A Multilevel Inverter with Streamlined Components and Reduced THD using the Multicarrier Sine PWM Approach for Resistive and Inductive Loads

In the intriguing realm of power electronics, this paper examines the design process of a revolutionary 129-level inverter, where creativity and imagination meet. This inverter, which embraces the inscrutability of having fewer components and goes beyond harmonic norms, is a paradigm shift in multilevel converter technology. The journey starts with an innovative method that intentionally reduces parts and toggles, challenging the common statement that higher levels require more complexity. As a result, a fascinating symphony of voltage steps smartly rises to $\mathbf{1 2 9}$ levels while simultaneously lowering the Total Harmonic Distortion (THD). The waveform of the inverter mimics a sine wave with unparalleled fidelity, akin to a mystical incantation. A careful control strategy that smoothly switches by Multicarrier Sinusoidal Pulse Width Modulation (MSPWM) technology underpins this amazing performance. In addition to reducing THD, the control mechanism fully utilizes the inverter’s fewer components. This paper reveals not just an inverter but also an enchanted object that surpasses traditional bounds as it invites readers to explore the imaginary world of power electronics. This $129-l e v e l ~ m a r v e l ~ i n v i t e s ~ s c i e n t i s t s, ~$ engineers, and dreamers to set out on an exploration, widening the boundaries of what is imaginable in the magical field of power conversion.
