Boost Inverter Using Sliding Mode Controller for Photovoltaic Applications

Abstract

This research paper presents an enhanced power conversion strategy for photovoltaic systems through the application of a sliding mode controller for a boost inverter circuit comprising four IGBT switches. The proposed system seeks to capitalize on the inherent advantages of boost inverters, such as high power density and efficiency, while addressing the dynamic challenges posed by PV systems. The integration of the SMC aims to harness its robustness against system uncertainties and external disturbances, ensuring optimal performance in power conversion. In a comparative evaluation, the conventional PID controller was also implemented for benchmarking purposes. Through rigorous simulation studies, it was determined that the SMC consistently outperformed the PID controller, offering superior regulation, faster transient response, and lower output voltage distortion in the face of varying solar irradiances and load conditions. The simulation results validate the potential of the SMC-equipped boost inverter, marking a substantial improvement over traditional PID-based systems in terms of reliability and efficiency for photovoltaic applications. This investigation underscores the efficacy of sliding mode control as a promising alternative for advancing the state of PV energy conversion systems.
