| 摘 要： | 在储能电容器中,双电层电容器的储能密度特别高,但其内电阻大,且元件的输出电压低。笔者对双电层电容器的单元结构进行了改进,电气性能有了明显地提高,元件电压可达400 V(0.7 F)、储能密度达4 J/cm3,经试验测得其内电阻较小,可以满足大电流放电的要求。提出了一种电路拓扑解决电容器的极性问题,使之能够进行交流放电,从而拓宽了它的应用领域。

| Abstract: | Electric double-layer capacitors (EDLC) exhibit very high storage energy density compared with other capacitors, but their inner resistance is rather higher and output voltage lower. Based on EDLCs, some improvements have been made for increasing operation voltage, which led to an operation voltage of 400 V (0.7 F), and a storage energy density of 4J/cm3. The measured inner resistance of the capacitors is low enough to meet the requirement of large current discharge. A circuit topology was designed to solve the polarity problem with the capacitors for alternate current applications. |
