The paper has introduced a cost effective design of supercapacitor for satellite applications.
Supercapacitors, also known as ultracapacitors and electric double layer capacitors (EDLC), are capacitors with capacitance values greater than any other capacitor type available today. Supercapacitors are breakthrough energy storage and delivery devices that offer millions of times more capacitance than traditional capacitors.
In addition, supercapacitor applications vary widely from high peak current/power uses to lower current/longer duration applications. This variety of needs is addressed by the test specifications and parameter requirements defined in IEC/EN 62391–1, Fixed electric double layer capacitors for use in electronic equipment.
The supercapacitor is a type of capacitor that has capacitance values extremely higher than the conventional electrolyte capacitors. However, from the construction and operation points of view, the supercapacitor and electrolyte capacitor differ, significantly. The structure of the supercapacitor is shown in Fig. 4 (a).
The supercapacitor can be modeled as several capacitors connected in parallel each with an increasing value of series resistance. The capacitors with low values of series resistance charge quickly thus increasing the terminal voltage to the same level as the charge voltage.
If a series resistor is used, ensure that the voltage outputs of the supercapacitor are connected directly to the application and not through the resistor, otherwise the low impedance of the supercapacitor will be nullified. Many battery systems exhibit decreased lifetime when exposed to high current discharge pulses.
