The method relates to the operation of a frequency converter of a generator in particular of a wind energy turbine, in the event of a substantial grid voltage drop, wherein the frequency converter (10) comprises an AC/DC converter (20), to be connected to the generator (14), a DC/AC converter (22) to be connected to the voltage grid (18), and a DC link circuit (24) for connecting the AC/DC converter (20) to the DC/AC converter (22). The method comprises the step of reducing an output voltage of the DC link circuit (24) for increasing an output current of the DC/AC converter (22) and/or reducing the operation frequency of electronic switches (28) of the DC/AC converter (22) for increasing the output current of the DC/AC converter (22).

L'invention concerne un procédé de fonctionnement d'un convertisseur de fréquences d'un générateur, notamment, dans une turbine d'énergie éolienne, en cas d'une baisse de tension de grille importante. Ledit convertisseur de fréquences (10) comprend un convertisseur c.a./c.c (20) à connecter au générateur (14), un convertisseur c.c./c.a. (22) à connecter à la grille de tension (18) et un circuit de connexion c.c. (24) servant à connecter le convertisseur c.a./c.c (20) au convertisseur c.c./c.a. (22). Ledit procédé consiste à diminuer une tension de sortie du circuit de connexion c.c. (24) de manière à augmenter un courant de sortie du convertisseur c.c./c.a. (22) et/ou à diminuer la fréquence de fonctionnement de commutateurs électroniques (28) du convertisseur c.c./c.a. (22) afin d'accroître le courant de sortie du convertisseur c.c./c.a. (22).
