摘要: Photovoltaic power supplied to the utility grid is gaining more and visibility while world’s powers demand increases. Growing demand, advancements in semiconductor technology magnetic materials such as high frequency inductor cores, has a significant impact on PV inverter topologies their efficiencies, improvement of control circuits potential costs reduction. The user naturally wants operate (PV) array at its highest energy conversion output by continuously utilizing maximum available solar array. electrical system modules are powered arrays requires special design considerations due varying nature generated resulting from unpredictable sudden changes weather conditions which change irradiation level well cell operating temperature. This paper, mathematical model used matlab-simulink environment, developed presented. using basic circuit equations photovoltaic cells including effects temperature changes. main objective find parameters nonlinear I–V equation adjusting curve three points: open circuit, power, short circuit. method finds best for single-diode effect series parallel resistances – Key words : (PV), array,PV
