Abstract
A solar power charging system comprising: a voltage converter for converting a voltage level of all original voltage generated by a solar battery into generate a charging voltage and for charging a capacitor by the charging voltage; and a duty ratio control circuit electrically coupled to the voltage converter for supplying a driving clock to the voltage converter for allowing the voltage converter to operate based on the driving clock, wherein the duty ratio control circuit adjusts a duty ratio of the driving clock based on a maximum charge power which depends on the original voltage generated by the solar battery.
