Development of DC power supply device based on super-capacitors

超级电容器作为一种新型储能器件,具有动态响应好、充放电效率高,免维护等优点,在低压直流系统中具有良好的应用前景。介绍了一种基于超级电容器储能的直流电源装置,主要由主控制单元、充电单元、放电单元、超级电容器储能单元等部分组成,同时,外置的LED显示屏和操作按键便于直流装置的监控和维护。相应的实验结果表明,装置的充电储能速度快,冲击功率的负载能力强,续航能力相对较弱。此外,本装置兼容了输出并联均流功能,既可单独运行,也可多机并联扩大储能容量,为直流系统提供了一种可行的解决方案。

As a new type of energy storage component,super-capacitor was considered to have a promising application in low-voltage DC supply system,for its fast response,high charge-discharge efficiency and low maintenance.A DC power supply device based on super-capacitors was introduced in this paper,which was composed of main control unit,charging unit circuit,discharging unit circuit and super-capacitors energy storage unit.Besides,LED display and poly dome were designed to monitor and control the device.The experiment results show that the device has fast charge-rate,good deep discharge performance,strong impact resistance,but poor battery life.Furthermore,the device was designed to be paralleled to enlarge the energy storage capacity,which could be applied in DC power supply system.
