Abstract

La présente invention concerne une structure parallèle de convertisseurs PWM triphasés à niveaux multiples qui conviennent pour des alimentations électriques distribuées et des systèmes de production électrique reliés au réseau, à base d'énergies renouvelables, pour le chargement et le déchargement, ainsi que le stockage d'énergie. La présente invention comprend plus de deux convertisseurs PWM triphasés à niveaux multiples et des unités de circuit de commande de ceux-ci, un processeur de signal numérique et un circuit d'alimentation en courant alternatif triphasé ; elle comprend en outre un régulateur de tension unifiée commun, le régulateur de tension unifiée étant composé d'un circuit d'échantillonnage de tension, d'un capteur de tension, d'un troisième additionneur et d'un régulateur PI de tension à boucle extérieure, le circuit d'échantillonnage de tension étant monté en parallèle avec une charge RL. Les avantages de la présente invention sont les suivants : le problème de cohérence de la direction de circulation de l'énergie pour chacun des convertisseurs PWM triphasés à niveaux multiples lors d'un fonctionnement en parallèle est résolu, on évite la production d'un courant de boucle et, simultanément, on résout le problème de l'égalité du courant lorsque chacun des convertisseurs PWM triphasés à niveaux multiples fonctionne en parallèle. La présente invention convient pour des scénarios dans lesquels on a besoin d'une conversion électronique d'électricité à haute intensité et échelonnée.
