The invention relates to a power converter comprising several semiconductors (1) and direct voltage and alternating voltage buses (8/9, 4) for electric contact between the direct and alternating voltage connections (3, 2) of the power semiconductors (1). The buses are divided into two parts so that the alternating voltage bus (4) and the direct voltage bus (8/9) do not come into physical contact with each other. One advantage of the invention is that no creepage paths between the direct voltage and alternating voltage buses need to be taken into consideration.
L'invention concerne un convertisseur de courant comportant plusieurs semiconducteurs de puissance (1) et des barres omnibus à tension continue et à tension alternative (8/9, 4) pour assurer le contact électrique de bornes à tension continue et à tension alternative (3, 2) des semiconducteurs de puissance (1). Les barres omnibus sont conçues en deux parties de sorte que la barre omnibus à tension alternative (4) et la barre omnibus à tension continue (8/9) ne soient pas reliées physiquement. De façon avantageuse, aucune ligne de fuite entre les barres omnibus à tension continue et à tension alternative ne doit être prise en considération.
