Abstract:
(EN) An inverter circuit 22 converts DC power into AC power. A filter circuit 23 has a reactor L1, and attenuates the high-frequency component of AC power outputted by the inverter circuit 22. A current detection circuit 25 detects the current flowing through the reactor L1. A control circuit 27 generates a drive signal of the inverter circuit 22 on the basis of a voltage command value. On the basis of the current detected by the current detection circuit 25, the control circuit 27 estimates the output voltage of the inverter circuit 22 prior to passage through the filter circuit 23, and corrects the voltage command value on the basis of the relation between the estimated output voltage of the inverter circuit 22 and the drive signal supplied to the inverter circuit 22.
(FR) Cette invention concerne un circuit onduleur (22) qui convertit une puissance en CC en une puissance en CA. Un circuit filtrant (23) comprend une bobine réactive (L1), et atténue la composante haute fréquence de la puissance en CA délivrée en sortie par le circuit onduleur (22). Une unité de détection de courant (25) détecte le courant traversant la bobine réactive (L1). Un circuit de commande (27) génère un signal d'excitation du circuit onduleur (22) sur la base d'une valeur de commande de tension. Sur la base du courant détecté par le circuit de détection de courant (25), le circuit de commande (27) estime la tension de sortie du circuit onduleur (22) avant le passage à travers le circuit filtrant (23), et corrige la valeur de commande de tension sur la base de la relation entre la tension de sortie estimée du circuit onduleur (22) et le signal d'excitation fourni au circuit onduleur (22).
(JA) インバータ回路22は直流電力を交流電力に変換する。フィルタ回路23は、リアクトルL1を有し、インバータ回路22の出力する交流電力の高周波成分を減衰する。電流検出回路25はリアクトルL1に流れる電流を検出する。制御回路27は電圧指令値をもとにインバータ回路22の駆動信号を生成する。制御回路27は、電流検出回路25で検出された電流に基づいてフィルタ回路23を通過前のインバータ回路22の出力電圧を推定し、推定したインバータ回路22の出力電圧と、インバータ回路22に供給される駆動信号との関係に基づき電圧指令値を補正する。
