Design of multi-power source power supply system and emergency electricity generation

In the design,the solar panels and the hand generator were used to generate electricity,and a super capacitor was used to store energy,multiple DC/DC was used to output ＋3.3 V,＋5 V,＋12 V power supply.In the hand generation process,the fuzzy PID algorithm was used to achieve first-constant-current-and-end-constant-voltage charging method,which could premise one or as many as four super capacitors without changing the control algorithm.In the application of solar,the maximum power point tracking technology based on C8051F310 was adopted.In super capacitor power supply system,synchronous DC/DC technology was used to improve efficiency substantially.The results showed that the indicators could meet the design requirements.
