Abstract
위상차가 클 경우의 응답성 및 안정운전의 향상을 도모하고, 또 진각량을 자유로이 변경하는 것을 가능하게 하는 것을 목적으로 하고 있으며, 현재의 정류주기 (Tn-1)의 개시로 부터 제로 크로스 펄스 (Zr)가 부여되어야 할 목표 제로 크로스 시간(tref)을 현재의 정류주기 (Tn-1)에 기초하여 설정한다. 목표 제로 크로스 시간 (Tref)과 현재의 정류주기 (Tn-1)의 개시로 부터 제로 크로스 펄스 (Zr)가 실제에 부여된 실제 제로 크로스 시간(tact)과의 차 (Δtn-1)에 따라서, 제로 크로스 펄스 (Zr)가 목표 제로 크로스 시간 (tref)에 부여되도록 비례 및 적분연산함에 따라 다음회의 정류주기 (Tn)를 결정한다.It aims to improve the response and stable operation when the phase difference is large, and to make it possible to freely change the advance amount, and zero cross pulse from the start of the current rectification period (T n-1 ). A target zero cross time t ref to which (Z r ) should be given is set based on the current rectification period T n-1 . Difference (Δt n− ) between the target zero cross time (T ref ) and the actual zero cross time (t act ) to which the zero cross pulse Z r is actually given from the start of the current rectification period (T n-1 ). According to 1 ), the next commutation period T n is determined in accordance with the proportional and integral operation such that the zero cross pulse Z r is given to the target zero cross time t ref .
