Abstract

L'invention concerne un convertisseur (1) comportant un circuit intermédiaire (3) pour fournir une tension continue (10) entre une ligne plus (11) et une ligne minus (12), une ligne de phase (8, 9) pour recevoir et/ou émettre une tension alternative et un circuit en demi-pont (17) comportant un premier ensemble de commutation (18) pour relier la ligne plus (11) avec la ligne de phase (8, 9) et un second ensemble de commutation (19) pour relier la ligne minus (12) avec la ligne de phase (8, 9). Lors d'un défaut d'un interrupteur à semi-conducteur (20, 21) du convertisseur (1), le convertisseur (1) doit pouvoir s'auto-sécuriser et continuer à fonctionner. A cet effet, le premier ensemble de commutation (18) et le second ensemble de commutation (19) comprennent chacun un circuit parallèle fait de plusieurs branches de commutation (Z) et, dans chaque branche de commutation (Z), l'un des interrupteurs à semi-conducteur (20, 21) est doté de son propre coupe-circuit à fusible (22) connecté en série au trajet de commutation de l'interrupteur à semi-conducteur (20, 21).
