In this thesis, the design and implementation of a stand-alone solar power lighting system are the study objectives. The system architecture includes solar cells, high power-light emitting diodes (HP-LED) modules, bi-directional buck-boost DC converters, lead-acid battery and a single-chip microcontroller. Its main circuit is a bi-directional buck-boost DC converter, combining a single-chip microcontroller to manage and control both of charging and discharging functions. The system has maximum power point tracking control, pulse charging control and high power-light emitting diodes driving control functions. Finally, through computer simulation and experimental measurement, this design has been verified.
