Claims (5)
- 정전압원과 부하(load) 사이에 개재되어 상기 부하에 정전압이 공급되도록 하는 전원공급 보호장치에 있어서,
상기 정전압원의 출력단에 순방향 접속되어 역방향 전류 흐름을 차단하는 다이오드와;
상기 다이오드의 캐소드 단자와 상기 정전압원 사이에 접속되어 상기 정전압원으로부터 공급되는 전력을 이용해 충전되고, 충전된 전력을 상기 부하로 방전 공급하는 배터리와;
상기 다이오드와 상기 배터리의 접속 노드와 상기 부하 사이에 접속되어 이상 과전류 발생시 배터리 보호를 위해 전류 흐름을 차단하는 스위칭소자; 및
상기 다이오드의 상기 캐소드 단자와 상기 배터리 사이에 접속되어 상기 배터리 및 상기 부하로의 전류량을 제한하는 전류 제한기를 포함하며,
상기 부하는 고전력 단주기성 부하인 것을 특징으로 하는 전원공급 보호장치.
- 삭제
- 제 1 항에 있어서, 상기 스위칭소자는
LCL(Latching Current Limiter), 계전기(Relay)와 퓨즈의 조합, 트랜지스터 중 어느 하나로 구성되는 것을 특징으로 하는 전원공급 보호장치. - 삭제
- 삭제
