Description
なお、参考態様では、目標電力指令として、2台のインバータに対する目標電力分配比率が指令されてもよい。その場合、電力制御部は、目標電力分配比率の急変の影響を抑えるようにフィルタ処理し、フィルタ処理後の目標電力分配比率に応じて、電力管理回路のdq軸電圧指令を調整する。
vq=R×Iq+ω×Ld×Id+ω×φ ・・・(1)
図8に第1実施形態の電力制御部401の構成を示す。第1実施形態では、目標電力指令として、2台のインバータ60、70に対する目標電力分配比率が電力制御部401に入力される。電力制御部401は、2台のインバータ60、70に対するdq軸電圧指令を電力分配比率により分配して得られる調整量を用いて、第2インバータ70の電圧指令を調整する。第1実施形態では、目標電力分配比率(すなわちゲイン)に応じて電圧指令を乗除算することで、分配応答性が向上する。
図9に第2実施形態の電力制御部402の構成を示す。第2実施形態では、目標電力指令として、電力管理回路側の第2インバータ70に対する目標電力量が電力制御部402に入力される。分配比率に応じた乗除算を基礎とする第1実施形態に対し、電力量そのものを加減算する第2実施形態では、誤差の増幅が無いため、分配安定性が向上する。
図10に第3実施形態の電力制御部403の構成を示す。第3実施形態では、目標電力指令として、2台のインバータ60、70に対する合計の目標電力量、及び、電力非管理回路側の第1インバータ60に対する目標電力量が電力制御部403に入力される。第2実施形態と同様に、電力量そのものを加減算する第3実施形態では、誤差の増幅が無いため、第1実施形態に比べ分配安定性が向上する。
(a)上記実施形態の電力制御部は、第1電圧指令ベクトル及び第2電圧指令ベクトルの位相を揃えることを前提とし、振幅のみを調整して電力分配を制御している。その他の実施形態では、2つの電圧指令ベクトルの振幅に加えて位相を調整してもよい。
200・・・制御部、
201・・・第1インバータ制御回路、
202・・・第2インバータ制御回路、
40・・・電力制御部、
60・・・第1インバータ、 61~66・・・第1スイッチング素子、
70・・・第2インバータ、 71~76・・・第1スイッチング素子、
80・・・MG(モータジェネレータ、電動機)、
81、82、83・・・3相巻線。
