document: Feedforward maximum power point tracking of PV systems using fuzzy controller A feedforward maximum power -LRB- MP -RRB- point tracking scheme is developed for the interleaved dual boost -LRB- IDB -RRB- converter fed photovoltaic -LRB- PV -RRB- system using fuzzy controller . The tracking algorithm changes the duty ratio of the converter such that the solar cell array -LRB- SCA -RRB- voltage equals the voltage corresponding to the MP point at that solar insolation . This is done by the feedforward loop , which generates an error signal by comparing the instantaneous array voltage and reference voltage . The reference voltage for the feedforward loop , corresponding to the MP point , is obtained by an off-line trained neural network . Experimental data is used for off-line training of the neural network , which employs back-propagation algorithm . The proposed fuzzy feedforward peak power tracking effectiveness is demonstrated through the simulation and experimental results , and compared with the conventional proportional plus integral -LRB- PI -RRB- controller based system . Finally , a comparative study of interleaved boost and conventional boost converter for the PV applications is given and their suitability is discussed
