Implementation of a MPPT fuzzy controller for photovoltaic systems on FPGA circuit

Maximum power point tracking (MPPT) must usually be integrated with photovoltaic (PV) power systems so that the photovoltaic arrays are able to deliver the maximum power available. The present paper proposes a maximum power point tracker (MPPT) method, based on fuzzy logic controller (FLC), applied to a stand-alone photovoltaic system under variable temperature and irradiance conditions. The objective of this controller is to extract the maximum power of photovoltaic modules. The main objective of this work is the development of this control and its implementation on a "FPGA Xilinx Virtex-II" circuit using "Memec Design Virtex-II V2MB1000" Development Board. Thus, we can show the advantages of using the FPGA circuits, which are their short development time, their low cost and their flexibility of operation.
