The Grid-Connected Double Stage PV System with SVPWM Cascaded H- Bridge Multi Level Inverter and Current Controller

This research study presents a novel approach to grid-connected photovoltaic (PV) systems using a double-stage configuration. The proposed system uses an advanced current controller that incorporates a PWM technique of Modulation of Space Vector Pulse Width for a Cascaded H-Bridge Multi-Level Inverter. The double-stage architecture enables efficient power conversion and grid integration while ensuring stability and reliability. The Space vector PWM technique optimizes the inverter’s switching patterns, enhancing the system’s performance and reducing harmonic distortion. The current controller provides precise regulation, further improving the system’s dynamic response and grid compatibility. Simulation results show how successful the suggested system is in maximizing solar power utilization, ensuring grid stability, and minimizing harmonic distortion, making it a promising solution for modern grid-connected PV applications.
