Abstract:
(EN) Operating defects of an FC converter are detected. A target voltage determination unit (81) determines the output target voltage of a fuel cell (2). A superimposed signal generation unit (82) generates a prescribed reference signal to be superimposed on the output target voltage. A voltage instruction signal generation unit (83) superimposes the reference signal on the output target voltage to generate a voltage instruction signal. A frequency characteristic calculation unit (84) calculates the frequency characteristic of the reference signal component superimposed on the output voltage of the fuel cell (2). An operating defect judgment unit (85) judges that an FC converter (3) has an operating defect if the calculated frequency characteristic is less than a minimum threshold value of an allowed range set based on the reference characteristic. A gain adjustment unit (86) adjusts the gain in the FC converter (3) so that the frequency characteristic calculated by the frequency characteristic calculation unit (84) matches the reference characteristic.
(FR) Les défauts de fonctionnement d'un convertisseur FC sont détectés. Une unité de détermination de tension cible (81) détermine la tension cible de sortie d'une pile à combustible (2). Une unité de génération de signal superposé (82) génère un signal de référence prescrit devant être superposé sur la tension cible de sortie. Une unité de génération de signal d'instruction de tension (83) superpose le signal de référence sur la tension cible de sortie en vue de générer un signal d'instruction de tension. Une unité de calcul de courbe de réponse en fréquence (84) calcule la courbe de réponse en fréquence de la composante du signal de référence superposée sur la tension de sortie de la pile à combustible (2). Une unité d'estimation de défaut de fonctionnement (85) estime qu'un convertisseur FC (3) a un défaut de fonctionnement si la courbe de réponse en fréquence calculée est inférieure à une valeur de seuil minimale d'un ensemble de plages autorisé en se basant sur la caractéristique de référence. Une unité de réglage de gain (86) règle le gain du convertisseur FC (3) de manière à ce que la courbe de réponse en fréquence calculée par l'unité de calcul de courbe de réponse en fréquence (84) corresponde à la caractéristique de référence.
(JA)  FCコンバータの動作不良を検出する。目標電圧決定部81は、燃料電池2の出力目標電圧を決定し、重畳信号生成部82は、出力目標電圧に対して重畳する所定の基準信号を生成し、電圧指令信号生成部83は、出力目標電圧に基準信号を重畳して電圧指令信号を生成し、周波数特性算出部84は、燃料電池2の出力電圧に重畳されている基準信号成分の周波数特性を算出し、動作不良判定部85は、算出された周波数特性が、基準特性に基づいて設定された許容範囲の下限閾値未満である場合に、FCコンバータ3が動作不良であると判定し、ゲイン調節部86は、周波数特性算出部84によって算出される周波数特性が基準特性に合致するように、FCコンバータ3におけるゲインを調節する。
