Supercapacitor (SC), or electric double-layer capacitor (EDLC), technology has matured well during the past two decades into three commercial variations with capacitance values ranging between 1 and 50,000 F. Compared to electrolytic or film-type capacitors with the same canister size, they offer capacitance that is more than 1 million times larger, with a one to two order smaller equivalent series resistance (ESR). A smaller ESR means a very high current charge or discharge capability without excessive heating of the device. One major limitation is the lower dc voltage ratings of less than 5 V.

基于超级电容器的长时间恒定电路:新功率电子电路拓扑的独特设计机会

在过去的二十年中,超级电容器(SC)或双电层电容器(EDLC)的技术已经非常成熟,已经发展成三种商业化的产品,其电容量值在1至50,000 F之间。与具有相同罐的电解或薄膜型电容器相比尺寸,它们提供的电容大于100万倍,等效串联电阻(ESR)小一到二个数量级。较小的ESR意味着在不过度加热器件的情况下具有很高的电流充电或放电能力。一个主要限制是直流额定电压低于5V。
