Abstract
The present disclosure provides an adaptive solar energy harvesting device comprising a solar energy receiving unit, a voltage converter and a charging power controller. The voltage converter has an input terminal and an output terminal. The input terminal of the voltage converter is coupled to the solar energy receiving unit, and receives the electric energy generated by the solar energy receiving unit through the input terminal. The charging power controller is coupled to the output terminal of the voltage converter, and senses the supply voltage at the output terminal of the voltage converter. The charging power controller generates a charging voltage and a charging current to charge at least an electricity storage unit. The charging power controller adjusts the charging voltage and the charging current according the feed-forward control related to the supply voltage at the output terminal of the voltage converter.
