Enhancing Grid Connectivity with a Double-Stage PV System

This research work focuses on the proper utilization of electricity from a photovoltaic (PV) system with a grid connection. There are no issues when the PV system and grid are connected appropriately. However, any mismatch between them can lead to severe problems. The project aims to address these challenges by employing a multilevel inverter and LC filters to ensure a proper connection between the grid and the PV system. Additionally, the project uses a boost converter to enhance the efficiency of the DC output voltage from the PV modules. Furthermore, the application of sinusoidal PWM techniques to the inverter is expected to yield efficient results.
