Abstract
Description
Claims (3)
- 전자기기의 전원회로에 있어서, 두 레벨의 전압을 절환스위치에 의하여 선택 입력하여 직류로 변환하는 직류 전압발생부와, 상기 직류 전압의 크기를 검출하는 전압검출부와, 상기 직류 전압의 접속 경로를 차단하는 전원차단부와, 경보음발생부와, 전원차단부를 통하여 직류 전압을 인가받아 일정 크기로 정형하는 레귤레이터를 구비하며, 전압 검출부에서 검출되는 전압이 정상상태로 벗어날 때에는 전원차단회로를 동작하여 전원을 차단하고, 동시에 경보음 발생부를 동작하여 경보음을 발생함을 특징으로 하는 전원회로.
- 전자기기의 전원을 공급하는 방법에 있어서, 상기 교류 전압을 직류전압으로 변환하는 제1단계와, 상기 직류 전압의 크기를 검출하는 제2단계와, 검출된 전압이 기 설정된 일정상태를 벗어나는 경우에는 경보음을 발하는 제3단계로 이루어짐을 특징으로 하는 전원공급 방법.
- 전자기기의 전원을 공급하는 방법에 있어서, 상기 교류 전압을 직류 전압으로 변환하는 제1단계와, 상기 직류 전압의 크기를 검출하는 제2단계와, 상기 제2단계의 결과에 따라 전원을 차단하고 경보음을 발하거나 또는 레귤레이터에 상기 직류 전압을 공급하여 정형하는 제3단계로 이루어짐을 특징으로 하는 전원공급 방법.
