| 摘要: |
| 为解决现有配电自动化终端电源存在使用寿命短及维护困难的问题，提出了一种基于超级电容器（SC）的智能直流不间断电源方案。采用升压变换器降低超级电容器的工作电压，从而提高电容器储能的利用率，延长失电情况下电源的待机工作时间；根据超级电容器最小工作电压与剩余能量的关系，确定了超级电容器最小有效工作电压；根据变换器的期望输出功率、失电待机时间及超级电容器的最小工作电压，确定了超级电容器容量；通过对升压变换器最大输出纹波电压进行分析，对其电感及输出滤波电容的进行了优化设计。实验结果验证了所提方案的可行性。 |

| Abstract: |
| Aiming at the short service life and difficult maintenance of DC power-supply of power distribution automation terminals，a scheme of intelligent DC uninterrupted power-supply based on SC（Super-Capacitor） is put forward. The Boost converter is used to reduce the operating voltage of SC for raising the utilization rate of its energy storage to extend the standby time in case of power loss. The minimum operating voltage of SC is determined according to the relationship between its minimum operating voltage and its residual energy，while its capacity is determined according to the expected output power of Boost converter，the standby time and the minimum operating voltage of SC. The maximum output ripple voltage of the Boost converter is analyzed and its inductor and the capacitor of output filter are optimally designed. The experimental results verify the feasibility of the proposed scheme. |
