Abstract: Multilevel voltage source inverter has drawn tremendous importance in the area of high power applications. This paper presents a three-phase modified hybrid cascaded multilevel inverter incorporating a standard three-leg inverter with H-bridge cells in series with each leg. The switching scheme with the multicarrier level shifted sinusoidal PWM is implemented to produce the five-level voltage at the output. Simulations have been performed using MATLAB to study voltage levels, modulation scheme, and THD. Finally, the possibilities of future works are addressed.
