Description
前記PWMインバータに指令される前記ベクトル演算制御に使用される周波数指令値と電圧指令値と該PWMインバータが出力する電流の座標変換した値に基づいて該PWMインバータの出力する電圧と電流の位相角を推定演算し、前記電圧指令値の零クロス点から電気角で90°遅れた位置に前記位相角を加算演算した位置が前記オン・オフ状態を固定した区間のほぼ中心となるように制御することを特徴とする。
Claims (1)
- ベクトル演算制御の過程で、三相ブリッジ回路の各アームのうち1アームのオン・オフ状態を固定しておき、残りの2アームのみをPWM制御する2アーム変調方式を用いてなるPWMインバータの制御方法において、
