Efficient Single-Phase 15-Level Inverter Design for Enhanced Solar PV Integration

This paper presents an efficient design and implementation of a single-phase 15-level inverter tailored for solar photovoltaic (PV) applications, leveraging MATLAB/Simulink for simulation and analysis. The proposed inverter architecture achieves an elevated level of performance through advanced control strategies and reduced component count. The integration of solar PV systems demands inverters that offer improved power quality, reliability, and energy harvesting. Our design addresses these requirements by employing a sophisticated control algorithm to optimize voltage levels while significantly reducing the number of components, enhancing overall system efficiency and reliability. The MATLAB/Simulink platform is utilized for comprehensive simulation, providing valuable insights into the inverter's behaviour under varying operating conditions. The results demonstrate the effectiveness of the proposed design in terms of output waveform quality, reduced losses, and enhanced energy extraction from solar PV sources, validating its suitability for real-world solar power applications. This research paper contributes to the ongoing efforts to enhance the efficiency and reliability of renewable energy systems, particularly in the context of solar PV integration.
