A variable frequency drive including a plurality of power cells that are configured as three phases of series-connected cells to deliver power to a load. The drive is operated to increase the output voltage of each power cell using overmodulation.
L'invention porte sur une alimentation à fréquence variable comportant un ensemble de cellules de puissance consistant en trois phases de cellules montées en série, fournissant du courant à une charge. L'onduleur permet d'accroître la tension de sortie de chacune des cellules de puissance en recourant à la surmodulation.
