(EN) POWER CONVERSION DEVICE
(FR) DISPOSITIF DE CONVERSION DE PUISSANCE
(JA) 電力変換装置
要約
(EN) This power conversion device comprises: a power converter including a switching element; and a control unit which controls the power converter. The control unit calculates a torque electric current detection value and an excitation electric current detection value from an electric current flowing to an external device, and when an absolute value of the torque electric current detection value is greater than or equal to the excitation electric current detection value, performs control such that the excitation electric current detection value follows the torque electric current detection value.
(FR) La présente invention concerne un dispositif de conversion de puissance qui comprend : un convertisseur de puissance comprenant un élément de commutation; et une unité de commande qui commande le convertisseur de puissance. L'unité de commande calcule une valeur de détection de courant électrique de couple et une valeur de détection de courant électrique d'excitation à partir d'un courant électrique circulant vers un dispositif externe et, lorsqu'une valeur absolue de la valeur de détection de courant électrique de couple est supérieure ou égale à la valeur de détection de courant électrique d'excitation, effectue une commande de telle sorte que la valeur de détection de courant électrique d'excitation suive la valeur de détection de courant électrique de couple.
(JA) 電力変換装置は、スイッチング素子を有する電力変換器と、電力変換器を制御する制御部とを有し、制御部は、外部装置に流れる電流からトルク電流検出値および励磁電流検出値を算出し、トルク電流検出値の絶対値が励磁電流検出値以上の場合には、トルク電流検出値に励磁電流検出値が追従するように制御する。
