Abstract
Description
Claims (1)
- 펄스폭 변조신호를 이용하여 서보모터를 구동시키는 자동 제어시스템에 있어서PWM신호가 입력되는 슈미트트리거회로(1)의 출력은 NOR게이트(2)일측입력에 연결함과 동시에 슈미트트리거회로(3)의 입력에 연결하되 슈미트트리거회로(3)의 출력은 NOR게이트(4)의 일측입력에 연결함과 동시에 저항(R1)과 병렬접속된 저항(R2)과 다이오드(D1)의 직렬회로를 통해 일단이 접지된 콘덴서(C1)의 타단에 연결하여 전력 트랜지스터의 역복귀전류 보상시간이 되는 소정의 지연시간을 갖도록하고 이 콘덴서(C1)의 타단은 슈미트트리거회로(5)를 통해 노아게이트(2)의 타측입력에 연결함과 동시에 슈미트트리거회로(6)를 통해 노아게이트(4)의 타측입력에 연결하여 상기 각 노아게이트(2, 4)의 출력에서는 보상시간을 갖는 PWM신호가 출력되도록 구성함을 특징으로 하는 펄스폭 변조신호 전달회로.
