T.Thamizhselvan Dr.R.Seyezhai Dr.K.Premkumar
Photovoltaic system normally requires maximum power point tracker as its output varies based on solar irradiance and temperature. In order to extract maximum power from PV, a supervised online coactive neuro fuzzy inference system based Maximum Power Point Tracking Technique (MPPT) is proposed in this paper. This MPP controller is executed in a soft switched IBC and it is compared with the conventional P&O and Fuzzy MPPT in terms of maximum power ratio, transient time, overshoot. In order to validate the effectiveness of the proposed MPPT control, two set of operating conditions are taken for analysis such as constant irradiance and step varying irradiance. The overall system is modeled using MATLAB / simulink Toolbox. Finally, the proposed supervised online CANFIS based MPPT is executed using DSP processor and the simulation results are verified experimentally.
