A New Switch-Diode Cell-Based Single-Phase cascaded Multilevel Inverters

Abstract A novel generalized modular MLI topology blends the unique advantages associated with existing MLIs to enhance the output voltage level incorporating a comparatively lesser number of power electronic components for similar performances. The unique features of the proposed topology pertain to lower distortion as well as total standing voltage (TSV) and best level-switch ratio (LSR) amongst the state-of-art MLIs. Extensive simulations using MATLAB/Simulation platforms as well as experimental models of single-phase 7, 9, 11, 13, 15 level inverter validate the superiority of the proposed topology for pragmatic applications in uninterruptable power supplies, photovoltaic farms, wind farms, and fuel cells.
