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