Abstract

L'invention concerne un convertisseur (9), destiné à convertir une grandeur électrique telle que la tension ou le courant dans le domaine du transport et de la distribution de l'énergie électrique, qui présente un montage en série de sous-modules bipolaires (4), qui possèdent chacun un circuit semi-conducteur de puissance et un accumulateur d'énergie, et une structure porteuse (2) destinée à supporter les sous-modules de manière qu'ils soient isolés et juxtaposés en au moins deux rangées superposées (5, 6, 7). Il est prévu un rail (8) de liaison électrique entre les sous-modules (4). Afin de fournir un convertisseur aussi compact et aussi économique que possible tout en assurant une résistance suffisante à la tension, il est proposé qu'un sous-module (524) disposé sur le bord extérieur d'une première rangée (5) soit relié à un sous-module (61) de la deuxième rangée disposée au-dessus ou au-dessous, ce dernier étant disposé sur un deuxième bord extérieur de la deuxième rangée (6) opposé au premier bord de la première rangée (5).
