Title (EN) POWER CONVERSION DEVICE AND POWER CONVERSION METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE CONVERSION DE PUISSANCE
(JA) 電力変換装置及び電力変換方法
Abstract:
(EN) The present invention is equipped with: a first power conversion device which converts the DC power inputted from an overhead wire through the primary side of an air-core transformer into AC power, and supplies the AC power to an electric motor; a second power conversion device for suppressing a harmonic voltage produced by the first power conversion device; at least one circuit breaker which is connected between the second power conversion device and the secondary side of the air-core transformer; and at least one resistor which is connected in parallel with the circuit breaker between the second power conversion device and the secondary side of the air-core transformer.
(FR) La présente invention est équipée : d'un premier dispositif de conversion de puissance qui convertit l'alimentation en courant continu fournie en entrée par un câble aérien au moyen du côté primaire d'un transformateur à noyau d'air en alimentation en courant alternatif, et fournit l'alimentation en courant alternatif à un moteur électrique ; d'un second dispositif de conversion de puissance pour supprimer une tension harmonique produite par le premier dispositif de conversion de puissance ; d'au moins un disjoncteur qui est connecté entre le deuxième dispositif de conversion de puissance et le côté secondaire du transformateur à noyau d'air ; et d'au moins une résistance qui est connectée en parallèle avec le disjoncteur entre le second dispositif de conversion de puissance et le côté secondaire du transformateur à noyau d'air.
(JA) 架線から空芯トランスの一次側を介して入力される直流電力を交流電力に変換して電動機に供給する第一の電力変換装置と、第一の電力変換装置が発生する高調波電圧を抑制するための第二の電力変換装置と、空芯トランスの二次側と第二の電力変換装置との間に接続された少なくとも1つの遮断器と、空芯トランスの二次側と第二の電力変換装置との間において遮断器と並列に接続された少なくとも一つの抵抗と、を備える。
