Abstract
【解決手段】直流電流をスイッチングさせることにより、疑似交流電流を生成してモータ3を駆動するインバータ装置10において、モータ3に印加される二次電流に基づいてベクトル制御を実行するコントローラ9を備え、コントローラ9は、二次電流から電流密度を算出し、算出された電流密度に基づいて所定の保護動作を実行する。コントローラ9は、電流密度に基づいてモータ3の運転周波数に制限を加える。
【選択図】図2
Description
W=√3×Vrs×Ir×COSθ1
電源が直流電源の場合、消費電力は、
W=Vdc×Idc
であり、二次側から求めた消費電力は、
W=√3×Vuv×Iu×COSθ2
となる(Wは消費電力、Vrsは一次電圧、Irは一次電流、Vuvは二次電圧、Iuは二次電流、COSθは力率である)。
Iu=(Vrs×Ir×COSθ1)/(Vuv×COSθ2)
又は、
Iu=(Vdc×Idc)/(√3×Vuv×COSθ2)
となる。従って、二次電流を求めるためには、力率やVrs、Vuv、Vdcの値が必要となり、これらに誤差があると二次電流を正確に推定することは困難であった。
