In the contemporary landscape of power electronics, the quest for superior power quality has driven significant advancements in inverter control strategies. This paper investigates the efficacy of Model Predictive Control (MPC) as a sophisticated alternative to traditional pulse-width modulation (PWM) for reducing Total Harmonic Distortion (THD) in multilevel inverters. By leveraging the discrete nature of power converters, MPC facilitates a proactive switching strategy based on future state predictions. Our findings, grounded in both theoretical modeling and empirical literature from regional and international sources, demonstrate that MPC can suppress THD to levels as low as 1.13% in high-level configurations. This performance not only satisfies the stringent requirements of the IEEE 519 standard but also enhances the operational lifespan of grid-connected components.
