Abstract
Description
Claims (1)
- 전압의 크기가 다양한 외부 입력 전원을 받게 되는 전원 입력부(10)를 구비하고, 상기 전원 입력부(10)로 입력된 전원은 실효치 값을 구한 후 이를 DC로 변환시켜 입력 전압에 대응되는 DC를 얻도록 하는 전압 변환부(20)를 구비하며, 상기 전압 변환부(20)의 DC 출력을 디지털 데이터로 변환시키는 디지털 변환기(30)를 구비하고, 상기 디지털 변환기(30)의 출력 값은 중앙처리장치로 입력되어 미리 입력 전압에 대응되게 입력시킨 디지털 데이터 값과 비교하여 서로 일치하는 출력전압을 선택하기 위한 선택신호를 출력시키는 연산장치(40)를 구비하며, 상기 연산장치(40)의 선택신호에 의해 입력 전압으로부터 출력전압을 선택하는 스위칭수단(50)을 구비하여 된 것을 특징으로 하는 전압 자동 선택장치.
