PV Based Multilevel Inverter Using Reduced Number of Switches with Modified H-Bridge

The proposed paper presents an innovative approach to enhance the efficiency and performance of photovoltaic (PV) systems through the design and analysis of a 15-level multilevel inverter. The proposed inverter topology employs a modified H-bridge configuration utilizing 12 switches, aimed at improving voltage control, reducing harmonic distortion, and enabling efficient power conversion. The modified H-bridge architecture allows for achieving 15 distinct voltage levels, enabling precise control of the output waveform. The design emphasizes optimizing the modulation strategy to effectively 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. Furthermore, the proposed topology offers scalability and adaptability, making it suitable for a wide range of applications, including grid-connected PV systems, motor drives, and uninterruptible power supplies. The advantages of the modified H-bridge configuration, in terms of reduced component count and enhanced controllability, contribute to the practicality and feasibility of the proposed inverter topology. The design's ability to achieve 15 voltage levels while employing a limited number of switches highlights 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.
