Abstract

스파이크 전압에 영향을 주지 않고 역기전압신호를 정확하게 인식하여, 안정 운전의 향상을 도모함을 목적으로, 스파이크 전압(g)은 정류에 의하여 통전상이 바뀌었을 경우에 발생한다. 역기전압의 제로 크로스 포인트를 나타내는 역기 전압신호(h)는 정류에서 다음회 정류까지의 동안에 발생하여, 스파이크전압(g)보다도 늦어지게 된다. 그 때문에, 금회의 정류의 발생(t1)에서 다음회의 정류의 발생(t2)까지의 사이에 부여되는 신호중에서 최후의 것을 유효한 역기전압신호로 인식하여, 스파이크전압(g)의 영향을 제거한다.The spike voltage g is generated when the energization phase is changed by rectification for the purpose of accurately recognizing the counter electromotive voltage signal without affecting the spike voltage and improving the stable operation. The counter voltage signal h, which represents the zero cross point of the counter voltage, is generated from rectification to the next rectification, which is later than the spike voltage g. Therefore, the last one of the signals applied from the current generation t 1 to the next generation t 2 is recognized as a valid counter electromotive signal, thereby eliminating the influence of the spike voltage g. do.
