출전류에 의하여, 전류검출회로(21)에서 전류검출신호를 출력한다. 변환기 본체(3)의 내부에서 얻어진 전류검출신호와 병렬운전되는 다른 변환기 본체(3A)의 전류검출신호를 전류균형회로(33)에서 비교한다. 그리고, 그 비교결과에 의거하여 각 변환기 본체(3,3A) 사이의 직류출력전압 Vout가 동등하게 되도록 제어를 행한다.
