Implementation of FPGA control for multilevel boost converter used for PV applications

This paper presents the implementation of a Maximum Power Point Tracker (MPPT) for photovoltaic (PV) applications by using multilevel boost converter and FPGA Board. The control algorithm for extracting maximum power from the cell is proposed by means of the VHDL code and implemented using Xilinx XC3S400 FPGA Board. In this work, a practical implementation of the real-time Estimate Perturb and Absorb algorithm for maximum power point tracking (MPPT) control in a PV system has been developed. The Developed implementation has the advantage of simple programming with high performance even with low resolution ADC and low cost current sensor. The proposed technique has been validated through detailed experimental work.
