Design and simulation of closed loop proportional integral (PI)‎ controlled boost converter and 3-phase inverter for photovoltaic (PV)‎ applications

Abstract EN

This research deals with the design and simulation of a solar power system consisting of a KC200GT solar panel, a closed loop boost converter and a three phase inverter by using Matlab / Simulink.

The mathematical equations of the solar panel design are presented.

The electrical characteristics of the panel are tested at the values of 1000 W/m for light radiation and 25 °C for temperature environment.

The Proportional Integral (PI) controller is connected as feedback with the Boost converter to obtain a stable output voltage by reducing the oscillations in the voltage to charge a battery connected to the output of the converter.

Two methods (Particle Swarm Optimization (PSO) and Zeigler- Nichols) are used for tuning PI controller to enhance the overall performance of the system.

The Sine Pulse Width Modulation (SPWM) technique was used to obtain a pure 3-phase in low distortion.

The voltage and current output values of ± 14V and ± 2.8A are obtained, and the Total Harmonic Distortion (THD) value is 4.20%.
