Claims (7)

  1. 2차측에서 형성된 제어전압(Ur1)이 1차측으로 전달되어 그곳에서 작동전압의 안정화를 위하여 스위칭 트랜지스터(T1)용 제어회로(4)의 제어단자(a)에 작용하는 전원회로장치에 있어서, 2차측을 기초로하는 제어기능 정지시에 상기 제어단자(a)는 자동적으로 1차측에서 형성된 제2의 제어전압(Ur2)으로 전환되고, 이 제어 전압에 의해 작동전압(U1,U2)이 감소된 값으로 제어되는 것을 특징으로 하는 전원회로장치.
  2. 제1항에 있어서, 2차측에서 형성된 제어전압(Ur1)은 변조기(10-12)에서 펄스전압으로 변환되고, 이 펄스전압은 부가적 변성기(15)를 통하여 1차측으로 전달되고, 그곳에서 다시 정류(17)되는 것을 특징으로 하는 전원회로장치.
  3. 제2항에 있어서, 변조 펄스전압은 회로전원부변성기(2)의 2차권선(6)으로부터 도출되는 것을 특징으로 하는 전원회로장치.
  4. 제1항에 있어서, 제2의 제어전압을 유도하는 회로점(c,a)은 통상동작시에 차단되어 있는 다이오드(22)를 통하여 제어단자(a)에 접속되어 있는 것을 특징으로 하는 전원회로장치.
  5. 제2항 또는 제4항에 있어서, 회로점(c,d0는 콘덴서(23)와 트랜지스터(24)의 병열회로에 의하여 접지되고, 이 트랜지스터의 베이스에는 부가적 변성기(15)의 1차권선(16)으로부터의 펄스전압이 인가되는 것을 특징으로 하는 전원회로장치.
  6. 제1항에 있어서, 감소된 값은 정격치보다 10% 밑도는 값까지인 것을 특징으로 하는 전원회로장치.
  7. 제1항에 있어서, 제2의 제어전압(UR2)에 의한 동작상태인 것을 보여주는 표시기(LED)가 설치되어 있는 것을 특징으로 하는 전원회로장치.
