Abstract

In this paper, a new single-phase cascaded multilevel inverter is proposed. This structure consists of series connection of proposed basic unit blocks which are built with both unidirectional and bidirectional switches. It can generate only positive Levels at the output. Therefore, an H-bridge is added to the proposed inverter. This inverter is called developed cascaded multilevel inverter. The proposed topology requires lesser number of power switches, drive circuits and dc voltage sources that lead to reduction installation space and cost of the inverter. Thus the simulation has been carried out for various modulation indices using MATLAB/SIMULINK and the results were verified.
