Abstract
Description
Claims (1)
- 직류전원을 인가받아 전력트랜지스터의 동작에 의하여 교류전원으로 변환시키는 인버터회로의 자가진단 방법에 있어서, 상기 인버터회로의 운전동작 이전에 전력트랜지스터에 최대폭을 지닌 구동펄스를 순차적으로 인가하여 동시에 턴온되는지를 검출하는 단계(11-16), 상기 단계에서 전력트랜지스터가 동시에 턴 온되면 정보와 함께 인버터회로의 운전을 정지하는 단계(18, 19), 상기 단계에서 동시에 턴 온되지 않으면 인버터회로의 부하측인 유도전동기에 과전류를 인가하고 순간전류검출부에서 인가된 과전류를 검출하는지를 검사하는 단계(20-21), 상기 단계에서 과전류를 검출하지 못할 경후에 경보와 함께 인버터회로의 운전을정지하는 단계(22), 상기 단계에서 과전류를 검출할 경우에 인버터회로의 정상운전을 시작하는 단계(23)으로 이루어진 것을 특징으로 하는 인버터 구동회로의 자가진단 방법.
