PV emulator based buck converter using dSPACE controller

This paper proposes the practical realization of a PV emulator based on a buck DC/DC converter. In the beginning we established a theoretical study and a mathematical modeling of the PV model and a simulation of PV emulator based a buck converter under MATLAB-Simulink. A comparative study between results of a real PV panel and the simulated PV emulator are presented. In the next part, we realized the PV emulator controlled by the dSPACE1104 controller board based on a closed-loop reference using a Pulse width PWM modulator. Simulation and experimental results demonstrate that I-V characteristics of the PV emulator and the real PV module are very tightening independently on external weather conditions.
