Sažetak
A Mutual Inductive Coupled (MIC) DC-DC power converter circuit for Photo-Voltaic (PV) system employing fuzzy logic based maximum power point tracking is presented in this research paper. The proposed DC-DC converter has been modelled and simulated using Matlab-simulink environment for obtaining high gain. The mutually coupled inductor uses one core instead of two or more, which reduces size of the converter. A passive regenerative snubber is exploited for absorbing the energy of stray inductance and also the capacitors are charged in parallel and discharged in series through the mutual coupled inductor for achieving high voltage gain of this converter. The voltage gain characteristics of the MIC converter have been studied for various coupling coefficient, turns ratio of two-winding mutual inductor and duty cycle. Moreover, PV system is conveniently interfaced with proposed power converter for maximizing the solar energy yield and analysed by employing Perturb & Observe (P&O) and fuzzy logic based MPPT algorithms under various operating conditions. The obtained results reveal that, the fuzzy controller provides good improvement in tracking of maximum power and helps to extract considerable amount of additional solar energy from a PV module as compared with P&O algorithm.
