Abstract

L'invention concerne une installation de transfert d'énergie électrique d'une ligne de courant continu (1) à un réseau de tension alternative (5) par l'intermédiaire d'un onduleur à commutation automatique (9), une diode étant associée audit onduleur à commutation automatique (9) côté tension continue. L'invention vise à pouvoir réduire le flux de courant de manière simple en cas d'anomalie dans une telle installation. A cet effet, la diode (8) est câblée avec son sens passant dans la direction du flux d'énergie. Dans un mode de réalisation particulièrement avantageux, la ligne de courant continu (1) est reliée à un réseau d'alimentation en tension alternative (4) par l'intermédiaire d'un redresseur (7) offrant la possibilité d'inverser la polarité de sa tension continue.
