Design a multilevel inverter with a minimized switch count utilizing a modified H-bridge configuration

Abstract The proposed paper introduces an innovative approach to enhance the efficiency and performance of photovoltaic (PV) systems through the design and investigation of a 15-level multilevel inverter. This inverter topology utilizes a modified H-bridge configuration with 12 switches, aimed at improving voltage control, reducing harmonic distortion, and enabling efficient power conversion. By employing this modified H-bridge architecture, the inverter can achieve 15 distinct voltage levels, which allows for precise control of the output waveform. The design focuses on optimizing the modulation strategy to manage the switching of the 12 switches effectively, minimizing switching losses, and ensuring an efficient energy conversion process. The resulting voltage levels contribute to better output waveform quality and reduced total harmonic distortion. Additionally, the proposed topology is scalable and adaptable, making it suitable for various applications, including grid-connected PV systems, motor drives, and uninterruptible power supplies (UPS). The advantages of the modified H-bridge configuration, such as reduced module count and enhanced controllability, contribute to the practicality and feasibility of the suggested inverter topology. Achieving 15 voltage levels with a limited number of switches underscores its applicability and appeal for renewable energy integration and other relevant power electronics applications. Further experimental validation and real-world implementation are recommended to substantiate the theoretical findings and validate the practical advantages of the proposed inverter topology.
