Supercapacitor operates as smoothing capacitor and energy storage device at 50/60 Hz. Possible use of a supercapacitor in compact, low-energy UPS systems.

DC motor voltage (current load of 280mA) from a 50Hz power supply employing first a 2.2 mF electrolytic smoothing capacitor, and then replacing it by a 3 F, 2.7 V PowerStor supercapacitor (see circuit in inset), before and after the interruption of power supply (0 to 75 s). Ripple voltage is shown in the inset… Read More »

Reevaluation of Performance of Electric Double-layer Capacitors from Constant-current Charge/Discharge and Cyclic Voltammetry

In this paper we show the discrepancies between the current frequency- and time-domain analyses (i.e. galvanostatic charge/discharge and cyclic voltammetry) being used for characterizing electric double-layer capacitors, and propose new formulae based on Rs-CPE model. See table below.
