Claims (3)

  1. 유도성 부하의 통전 전류가 차단된 때에 발생하는 서지를 흡수하는 서지흡수회로에서의 출력에 기인하여 상기 서지량을 기준치와 비교하는 서지비교회로, 이 서지 비교회로에서의 출력에 기인하여 상기 서지량이 상기 기준치를 초과하고 있는 시간이 설정범위에 없을 경우, 고장신호를 출력하는 서지시간 판별회로를 구비한 유도성 부하구동회로의 고장검출회로.
  2. 제1항에 있어서 서지시간 판별회로는 서지량이 기준치를 초과하고 있는 시간이 소정시간에 미만인 경우에 고정신호를 출력하는 것을 특징으로하는 유도성 부하구동회로의 고장검출회로.
  3. 제1항 또는 제2항에 있어서 서지시간 판별수단은 유도성부하의 통전 전류를 제어하는 지령신호에 동기하여 서지량이 기준치를 초과하고 있는 시간을 구비하는 것을 특징으로 하는 유도성 부하구동회로의 고장 검출회로.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
