Title
(EN) FILM CAPACITOR WITH BALANCING PATH
(FR) CONDENSATEUR À FILM AVEC TRAJET D'ÉQUILIBRAGE
Abstract
(EN)
A film capacitor (1) includes a first film (2a), a second film (2b), a first electrode (3) a connected to a first terminal, a second electrode (3b) connected to a second terminal, an electrically floating electrode (4), and a balancing path. A part of the electrically floating electrode (4) is in contact with a front side of the first film (2a). The balancing path provides a first balancing connection between the electrically floating electrode (4) and the first terminal and a second balancing connection between the electrically floating electrode (4) and the second terminal. The first balancing connection and the second balancing connection each have an electrical resistance lower than any leakage resistance and higher than 103 Ohm. A leakage resistance is an electrical resistance through any of the first film (2a) and the second film (2b) between the electrically floating electrode (4) and an electrode devoid of contact with the front side of the first film (2a).
(FR)
Condensateur à film (1) comprenant un premier film (2a), un second film (2b), une première électrode (3) connectée à une première borne, une seconde électrode (3b) connectée à une seconde borne, une électrode électriquement flottante (4), et un trajet d'équilibrage. Une partie de l'électrode électriquement flottante (4) est en contact avec un côté avant du premier film (2a). Le trajet d'équilibrage fournit une première connexion d'équilibrage entre l'électrode électriquement flottante (4) et la première borne et une seconde connexion d'équilibrage entre l'électrode électriquement flottante (4) et la seconde borne. La première connexion d'équilibrage et la seconde connexion d'équilibrage ont chacune une résistance électrique inférieure à toute résistance de fuite et supérieure à 103 Ohm. Une résistance de fuite est une résistance électrique à travers l'un quelconque du premier film (2a) et du second film (2b) entre l'électrode électriquement flottante (4) et une électrode dépourvue de contact avec le côté avant du premier film (2a).
