PV Buck Converter Implementation Using Simulink

This document demonstrates the modeling of a PV buck converter using Simulink, a system-level modeling and simulation environment widely employed in power conversion circuit design and performance evaluation. The PV buck converter represents a type of power conversion device used in photovoltaic systems, efficiently converting and utilizing electrical power harvested from solar energy. Simulink's robust capabilities significantly aid in the design and optimization of such buck converters.

Key implementation aspects include using Simulink's electrical component libraries to construct the buck converter topology, implementing PWM control algorithms for switching regulation, and configuring solar cell characteristic blocks to simulate PV panel behavior. The simulation typically involves designing feedback control loops using PID controllers or maximum power point tracking (MPPT) algorithms to optimize energy extraction. Critical functions include power electronics component modeling, system-level simulation parameter configuration, and performance analysis through scope visualization and data logging features.
