(제3도의 a)도와 같이) 이때 펄스의 입력 크기는 제너다이오드(ZD1)에 의하여 결정되고 플립플롭(FF1)의 입력동작범위로 결정할 수 있다.The half-wave rectification is performed through the diode D 1 (D 2 ) in the AC220V power supply, and a pulse corresponding to a half cycle of 60 (HZ) is input to the clock terminal CK of the flip-flop FF 1 . In this case, the input size of the pulse may be determined by the zener diode ZD 1 and may be determined by the input operation range of the flip-flop FF 1 .

이를 다음식으로 살펴보면,If you look at this as

이와같이 220볼트의 입력전압을 강압시켜서 110볼트를 얻게된다. 그리고 제로 크로싱(zero-crossing)트라이액 구동 집적회로(IC1)를 이용하여 전원전압의 영볼트에서 트라이액(T)의 게이트에 전류를 공급할 수 있게하여 게이트펄스를 집적회로(IC1)의 단자점(1)에 상기의 앤드게이트(G1)의 출력단자에 출력된 펄스를 입력시켜서 집적회로(IC1)의 단자점(4)에서 최종 게이트펄스를 트라이액(T)에 인가하게 된다.In this way, the voltage is reduced to 220 volts to obtain 110 volts. In addition, the zero-crossing triac driving integrated circuit IC 1 is used to supply a current to the gate of the triac T at zero volts of the supply voltage, thereby providing a gate pulse to the integrated circuit IC 1 . The final gate pulse is applied to the triac T at the terminal point 4 of the integrated circuit IC 1 by inputting the pulse output from the output terminal of the AND gate G 1 to the terminal point 1 . .

이때 센시티브게이트(sensitive 게이트)를 충족시키고자 저항(R7)을 연결하고 저항(R6)에 의해 게이트전류는 100(mA) 이하로 하였다.At this time, in order to satisfy the sensitive gate (sensitive gate), a resistor R 7 was connected and the gate current was set to 100 (mA) or less by the resistor R 6 .

이와같이 트라이액(T)에 직열로 연결된 부하는 1싸이클 온 3싸이클 오프로 전원전압이 220볼트에서 실효전압 110볼트에 해당하는 전력을 얻을 수 있게 된다.In this way, the load connected in series with the triac (T) is one cycle on three cycles off, so that the power supply voltage is 220 volts to obtain the power corresponding to the effective voltage 110 volts.
