Abstract

가열장치의 전기히터를 반도체스위치로 주기에 인가되는 전원을 차단 및 공급한다. 상기 반도체 스위치는 트리거부에 의해 차단 및 도통상태로 되며 제로크로스감지부는 교류전원의 제로크로스시점을 감지하고, 온도감지부는 상기 가열장치의 온도를 감지한다.The electric heater of the heating device is cut off and supplied to the cycle by the semiconductor switch. The semiconductor switch is cut off and in a conductive state by a trigger unit, the zero cross detector detects a zero cross time point of the AC power, and the temperature detector detects a temperature of the heating device.

제어부는 상기 제로크로스감지부와 상기 온도감지부로 부터 데이타를 받아 외부교류전원의 반주기동안 소정트리거 위상각에서 히터를 구동하고 다음 반주기에서도 동일하게 구동하고 한주기가 끝나면 트리거위상각을 소정각 감소시켜 구동하여 트리거위상각이 소정각도가 된 이후는 교류전원을 계속히터에 인가한다.The controller receives data from the zero cross detector and the temperature detector and drives the heater at a predetermined trigger phase angle during the half cycle of the external alternating current power source.The controller drives the same in the next half cycle and decreases the trigger phase angle by a predetermined angle after one cycle. Therefore, after the trigger phase angle reaches a predetermined angle, AC power is continuously applied to the heater.
