Power Capacitor Symbol. Power capacitors are used to defend different types of equipment from resonance and to develop power quality through absorbing harmonic currents, generated by induction load. These capacitors are available with higher values above 1 Farad. So these can be used in place of a chemical battery.

Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications because they are very efficient in achieving high CV. For example, for case sizes ranging from EIA 1206 (3.2mm x 1.6mm) to an EIA 2924 (7.3mm x 6.1mm), it is quite easy to achieve capacitance ratings from 100μF to 2.2mF, respectively.

There is, in a sense, no qualitative difference. The difference is one of scale, both of current and of time. A bulk capacitor is used to prevent the output of a supply from dropping too far during the periods when current is not available. For line-powered linear supplies, this would occur during the periods (say, 10s of msec) that the line ...

The usable energy in the single string of eight (in series) is W = 1*[(10F/8)/2*((2.7V*8)2-6V2)] = 269.1J Since both capacitor banks store the same total energy, the string with lower voltage has a greater percentage of charge wasted/unusable. In this case, the higher string voltage is preferable to fully utilize the SCs.
