Description
Claims (3)
- 히터저항(2)에 전류가 흐를때에 발생되는 저항열을 이용한 히터에 있어서, 온도변화에 거의 영향을 받지 않을 정도로 상기 히터저항(2)에 비해 상대적으로 큰 저항값을 갖는 기준저항(3)이 상기 히터저항(2)에 직렬로 연결되고, 상기 기준저항(3)과 히터저항(2)의 사이에는 전압 및 전류제어회로(6)가 연결되고, 상기 기준저항(3)의 양단에 연결된 전류검출용 A/D 변환앰프(5)와 상기 히터저항(2)의 양단에 연결된 히터 측정용 A/D 변환기(4)는 상기 전압 및 전류 제어회로(6)와 연결된 CPU 주회로(7)에 각각 연결됨으로써, 상기 히터저항(2)이 센서역할을 하므로 센서의 추가적인 사용이 필요치 않고 히터의 내부에서 변화되는 비저항계의 특성을 이용하여 피드백 제어되도록 구성되고, PWM 출력의 OFF 구간동안에는 상기 기준저항(3)의 회로 경로를 거치도록 제어하여(A 루프) 상기 기준저항(3)이 발열되지 않도록 최소 전압을 인가하여 히터(1)의 온도를 측정하고, PWM 출력의 ON 구간동안에는 히터가열회로의 효율을 향상시키기 위해 상기 기준저항(3)의 회로 경로를 차단하도록 제어함으로써(B 루프) 상기 히터(1)가 집중적으로 순간 가열되도록 함을 특징으로 하는 센서가 필요없는 히타용 온도 제어시스템.
- 삭제
- 제 1항에 있어서, A 루프를 통해 기준저항(3)에 흐르는 전류를 먼저 측정하고, 상기 전류값에 의해 히터저항(2)의 저항값을 계산한 다음 이 값과 전압변화에 따른 온도관계를 추정함으로써, 상기 CPU 주회로(7)에서는 적정온도의 도달여부를 판단하게되며, 가열이 필요한 경우에는 A 루프에서 B 루프로 전환되어 상기 히터(1)의 가열을 B 루프를 통해 순간적으로 가열되도록 하고, 다시 B 루프로 전환하여 온도측정과정을 반복하도록 제어함을 특징으로 하는 센서가 필요없는 히타용 온도 제어시스템.
