An Intelligent Driving and Management System of Solar LED with Adaptive Disturbance Observation Method

摘要

Solar power has become one of the most important renewable resources due to the energy crisis recently. An intelligent solar LED lighting driver system based on embedded technology was designed to make full use of the green energy. Electricity which was detected real-timely was generated by solar cells. Boost-Buck DC/DC converter was controlled by PWM to realize the control of Maximum Power Point Tracking Charge and the intelligent management to the batteries. Besides, LED was adopted to improve the energy efficiency, working reliability, practicality and environment protection. The new system is efficient, stable and practical. It can be widely applied in all kinds of embedded devices to supply the effective and environment protective energy.
