    27- Level High Frequency Transformer Based- MLI for Integration of Renewable Energy

    By M. Krishna, P. Ajay D, Vimal Raj

    Abstract: This research proposes a unique high-frequency transformer (HFT)-based multilevel inverter(MLI) with 27 levels can be constructed with a single DCpower supply and twenty switching devices. The proposedMLI topology comprises three medium frequency isolationtransformers, each with a different rated voltage. Since thetransformers used in MLI operate at high frequencies, thesuggested system has a smaller volume and weight. Acascaded H-bridge (CHB) connects each transformer'sprimary windings, and the secondary windings areconnected in series …

    Reduced Switch Seven-Level Multilevel Inverter for Renewable Energy Applications

    By M. Krishna, Botta Kusuma Kumari, A.S.V. Vijaya Lakshmi

    Abstract: The world is currently dealing with two majorissues. The first issue is a shortage of fossil fuels in the nearfuture, and the second is increased atmospheric pollution,which leads to an increase in ambient temperature (globalwarming), which necessitates the need to switch fromtraditional energy sources to renewable energy sources (RES).As the power generation from renewable energy sources isincreasing gradually, the importance of multilevel inverters isalso rising day by day for the …
