Abstract
Description
Claims (6)
- 기본용량단위의 전력변환기능을 하는 다수의 컨버터(50a)(50b)들과, 입력 전압에 따라 사용자에 의해 절환되어 상기 컨버터(50a)(50b)들을 직렬 또는 병렬연결상태로 절환시키는 스위치부(20)로 구성된 것을 특징으로 하는 직·병렬 조합형 컨버터회로.
- 제1항에 있어서, 상기 입력전압이 AC전압으로서, 이 AC입력전압을 정류하여 상기 컨버터(50a)(50b)로 공급하는 정류부(10)가 추가로 구비된 것을 특징으로 하는 직·병렬 조합형 컨버터회로.
- 제1항에 있어서, 상기 스위치부(20)가 서로 상반되게 "온/오프" 동작되어 상기 컨버터(50a)(50b)들을 직렬 또는 병렬로 접속시키는 연동접점(a1)(a2) 및 접점(b)으로 구성된 것을 특징으로 하는 직·병렬 조합형 컨버터회로.
- 제1항에 있어서, 상기 컨버터회로의 출력용량증가에 따라, 병렬연결된 다수의 컨버터들을 기본단위로 하여 다수쌍의 상기 컨버터들로 상기 컨버터회로를 구성하는 것을 특징으로 하는 직·병렬 조합형 컨버터회로.
- 제1항에 있어서, 상기 각 컨버터(50a)(50b)의 전단에 각각 연결되어, 상기 컨버터(50a)(50b)의 직렬연결시 어느 한쪽 컨버터로의 회로 불평형 현상을 방지 하기 위한 역률보상부(40a)(40b)가 추가로 구비된 것을 특징으로 하는 직·병렬 조합형 컨버터회로.
- 제1항에 있어서, 상기 각 컨버터(50a)(50b)의 전단에 각각 연결되어, 상기 컨버터(50a)(50b)들로 입력되어 돌입전류를 제한하기 위한 돌입전류방지부(30a)(30b)가 추가로 구비된 것을 특징으로 하는 직·병렬 조합형 컨버터회로.
