This paper presents a multilevel inverter which includes DC-DC Z-source converter that is connected through DC link to multilevel cascaded H-bridge inverter. In order to provide several isolated input DC sources required for H-Bridge structure, Z-source DC-DC converter is applied which also have the ability to boost the input. Operation principles, configuration, and the relations for steady state operation of the converter are described in detail. Simulation of proposed topology is carried out using MATLAB/Simulink and the results are included in the paper. The proposed module is used to converts input voltage of 25 Vdc from Photovoltaic (PV) panels to 333 V ac in CCM to verify the effectiveness of the theoretical analysis.
