Title
(EN) OUTPUT CHOKE ARRANGEMENT FOR INVERTER, AND METHOD IN CONJUNCTION THEREWITH
(FR) AGENCEMENT DE SELF DE SORTIE POUR ONDULEUR, ET PROCEDE ASSOCIE
Abstract
(EN)
A choke arrangement and a method in conjunction with an inverter, the phase output of the inverter being configured to be composed of two or more parallel branches, each of which comprises an upper (V1, V3, V5) and a lower (V2, V4, V6) power semiconductor component at the output, the upper one of which being coupled to a positive voltage of a direct voltage intermediate circuit and the lower to a negative voltage, the components being in series, the output of each branch being composed of a point between the components. The arrangement comprises branch-specific single-phase chokes (L1, L2, L3), the first ends of which chokes are arranged to be coupled to the outputs of the power semiconductor components and the second ends together to form the phase output of the inverter.
(FR)
Cette invention se rapporte à un agencement de self et à un procédé associés à un onduleur, dont la sortie de phase est conçue pour être composée d'au moins deux branches parallèles, comprenant chacune à la sortie des composants semi-conducteurs de courant supérieur (V1, V3, V5) et inférieur (V2, V4, V6), le composant supérieur étant couplé à une tension positive d'un circuit intermédiaire de tension continue et le composant inférieur à une tension négative, les deux composants étant placés en série, et la sortie de chaque branche étant constituée en un point situé entre lesdits composant. Cet agencement comprend des self monophasés spécifiques des branches (L1, L2, L3), dont les premières extrémités sont destinées à être couplées aux sorties des composants semi-conducteurs de courant et les secondes extrémités associées pour former la sortie de phase de l'onduleur.
