NOVEL REDUCED-COMPONENT MULTILEVEL INVERTER FOR STANDALONE SOLAR ENERGY CONVERSION SYSTEMS

The goals of this research are to increase system reliability, decrease power losses, and save costs in standalone photovoltaic (PV) applications by researching and developing an efficient inverter with fewer components. The use of several switches and passive components in traditional inverter designs reduces efficiency and increases complexity. The suggested inverter is well-suited for use in off-grid environments because it uses efficient control algorithms and a simplified power circuit to transform direct current (DC) electricity from a solar source into high-quality alternating current (AC). Using a Maximum Power Point Tracking (MPPT) algorithm, the architecture is built to work efficiently in different sun irradiation and load scenarios, enhancing energy extraction from the photovoltaic array. Without the need for complex filters, a diminished-switch multilevel design is used to enhance the quality of voltage waveforms and maintain low Total Harmonic Distortion (THD). Based on the findings of the MATLAB/Simulink simulations, the inverter is a great choice for small and affordable standalone solar systems because of its constant performance, low conduction and switching losses, and high efficiency.
