Abstract

전기요의 제어회로에 관한 것으로 발열체의 온도에 따른 캐패시턴스에 의한 지연전압으로 트라이악을 온 오프시켜 열선에 가해지는 입력전압을 위상제어함에 따라 온도 상승 곡선이 완만하고 회로에 잡음이 발생하나 마이콤에 의해 제로크로싱제어를 제어함으로 설정온도에 도달시간이 짧고, 회로 동작이 안정된다.The control circuit of the electric yaw is related to the phase control of the input voltage applied to the heating wire by turning the triac on and off with the delay voltage caused by the capacitance according to the temperature of the heating element. By controlling the zero crossing control, the time to reach the set temperature is short and the circuit operation is stabilized.

또한 마이콤에 의하여 입력전압에 관계없이 일정하게 온도제어를 하고 전기요에 조절기의 접속여부, 회로와 마이콤의 이상을 체크하고 취소기능, 취침기능, 알람기능, 예약기능을 할 수 있다.In addition, by the microcomputer, the temperature control is constant regardless of the input voltage, and it is possible to check whether the controller is connected to the electric cable, the abnormality of the circuit and the microcomputer, and the cancel function, the sleep function, the alarm function, and the reservation function.
