It takes a cheap ATMGA16 as the intelligent controller. The proposed energy management controller effectively enhances the system performance. The controller uses the maximum power point tracking (MMPT) scheme to precisely control the battery charge. Automatic switching between battery and utility provides power supply of the lighting system. According to the actual intensity of the sun, the controller and TPS61042 accurately control the LED brightness. The experimental results show that the system controls accurately, conversion efficiency is high, and it works stably.
