본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 의한 회로 개략도.
제2도는 전부하 조건하에서 도시한 유도전동기에 전체 공급전압을 가하기 위한 제1장치를 포함한 본 발명에 의한 회로 개략도.
제3도는 전부하 조건하에서 도시한 유도전동기에 전체 공급전압을 가하기 위한 제2장치를 포함한 본 발명에 의한 회로 개략도.
제4도는 제1, 2 및 3도에 도시한 회로의 동작을 예시한 여러가지 전압과 전류의 그래프.

Claims (1)

  1. 본문에 상술하고 도면에 도시한 바와 같이, 교류전원과 게이트제어된 모터-에너지화(motor-energizing)반도체 스위치에 직렬로 되어있는 유도전동기에 교류 공급전압을 가하는 시간을 조절하여 최대치미만으로 부하된 교류 유도 전동기의 역률을 최적화시키는 방법으로서 전동기의 회전자가 자유로이 회전하는 반도체 스위치의 비통전 주기중에 그 전동기에 의해 발생되어 그 전동기의 회전자축에 걸리는 기계적인 부하의 함수로서 변하는 제어전압의 진폭에 따라서 그 반도체 스위치의 통전주기를 변화시키는 단계로 구성된 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
