应急发电及多电源供电系统设计

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

本设计应用太阳能板与手摇发电机进行发电,利用超级电容进行储电,采用多路DC/DC输出+3.3V、+5V、+12V三种电源。手摇发电过程采用模糊PID算法,实现先恒流再恒压的充电方式,在不改变控制算法的前提下可对1个或多达4个超级电容进行充电;在太阳能充电过程中应用了基于C8051F310的最大功率点跟踪技术。在基于超级电容的供电系统中,采用了基于C8051F310的同步DC/DC技术,从而大大提高了效率。测试结果表明,各项指标均达到设计要求。

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.
