A cascaded converter using hybrid cells and H-bridge structure

This paper introduces a cascaded converter structure using hybrid two-level cells to form single-phase seven-level inverter. Compared various conventional and existing multilevel (MLI) topologies, this topology requires lower number of devices. It uses several DC sources integrated in two-stage provide the required voltage. In topology, DC-link condensers are not necessary. The modes operation modulation proposed described depth. Finally, MATLAB/Simulink platform new is evaluated results reported.
