2015Abstract
L'invention porte sur un dispositif de commande ou de gestion du fonctionnement de deux moteurs polyphasés et 5 leur alimentation. Le dispositif comporte deux machines électriques à 6 phases couplées en série et alimentées chacune par un onduleur de tension. Cette structure permet ,dans le cadre des applications comprenant deux moteurs devant travailler ensemble mais de façon indépendante, de garantir une tolérance aux pannes (phase ouverte, interrurpteur en court-circuit) avec un nombre réduit de composants de puissance. Ce type de structure suppose un nombre de phases supérieur à 3 pour les machines électriques.
