Claims (7)

  1. 편차로부터 얻어진 펄스폭 변조된 신호(3)는 2개의 서로 다른 높은 직류전압 (+U, -U)사이에서 전환 스위치(4)의출력을 전환 스위칭하며 또한 출력은 아날로그 제어전압(Ur)을 제공하는 저역필터(5)의 입력과 연결되어 있는 제어 회로에 있어서, 저역필터(5)의 입력은 편차(f1,f2)에 따라 동작하는 선택스위치(7)를 거쳐 펄스폭 변조된 동일신호(3)에 의해 제어된 제2의 전환스위치(4b)의 출력에 스위칭될 수 있으며, 다른 크기(±8V)의 직류전압이 제1의 전환스위치(4a)로 부터 상기 전환스위치(4b)에 인가되는 것을 특징으로 하는 제어회로.
  2. 제1항에 있어서, 전환스위치(4a,4b)의 각각의 입력에 인가된 2개의 직류전압 (±1V;±8V)가 반대부호의 동일값을 가지는 것을 특징으로 하는 제어회로.
  3. 제1항에 있어서, 인가된 작은 직류전압(±1V)을 가지는 제1의 전환스위치(4a)가 100%의펄스폭변조 및 작은 주파수편차(±f1)에 대한 미세 제어범위를 위해 제공되며 인가된 더 큰 직류전압(±8V)를 가지는 제2의 전환스위치(4b)가 100%펄스폭 변조 및 큰 주파수 편차를 가지는 개략 제어범위(B2)를 위해 제공되는 것을 특징으로 하는 제어회로.
  4. 제3항에 있어서, 미세제어범위(B1)로 부터 개략제어범위(B2)로의 전이점(P)에서 PWM의 변조 깊이는, 만들어진 아날로그 제어전압(Ur)의 연속파형이 2개의 제어범위(B1,B2)에 걸쳐 발생하도록 효과적인 각각의 전환스위치(4a,4b)에 인가된 직류전압(1V,8V)의 상승에 따라 감소되는 것을 특징으로 하는 제어회로.
  5. 제1항에 있어서, 2개의 전환스위치(4a,4b)와 선택스위치(7)는, 다른 높은 직류전압(1V,8V)이 선택적으로 입력에 인가되는 그 입력을 가진 전환스위치로 바뀔수 있는 것을 특징으로 하는 제어회로.
  6. 제1항에 있어서, 전환스위치(4a)에 의해 형성된 미세제어범위(B1)의 위치는 다른 전환 스위치(4b)에 의해 형성된 개략제어범위(B2)내의 알맞은 장소에 놓이는 것을 특징으로 하는 제어회로.
  7. 제6항에 있어서, 미세제어범위(B1)의 폭과 분해능은 개략제어범위(B2)에 비해 작은 것을 특징으로 하는 제어회로.
