Abstract

본 발명은 콤프레서를 정지시키는 일없이 보호동작을 행하도록 하는 동시에 반도체 소자의 파괴를 확실히 방지할 수 있도록 하는 냉동 사이를 제어장치에 관한 것으로, 듀티제어회로(15)는 듀티 설정기(17), 주기 카운터(18)클럭발진기(19)에서의 신호에 기초해, 미리 설정된 듀티로 PWM 제어 펄스신호를 베이스 드라이버(5)에 출력한다. 듀티제한회로(16)는, 인버터회로(4)에서 콘버터회로(2)로 흐르는 전류 I가 과전류 레벨에 도달한 것을 전류 검출회로(9)에서의 신호에 의해 검출하면, 제한신호로서의 리셋신호를 주기마다에 듀티제한회로(15)에 출력하고, PWM 제어신호의 듀티를 일정범위내로 제한한다. 이에 전류 I가 감소하기 때문에, 콤프레서(6) 및 콤프레서 모터(7)의 운전을 정지하고 않고도 인버터 회로(4)내의 트랜지스터의 파괴를 방지할 수 있는 것을 특징으로 한다.
