Title (EN) VOLTAGE COMPENSATION DEVICE
(FR) DISPOSITIF DE COMPENSATION DE TENSION
(JA) 電圧補償装置
Abstract:
(EN) A voltage compensation device according to an embodiment is provided with: a power converter which includes first to fourth diodes and first to fourth switching elements in a bridge connection; first and second transformers each of which including a primary winding connected in series with a power line, and a secondary winding connected to first and second alternating-current terminals of the power converter; and a control unit which outputs a control signal when a current value of the power line is not less than a threshold value. The control unit, on the basis of the control signal, electrically connects the first and third switching elements to each other, or electrically disconnects the second and fourth switching elements from each other.
(FR) Selon un mode de réalisation, l'invention concerne un dispositif de compensation de tension comprenant : un convertisseur de puissance qui comprend des première à quatrième diodes et des premier à quatrième éléments de commutation dans un montage en pont ; des premier et second transformateurs, chacun comprenant un enroulement primaire monté en série avec une ligne électrique, et un enroulement secondaire connecté à des première et seconde bornes de courant alternatif du convertisseur de puissance ; et une unité de commande qui délivre un signal de commande lorsqu'une valeur de courant de la ligne électrique n'est pas inférieure à une valeur seuil. L'unité de commande, sur la base du signal de commande, connecte électriquement les premier et troisième éléments de commutation l'un à l'autre, ou déconnecte électriquement les deuxième et quatrième éléments de commutation l'un de l'autre.
(JA) 実施形態に係る電圧補償装置は、ブリッジ接続された第1~第4ダイオードおよび第1~第4スイッチング素子を含む電力変換器と、電力線に直列に接続された一次巻線と前記電力変換器の第1~第2交流端子に接続された二次巻線とをそれぞれ有する第1~第2変圧器と、前記電力線の電流値がしきい値以上の場合に制御信号を出力する制御部と、を備える。前記制御部は、前記制御信号にもとづいて、前記第1および前記第3スイッチング素子を導通させ、前記第2および前記第4スイッチング素子を遮断する。
