Les convertisseurs multiniveaux topologies, commandes, application

Abstract

The evolution of powerful semiconductor manufacturing makes such a compromise between the frequency cut-off and power, thus the new technics of inverters switches, which allows to develop a new structures of inverters with great performance unlike the old ones. At first, this memorandum basically concerned with the study of new structures (multilevel power converters).First, we recall the multilevel power converters main advantages and limitation differences, especially the diode topologies closed-loop or electrical condensers on H-Bridge.Evenly, we have presented the so-called hybrid structures which combine the different topologies. Then we have made a theoretical and comparative analysis, simulations of cascade bridge H inteverter on two levels in Matlab/simulink environment.
