The purpose of the present disclosure is to facilitate the construction of a system. This power conversion system (100) comprises a first power conversion device (11), a second power conversion device (12), and a cable support (2). The first power conversion device (11) converts AC power from a power system (4) into DC power and outputs the DC power to a DC bus (DB1). The second power conversion device (12) converts the DC power from the DC bus (DB1) into charged power of a storage battery (31) included in a moving body (3), and outputs the converted charged power. The cable support (2) supports a cable (C1). The cable (C1) is connected between the moving body (3) and the second power conversion device (12). The first power conversion device (11), the second power conversion device (12), and the cable support (2) are configured separately from each other. 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. 本開示の課題は、システムの施工をしやすくすることである。電力変換システム（１００）は、第１電力変換装置（１１）と、第２電力変換装置（１２）と、ケーブル支持器（２）と、を備える。第１電力変換装置（１１）は、電力系統（４）からの交流電力を直流電力に変換して直流バス（ＤＢ１）に出力する。第２電力変換装置（１２）は、直流バス（ＤＢ１）からの直流電力を移動体（３）の有する蓄電池（３１）の充電電力に変換して出力する。ケーブル支持器（２）は、ケーブル（Ｃ１）を支持する。ケーブル（Ｃ１）は、移動体（３）と第２電力変換装置（１２）との間に接続されている。第１電力変換装置（１１）、第２電力変換装置（１２）、及びケーブル支持器（２）は、互いに別体に構成されている。
