Analyzing the Performance of a Symmetrical Fifteen-Level Inverter with Component Reduction

This study introduces a novel topology for a 15-level multilevel inverter with the objective of generating a more sinusoidal output voltage while utilizing a reduced number of power-consuming components. In the context of the growing prevalence of renewable energy systems, reliable and efficient power conversion methods are crucial for seamless integration and optimal performance. Multilevel inverters, in comparison to traditional two-level inverters, offer superior power quality, reduced harmonic distortion, and lower voltage stress on power equipment. The proposed topology, employing nine switches and eight DC voltage sources, aims to achieve 15 levels across the load with lower total harmonic distortion (THD). The design incorporates a Phase Disposition Pulse Width Modulation (PDPWM) control technique. Despite the reduced number of switches, this topology demonstrates advantages in achieving higher levels of output voltage.
