Title (EN) CASCADED PACKED U-CELL MULTILEVEL INVERTER
(FR) ONDULEUR MULTINIVEAU À CELLULES EN U ENCAPSULÉES EN CASCADE
Abstract:
(EN) The cascaded packed U-cell multilevel inverter (10) is a power converter for transforming direct current (DC) power to alternating current (AC) power with variable voltage magnitude and variable frequency output. The cascaded packed U-cell multilevel inverter (10) includes a first packed U-cell (PUC) multilevel inverter (12) and at least one sequential packed U-cell multilevel inverter (14) connected in cascade to the first packed U-cell multilevel inverter (12), i.e., the cascaded packed U-cell multilevel inverter (10) is formed by cascading two or more PUC multilevel inverter units (12, 14). Preferably, each PUC multilevel inverter is a 7-level inverter including a DC link capacitor adapted for connection to a separate independent DC power source (22, 24) and a flying capacitor clamping the multilevel inverter to one-third of the voltage of the corresponding power source.
(FR) La présente invention concerne un onduleur multiniveau à cellules en U encapsulées en cascade (10) qui est un transformateur électrique pour transformer une électricité à courant continu (CC) en électricité à courant alternatif (CA) ayant une amplitude de tension variable et une sortie de fréquence variable. L'onduleur multiniveau à cellules en U encapsulées en cascade (10) comprend un premier onduleur multiniveau à cellules en U encapsulées (PUC) (12) et au moins un onduleur multiniveau à cellules en U encapsulées séquentiel (14) connecté en cascade au premier onduleur multiniveau à cellules en U encapsulées (12), c'est-à-dire que l'onduleur multiniveau à cellules en U encapsulées en cascade (10) est formé par agencement en cascade de deux ou plus de deux unités d'onduleur multiniveau PUC (12, 14). De préférence, chaque onduleur multiniveau PUC est un onduleur à 7 niveaux comprenant un condensateur à liaison CC adapté pour connexion à une source d'alimentation CC indépendante séparée (22, 24) et un condensateur volant calant l'onduleur multiniveau à un tiers de la tension de la source d'électricité correspondante.
