Based on economic, controllability and total harmonic distortion (THD) Multilevel inverters are more rising devices in many applications compare to other traditional inverters. Hence here a novel multilevel inverter (MLI) is designed and analysed with less count of switches and diodes. Generally (L-1) switches are required for conventional L level inverters like flying capacitor, diode clamped, and cascaded multilevel inverters but here a H-bridge inverter with additional two legs having less no of switches is introduced. The converter’s controllability plays a crucial role in enhancing the THD of the output voltage and efficiency. Here a level shifted sinusoidal pulse width modulation technique is implemented i.e Phase Opposition Disposition SPWM (PODSPWM) method, because of it gives better THD over other level shifted SPWM techniques like PDSPWM, APODSPWM,COSPWM,VFSPWM and Phase shift SPWM techniques. The Design and analysis of thisseven level inverter is evaluated with the tool of MATLAB/SIMULINK.
