Design and Implementation of PV MPPT Controller based on Modified P&O Algorithm using FPGA for Satellite Systems

A proposal of Maximum_peak_Power_Tracker (MPPT) controller for photo-voltaic (PV) satellite using Partially modified perturb-and-observe (P&O) technique and FPGA implementation is executed and introduced An enhanced high frequency variable -step -size P&O algorithm is accomplished with fully well programed using a hardware description language (VHDL). Thereafter, an amended MPPT algorithm is implemented on "Spartan-3A/3AN FPGA Starter Kit" FPGA. Simulation and Experimental results are executed and exhibited that the proposed algorithm overcome the disadvantages of the conventional algorithm that can be summarized into tracking speed, reduction of output power oscillation in steady state operation and significant deviation of voltage and power due to sudden change in solar insolation.
