Abstract

Un agencement de filtrage sert à filtrer et à atténuer des harmoniques, ainsi qu'à déplacer des points de résonance dans des réseaux électriques. A cet effet, un premier élément amortisseur (Rp21) absorbeur d'énergie est connecté en parallèle à un couplage en série d'une première inductivité (Lp2), d'une première capacité (Cp21) et d'une quatrième capacité (Cp22). Ce couplage en parallèle est connecté en série avec une voie parallèle formée d'une deuxième inductivité (Lp3) et d'une deuxième capacité (Cp3), ainsi qu'avec une troisième capacité (C1). En outre, un deuxième élément amortisseur (Rp41) absorbeur d'énergie est connecté en parallèle avec le couplage en série de la quatrième capacité (Cp22) et de la deuxième capacité (Cp3). L'utilisation de cet agencement de filtrage permet d'amortir très fortement des courants d'harmoniques dans deux fréquences de syntonisation, les fréquences des courants d'harmoniques étant proches d'une de ces fréquences de syntonisation, sans entraîner de pertes significatives dues à des courants ayant la fréquence de service.
