Abstract[English]
According to the invention it is provided a power supply system comprising: a DC load having a positive terminal, a negative terminal and an inherent capacitance; a power converter being connected to a grid, and configured to control power supply of the DC load through a DC link; the DC link comprising: a first solid-state circuit breaker comprising a solid-state switch being configured to interrupt power supply from the power converter to the DC load; a first inductor having a first terminal connected to the solid-state switch and a second terminal connected to one of the positive terminal and negative terminal of the DC load; at least one freewheeling diode for providing a current path from the other of the positive terminal and negative terminal of the DC load to the first terminal of the inductor. The invention also relates to a renewable energy power installation and a method.[French]
La présente invention concerne un système d'alimentation électrique comprenant : une charge CC ayant une borne positive, une borne négative et une capacité inhérente; un convertisseur de puissance connecté à un réseau et configuré pour commander l'alimentation électrique de la charge CC par l'intermédiaire d'une liaison CC; la liaison CC comprenant : un premier disjoncteur à semi-conducteurs comprenant un commutateur à semi-conducteurs configuré pour interrompre l'alimentation électrique du convertisseur de puissance vers la charge CC; un premier inducteur ayant une première borne connectée au commutateur à semi-conducteurs et une seconde borne connectée l'une de la borne positive et de la borne négative de la charge CC; au moins une diode de roue libre destinée à fournir un trajet de courant entre l'autre de la borne positive et de la borne négative de la charge CC et la première borne de l'inducteur. L'invention concerne également une installation électrique à énergie renouvelable et un procédé.
