Analysis of Maximum Power Point Converter Topologies of Photovoltaic System Using Incremental Conductance Control

The maximum power that could be generated by a Photovoltaic System is depending on temperature and irradiance variations. The maximum power increases as the irradiance increases and vice versa. While, maximum power decreases as the temperature increases. In order to obtain fully utilization from the PV array, an algorithm of Maximum Power Point Tracking (MPPT) functions with a high efficiency of dc/dc converter is necessary. In this paper, it is presented Incremental conductance method to obtain maximum power from solar panel. The solar panel is studied and incremental conductance method is analyzed. This paper also presents another method for maximum power point tracking which includes sensor circuit, differentiator and Zero crossing detector. The output of zero crossing detector is observed using Matlab Simulation.
