Abstract

Dispositif de commande de convertisseur comportant un contrôleur, un circuit de détermination des modes et un circuit de conversion de la référence de tension. Le circuit de détermination des modes détermine lequel de trois modes possibles sera utilisé pour contrôler le convertisseur, notamment un mode normal, un mode rectangulaire et un mode de correction nulle, sélectionné en fonction des valeurs et de la polarité des signaux de référence de tension polyphasée. Le circuit de conversion de référence de tension corrige les signaux de référence de tension en fonction du mode sélectionné dans le circuit de détermination des modes. En mode normal, le circuit de détermination des modes produit le signal de référence précédent V~ sans modification à titre de signal de référence de tension nouveau ou corrigé. En mode rectangulaire, le circuit fixe le signal de tension de référence V~ de plus grande valeur parmi les trois phases (phases U, V et W) comme tension de référence minimale (Tmin), laquelle est de polarité opposée à celle du signal de plus grande valeur sélectionné ou, dans une autre version, à une valeur nulle. En outre, le circuit convertit les autres signaux de tension de référence à des signaux de tension de référence corrigés sans changement de la tension de la ligne. Le circuit de contrôle permet de contrôler le convertisseur même en régime de basse tension de référence, qui autrement appartiennent à la région non contrôlée du convertisseur.
