Simulation of Transformer less Eleven Level Converter Connected to Grid and PV Systems

Ala Praveen Kumar, L.Veera Kotlu


Photovoltaic energy is a wide kind of green energy. A high performance on these systems is needed to make the most of energy produced by solar cells. Also, there must be a constant adaptation due to the continuous variation of power production. The switching strategy is employed such that to regulate the flying-capacitor voltage, improves the efficiency for most devices switch at the frequency and will minimize the minimum the common-mode leakage current with the help of a novel dedicated circuit. Simulation results confirm the feasibility and good performance of the proposed converter.
