Abstract: It is suggested to build a 9-level pencil-shaped (PS) inverter with a minimum of two DC supplies. Low component multilevel inverters (MLIs) employ extra conducting switches in addition to the DC supply. • This suggested MLI is more effective since it uses fewer power electronic switches. The architecture enables a higher voltage level inverter with a modular design that uses fewer DC supplies and does it appropriately without the need for an additional H-bridge circuit. Additionally, a control plan is suggested for distributing loads equally in a nine-level architecture. • The potential for equitable load distribution in higher-level designs and fundamental frequency switching of switches carrying larger voltage strains are also being looked into. Through simulations and experimental experiments, several notions are validated. The simplified formulae for the suggested inverter parameters are built to determine their optimal capabilities. • Additionally, an optimal PSMLI design is created using the expanded model of the suggested architecture to reduce the inverter's total standing voltage (TSV). Comparison studies are provided to support the proposed inverter and show its benefits over recent MLIs of comparable sorts. • Through accurate simulation and lab tests, the MLI was able to achieve a greater efficiency of 95.54%. The improved 17-level version of PSMLI, on the other hand, achieved IEEE 519 standard performance with total harmonic distortions (THD) of just 5.15%.
