Abstract

L'invention concerne une installation électrique dotée d'un convertisseur matriciel (MU) et un procédé permettant de la faire fonctionner. Le convertisseur matriciel (MU) comporte plusieurs bornes d'entrée (E1, E2, E3), plusieurs bornes de sortie (A1, A2, A3) et plusieurs convertisseurs partiels, les bornes d'entrée (E1, E2, E3) étant reliées respectivement par l'intermédiaire de commutateurs bidirectionnels des convertisseurs partiels aux bornes de sortie (A1, A2, A3). Au moins une source de tension continue (1, 2) est connectée aux bornes d'entrée (E1, E2, E3) par l'intermédiaire d'un convertisseur (S). Parmi les tensions simples appliquées sur les bornes d'entrée (E1, E2, E3), la tension simple présentant la valeur respectivement maximale est commutée sur le pôle plus (P) du convertisseur (S) et la tension simple présentant la valeur respectivement minimale est commutée sur le pôle moins (M) du convertisseur.
