FPGA-based Implementation of Maximum Power Point Tracking of Solar Cell

Abstract

This article describes the FPGA based implementation of Maximum Power Point Tracking (MPPT) using Perturbation and Observation (P & O) algorithms for solar cell. This work has been organized in two parts. The complete Maximum Power Point Tracking (MPPT) system model was developed in MATLAB/Simulink environment for functionality verification in the first part. It has been observed from the results which show that maximum power is extracted at the load from PV panel. The second part is to design of P & O algorithm from VHDL code. The designed P & O algorithm was synthesized in Xilinx ISE 14.2 software with small commercial FPGA devices i.e. KINTEX-7 and VIRTEX-5. That designed algorithm was simulated using vector waveform file in FPGA tools. Also, the synthesized results were compared on the basis of area-performance-power obtained through summary of both KINTEX-7 and VIRTEX-5 Xilinx FPGA devices. This work is highly beneficial in real time implementation of algorithm for effective performance.
