A new fuzzy-based maximum power point tracker for photovoltaic applications

A new fuzzy maximum power point tracker (mppt) for photovoltaic systems isproposed. fuzzy controller input parameters di dp , ) di dp ( d and variation of duty cycle( dc d ) are used to generate the optimal mppt converter duty cycle, such that solar panelmaximum power is generated under different operating conditions. a photovoltaic systemincluding a solar panel, a fuzzy mpp tracker and a resistive load is designed, simulated andconstructed. the fuzzy mpp tracker includes a buck dc/dc converter, fuzzy controller andinterfacing circuits. theoretical and experimental results are used to indicate the advantagesand limitations of the proposed technique.
