Abstract

Le but de la présente invention est de faciliter la construction d'un système. Ce système de conversion de courant (100) comprend un premier dispositif de conversion de courant (11), un second dispositif de conversion de courant (12), et un support de câble (2). Le premier dispositif de conversion de courant (11) convertit un courant CA provenant d'un système d'alimentation en courant CC et fournit le courant CC à un bus CC (DB1). Le second dispositif de conversion de courant (12) convertit le courant CC provenant du bus CC (DB1) en courant chargé d'une batterie de stockage (31) comprise dans un corps mobile (3), et fournit le courant chargé converti. Le support de câble (2) soutient un câble (C1). Le câble (C1) est connecté entre le corps mobile (3) et le second dispositif de conversion de courant (12). Le premier dispositif de conversion de courant (11), le second dispositif de conversion de courant (12) et le support de câble (2) sont configurés séparément l'un de l'autre.
