Abstract
(DE)
Die Erfindung betrifft ein Verfahren und einen Stromrichter (1) zum Steuern einer mehrphasigen elektrischen Maschine (3). Jede Phasenspannung der elektrischen Maschine (3) wird mit zwei zu einer Halbbrücke (5, 6, 7) verschalteten elektronischen Schaltern (9, 10) erzeugt. Die Schaltzustände der Halbbrücken (5, 6, 7) werden mit einer Raumzeigermodulation gesteuert, wobei eine Mindestverweilzeit vorgegeben wird und jeder von einem aktiven Grundspannungsraumzeiger (15, 16, 7) repräsentierte Schaltzustand der Halbbrücken (5, 6, 7) wenigstens für die Mindestverweilzeit beibehalten wird.
(EN)
The invention relates to a method and a converter (1) for controlling a multi-phase electric machine (3). Each phase voltage of the electric machine (3) is generated with two electronic switches (9, 10) interconnected to form a half bridge (5, 6, 7). The switching statuses of the half bridges (5, 6, 7) are controlled with space vector modulation, a minimum dwell time being predefined, and each switching status, represented by an active basic voltage space vector (15, 16, 17), of the half bridges (5, 6, 7) is maintained at least for the minimum dwell time.

L’invention concerne un procédé et un convertisseur de courant (1) pour la commande d’une machine électrique multiphasée (3). Chaque tension de phase de la machine électrique (3) est générée au moyen de deux commutateurs électroniques (9, 10) connectés pour former un demi-pont (5, 6, 7). Les états de commutation des demi-ponts (5, 6, 7) sont contrôlés par une modulation de vecteur spatial, une durée minimale de maintien étant prédéfinie et chacun des états de commutation des demi-ponts (5, 6, 7) représenté par un vecteur spatial de tension de base (15, 16, 7) actif étant maintenu pendant au moins la durée minimale de maintien.
