Claims (4)

  1. 직류회로의 전력과 교류-회로의 전력을 전류지령신호에 의하여 상호변환시키는 인버터회로와, 상기 직류회로의 전압분압점에 전류검출회로의 일단을 접속시키고 이 전류검출회로의 타단을 미분회로를 통하여 상기 인버터회로의 교류단자에 접속시킨 주회로 전류검출회로와, 이 주회로전류검출회로의 검출신호와 상기인버터회로에 전류를 지령하는 전류지령신호를 비교하여 양신호의 임의의 시간내에서 논리모순을 검출하는 전류이상판정논리회로등을 구비한 인버터회로의 이상검출장치.
  2. 청구범위 제1항에 있어서, 상기 주회로전류검출회로와 복수개의 미분회로의 일단을 접속하고, 타단을 인버터회로의 복수개의 교류단자에 각각 접속하며, 복수개의 인버터회로의 전류현상을 공통의 전류검출회로에서 검출하도록 구성시킨것을 특징으로 하는 인버터의 이상검출회로.
  3. 청구범위 제1항 또는 제2항에 있어서, 상기 전류검출회로로서, 전류방향을 동시에 검출하는 회로를 가진 것을 특징으로 하는 인버터의 이상검출장치.
  4. 청구범위 제1항 또는 제2항에 있어서, 상기 전류검출회로로서, 전류방향을 검출하지 않은 회로에 의하여 구성을 시킨 것을 특징으로 하는 인버터의 이상검출장치.
