Abstract[English]
The invention relates to a method of controlling a starting sequence for a power supply device (12), wherein the starting sequence comprises: - activating operating of a thyristor-based converter (22), - activating operating of a first transistor-based converter (24) by keeping a first DC switch (38) in an open status, operating in a capacitive reactive power modus, - activating operating of a second transistor-based converter (26) by keeping a second DC switch (44) in an open status, wherein the second transistor-based converter (26) is operated in an inductive reactive power modus, wherein a second DC voltage is provided at the DC side (42) of the second transistor-based converter, - comparing the increased DC system voltage with the second DC voltage, and, dependent on the comparison, switching the second DC switch in a closed status, stopping providing inductive reactive power and activating a power supply modus of the second transistor-based converter.[French]
L'invention concerne un procédé de commande de séquence de démarrage pour un dispositif d'alimentation électrique (12), la séquence de démarrage consistant à : activer un convertisseur à thyristors (22) ; activer un premier convertisseur à transistors (24) en maintenant un premier commutateur à courant continu (38) dans un état ouvert, le convertisseur fonctionnant dans un mode de puissance réactive capacitive ; activer un second convertisseur à transistors (26) en maintenant un second commutateur à courant continu (44) dans un état ouvert, le second convertisseur à transistors (26) fonctionnant dans un mode de puissance réactive inductive, une seconde tension continue étant fournie au niveau du côté CC (42) du second convertisseur à transistors ; comparer la tension accrue de système à courant continu à la seconde tension continue, et, en fonction de la comparaison, commuter le second commutateur à courant continu vers un état fermé, cesser l'alimentation en puissance réactive inductive et activer un mode d'alimentation électrique du second convertisseur à transistors.
