Abstract: 본 발명은 IGBT 등의 전력 반도체 소자(1)의 과전류 제한 기술에 관한 것이다.  종래의 과전류 보호 회로(1OP)에 따르면, 에미터 전류(i)와 전류 감지 전류 (is)가 과도 상태에서도 동일 동작을 나타내지 않은 경우에는 턴 오프 시에 전류 감지 전류가 순간적으로 증가하는 경향에 있어, 이 경우에는 과전류 보호 회로 중인 MOSFET(2P)의 통전 능력이 증대하여 IGBT(1P)의 턴 오프 스피드가 필요 이상으로 너무 빠르게 되는 결과, 서지 전압이 증대되는 문제점이 발생되고 있다.  그래서, 본 발명에서는 IGBT(1)의 과전류 보호 회로(10)에 있어서 MOSFET(2)의 게이트 전극(2G)과 소스 전극(2S) 사이에 MOSFET(2)의 임계치 전압 이상으로 설정된 순방향 전압을 갖는 다이오드(5)를 순방향으로 바이어스되도록 전압 클램프 회로(4)로서 설치하고 있다.  이에 따라, 감지 저항(3)으로 발생되는 전압치(is, R s )가 다이오드(5)의 순방향 전압 이상으로 도달하면, 다이오드(5)는 도통하여 MOSFET(2)의 게이트 전압을 순방향 전압에 클램프한다.
