Manjunathachari Journal on Electronics Engineering 2249 – 0760 5 4 31 37 Photovoltaic System, Controller, PWM, Maximum Power Point Tracking, Physical To Real Time Interface The manufacturing and utilization of photovoltaic arrays have advanced dramatically in the recent years. The use of new, efficient Photovoltaic Solar Cells (PVSCs) has emerged as an alternative measure of renewable green power, energy conservation and demand side management. Maximum Power Point Tracking (MPPT) techniques are employed in photovoltaic (PV) systems to make full utilization of PV array output which depends on solar irradiation and temperature. These techniques vary in many aspects as range of effectiveness, hardware, sensor required and cost. This paper presents an optimized controller design which increases the conversion efficiency of a photovoltaic system under variable temperature and irradiance conditions. It also includes the comparison of the efficiency of the PV system by incorporating the controller circuit on the existing MPPT algorithms in real time and in simulation. Different development stages are presented and then the optimized controller is simulated and evaluated which has shown better performances. Matlab Simulink tools have been used for performance evaluation on energy point. Simulation will consider different solar irradiance and temperature variations. The real time model produced includes rotating the panel under uniform and non uniform shaded conditions which is driven by a brush motor. June – August 2015 Copyright © 2015 i-manager publications.
