Alimentation d'onduleurs multiniveaux asymétriques : analyse des possibilités de réalisation et méthodes de répartition de la puissance

The investigated asymmetrical multilevel inverters consist of series-connected inverter cells with different characteristics. They allow to obtain a very good output-voltage resolution. The feeding of the cells is a delicate point which can increase the inverter's complexity and deteriorate its efficiency. This article reviews several solutions to obtain a simple structure with good efficiency.
