Abstract

L'invention concerne un procédé de commande appliqué à un variateur de vitesse (10) de type moyenne tension, ledit variateur de vitesse comprenant plusieurs bras de commutation, chaque bras de commutation comprenant plusieurs cellules de puissance (cellk) connectées en série sur chaque phase de sortie, chaque cellule de puissance comprenant au moins un bus continu d'alimentation sur lequel est appliquée une tension de bus (Vbusk) et un étage de commutation (INVk) commandé par des ordres de commande (Scellk) pour générer une tension de sortie (Vcellk), chaque bras de commutation du variateur fournissant une tension de sortie (Vout) au moteur électrique. Le procédé consiste à estimer la tension de bus (Vbusk) de chaque cellule de puissance (cellk) à partir de la tension de sortie (Vout) acquise pour ladite au moins une phase de sortie et des ordres de commande (Scellk) appliqués audites cellules de puissance pour obtenir ladite tension de sortie mesurée.The invention relates to a control method applied to a medium voltage type speed controller (10), said speed controller comprising several switching arms, each switching arm comprising several power cells (cellk) connected in series on each phase. output, each power cell comprising at least one direct supply bus on which a bus voltage (Vbusk) is applied and a switching stage (INVk) controlled by control commands (Scellk) to generate an output voltage (Vcellk), each switching arm of the drive supplying an output voltage (Vout) to the electric motor. The method consists in estimating the bus voltage (Vbusk) of each power cell (cellk) from the output voltage (Vout) acquired for said at least one output phase and control orders (Scellk) applied to said cells. of power to obtain said measured output voltage.
