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 in ...
Les onduleurs multiniveaux asym´etriques ´etudi´es sont constitu´es de la mise en s´erie de cellules onduleurs de caract´eristiques diff´erentes. Ils permettent d’obtenir une tr`es bonne r´esolution de la tension de sortie. L’alimentation des cellules cons ...
