| Abstract | ||||
| This paper is aimed at designing and implementing of control circuits for a stand-alone photovoltaic (PV) LED road lighting system. The main parts of the control circuit are A DC/DC converter and microprocessor control circuit. Control circuit for this system is adjust for Maximum Power Point Tracking (MPPT), which makes the road lighting system operated effectively and adjusts battery charging process. Also, control circuit function is considered to automatically switch lights ON at sunset. The simulation study is done by using the PSIM and Simulation of MATLAB software to achieve good design. Experimental work has been done in the Laboratory of Renewable Energy at Assiut University, Egypt. Experimental results verify the feasibility of this design. | ||||
