Abstract

본 발명의 목적은 카운터를 이용한 4개의 출력측에 포토커플러와 저항을 연결한 매우 간단한 회로로서 생상원가가 저렴한 위상제어회로를 제공하도록 하고, 위상폭을 임의로 선택한 단계를 디스플레이 상을 확인하면서 위상폭을 조정 선택할 수 있게 하였으므로 부하의 위상폭을 정확하게 미세조정할 수 있도록 한 것이다.An object of the present invention is to provide a phase control circuit having a low cost of production as a very simple circuit connecting a photocoupler and a resistor to four outputs using a counter, and checking the phase of the phase while arbitrarily selecting a phase width. Since the adjustment can be selected, the phase width of the load can be finely adjusted.

본 발명은 상기와 같은 목적을 달성하기 위하여 AC전원을 부하에 연결하고 이 부하의 공급전원 제어하여 위상을 제어하도록 함에 있어서; 업ㆍ다운을 선택하고 입력을 선택제어하는 입력선택부(10)와; 이 입력선택수단에 의해서 선택신호를 클럭으로하여 카운팅하는 카운터(20)와; 이 카운터의 츨력신호에 의해 스위칭되는 스위칭부(30)와; 이 스위칭수단의 출력신호에 의해서 충ㆍ방전되고 트리거 신호를 출력하는 트리거부(40)와; 이 트리거수단의 출력신호에 의해 상기 부하의 전원을 제어하는 제어수단을 구성한 것을 특징으로 하는 위상제어 회로이다.The present invention is to connect the AC power to the load in order to achieve the above object to control the supply power of the load to control the phase; An input selector 10 for selecting up / down and controlling selection of an input; A counter 20 which counts the selection signal as the clock by the input selection means; A switching unit 30 which is switched by an output signal of this counter; A trigger unit 40 which is charged and discharged by an output signal of the switching means and outputs a trigger signal; A phase control circuit comprising a control means for controlling a power supply of the load by an output signal of the trigger means.
