FPGA Based Maximum Power Point Tracking of Photovoltaic System Using Perturb and Observe Method During Shading Condition

Nowadays, PV cell which is known as a photovoltaic is one of the most important parts in electrical field to convert photo light to voltage and current at the desired output voltage and frequency by using varies control techniques. This project presents design and implementation of FPGA Based Maximum Power Point Tracking (MPPT) Controller for Photovoltaic system using Perturb and Observed method (P&O). The MPPT controller is employed to control and get Maximum Power Point (MPP) from the source. Altera DE1 board is used as a controller for the implementation of the MPPT system. The simulation of this FPGA based MPPT controller is designed and implemented using Quartus II VHDL software tools. The results shown, the same signal obtained from Mat lab simulink software as compared with Quartus II. It has been observed that the designed system has been successfully extracting the MPP during partially shading condition as in the simulations.
