Multilevel inverters have been newly recognized additional attention in the power engineering. A novel cascaded Z-source Multilevel Inverter (ZS-MI) is promising technique useful for photovoltaic power generation system is presented in this paper. It can defeat the difficulties of conventional photovoltaic power generation system, due to its stabilized DC-link voltage throughout by its boost capability, and also reduction in modules count. In addition, this work investigates all of the operating modes for a module and measures its efficiency. Simulation and experimental results are also given to express the novel features of the proposed scheme for level inverter. © International Science Press.
