Abstract :
In this paper, a solar illumination system with three-stage battery charger and dimming control function is proposed. The system structure is divided into two parts. One is three-stage battery charger, which contains PV module, buck-boost converter, charger-discharger controller and lead-acid battery. The other is dimming control of LED module, which contains a 40W LED module, boost converter and controller. Average-current dimming method is used to adjust the luminance of LED module and reduced the power loss of converter. Finally, in this paper, an 80W charger and a 40W LED dimming control is implemented to verify the feasibility of the proposed system.
