Claims (9)

  1. 비상상태가 극성 반전으로 표시되는 비상 D.C.전원공급기에 있어서, 양단 전압부재시에 출력을 고임피던스 상태로 되게 하는 보호장치를 갖춘 주 D.C.전원, 및 주전원과 별렬 및 반대로 접속되고 주전원이 부여하고저 하는 부가 전류에 의해 통상적으로 차단되는 전류제한 장치를 갖춘 보조 D.C.전원을 포함하는 것을 특징으로 하는 공급기.
  2. 제 1 항에 있어서, 주전원의 보호장치가 전류제한 장치를 갖추고 있는 것을 특징으로 하는 전원공급기.
  3. 제1항에 있어서, 보조전원의 전류제한 장치가 보조전원으로부터 출구를 양단 전압 부재시에 고임피던스상태로 통과시키는 장치를 갖추고 있는 것을 특징으로 하는 전원공급기.
  4. 제 1 항에 있어서, 주전원 및 보조 전원이 전류가 역방향으로 흐르는 것을 방지하는 각각의 비-복귀다이오드를 갖추고 있는 것을 특징으로 하는 전원공급기.
  5. 제 1 항에 있어서, 주전원의 보호장치가 직렬로 접속되고, 주전원의 2개의 단자들간에서 발생된 전압에 의해 가동되며, 비가동 상태일 때 고 임피던스 상태로 통과하는 것을 특징으로 하는 전원공급기.
  6. 제 5 항에 있어서, 주전원의 보호장치가 직렬저항을 통해 주전원의 단자에 접속된 제너 다이오드를 통해 주전원에 의해 제공된 전압에 의해 가동되는 것을 특징으로 하는 전원공급기.
  7. 제 1 항에 있어서, 보조전원의 전류 제한 장치가 가변임피던스의 안정회로, 보조전원의 전류경로내에 직렬로 접속된 전류측정저항, 및 전류측정 저항의 양단 전압의 함수로서 안정회로를 제어하기 위한 제어장치를 포함하는 것을 특징으로 하는 전원공급기.
  8. 제7항에 있어서, 안정 회로가 온/오프 스위치되는 트랜지스터이고, 안정 회로를 제어하기 위한 제어장치가 전류측정 저항의 전압에 민감한 임계치 비교기에 의해 차단된 단안정 회로를 포함하는 것을 특징으로 하는 전원공급기.
  9. 제 1 항에 있어서, 보조전원의 전류 제한 장치가 보조전원의 양단에서 발생된 전압에 의해 가동되고, 비가동 상태일때는 고임피던스 상태로 스위치되는 것을 특징으로 하는 전원공급기.
