The implementation of an efficient FPGA-based digital controller for solar panels

الملخص EN

This paper proposes an FPGA-based implementation of a maximum power point tracking (MPPT) Controller for solar panels.

The proposed architecture is implemented using Field Programmable Gate Array (FPGA) technique, with observance of feature desired as flexibility, and speed without performance loss.

The design have been written in VHSIC Hardware Description Language (VHDL) language, that can be used to accelerate the implementation.

FPGA architecture of MPPT is implemented to overcome the large processing time to obtain maximum power for any environmental condition, during moment to moment variations of light level, shading, temperature, and Photovoltaic (Solar) cell array characteristics.

The implementation of the design is achieved using Xilinx Virtex-II platform as a suitable selected programmable device.

The development of the system software for this work has been done using Active HDL 3.5, and ISE Navigator 6.3 i programs.

Simulation results demonstrating the validity of the proposed algorithm are also reported.
