【摘要】 设计了一个利用法拉级超级电容器作为储能元件的供电系统。该系统由充电装置和直流稳压器两部分构成,充电装置可以在数分钟内将超级电容器充满电,直流稳压器为用电设备提供了不同幅值的直流恒定电压。提出了恒流充电与恒压充电相结合的充电方式,缩短了充电时间。实验结果表明,该系统可以作为传统蓄电池的一种替代品,其突出优势是大大缩短了充电所用的时间。更多还原

【Abstract】 A new power source system which uses supercapacitors as the energy storage element was designed. The system is made up of charging device and DC-DC converter. The charging circuit charged the supercapacitors in a few minutes and the DC-DC converter provided the sensors with different constant voltage values. The constant-current charging and the constant-voltage charging were combined. The experiment results show that our system is a good replacement of conventional batteries.更多还原
