Claims (2)
- 인버터 전력트랜지스터의 구동회로에 있어서, PWM 파형을 입력으로 하고 그 파형의 레벨에 상응하여 온/오프 동작하는 포토커플러부(8)와; 상기 포토커플러부(8)로 부터의 출력신호에 따라 상기 전력트랜지스터(23)의 베이스전류를 제어하기 위해 두개의 트랜지스터(41, 42)를 구비한 트랜지스터부(9)와; 상기 트랜지스터(42)의 콜렉터측과 상기 전력트랜지스터(23)의 베이스측 사이에 배치되어 상기 전력트랜지스터(23)를 턴오프 제어하는 트랜지스터부(10)와; 상기 전력트랜지스터(23)의 에미터측에 접속되어 그의 온/오프 변동시간을 일정하게 유지하기 위한 부전원 발생부(11)로 이부어진 것을 특징으로 하는 인버터 전력트랜지스터 구동회로.
- 상기 전력트랜지스터(23)의 온/오프 변동시간을 일정하게 유지하기 위한 상기 부전원발생부(11)가 서로 직렬 접속된 세개의 다이오드(D1, D2, D3)에 병렬 접속되는 콘텐서(C1)로 구성됨을 특징으로 하는 인버터 전력 트랜지스터 구동회로.
