PERFORMANCE ANALYSIS OF A SINGLE-STAGE SOLAR INVERTER WITH INTEGRATED BOOSTING TECHNIQUE

Abstract

The intention of this study is to examine a single-stage solar inverter that integrates boosting to improve the efficiency of energy conversion and the compactness of the system. The concept that has been proposed eliminates the necessity for a DC–DC boost converter by enhancing the voltage at the inverter stage. In addition, the overall system cost, switching inefficiencies, and the number of components are all reduced. The conversion efficiency, power quality, total harmonic distortion (THD), and voltage gain are all subjected to rigorous testing under a diverse range of solar irradiation and load conditions. The integrated control system not only improves dynamic responsiveness and MPPT efficiency, but also improves stability. Simulators and experiments have demonstrated that the inverter that has been introduced is superior to two-stage systems in terms of energy losses, voltage management, and efficiency, rendering it appropriate for use in modern solar applications.
