PROJECT TITLE :

An Enhanced Single Phase Step-Up Five-LevelInverter - 2016

ABSTRACT:

During this letter, an enhanced step-up five-level inverter is proposed for photovoltaic systems. Compared with conventional five-level inverters, the proposed topology will notice the multilevel inversion with high step-up output voltage, easy structure, and reduced number of power switches. The operating principle of the proposed inverter has been analyzed and also the output voltage expression has been derived. Likewise, the comparison with existing topologies of single-phase 5-level inverters is presented. Finally, experimental results validate the performance of the proposed topology.
