FPGA-in-the-Loop Implementation of a Grid-Connected Inverter for Renewable Energy Systems
Youness HAKAM, Mohamed LAMANE, Mohamed TABAA
Abstract. This paper presents the modeling, control, and FPGA in the loop (FIL) validation of a grid-connected inverter designed for renewable energy integration. The inverter converts DC power from photovoltaic or fuel cell sources into AC power while maintaining synchronization with the utility grid. A real-time control algorithm based on PID controller is implemented using MATLAB/Simulink and executed on an FPGA to achieve fast dynamic response and precise current control. The FIL platform enables hardware-level verification of the control strategy, ensuring system stability and reduced total harmonic distortion (THD). Simulation and experimental results confirm the inverter’s high efficiency, accurate grid synchronization, and suitability for smart grid and distributed generation applications.
