Energy Storage Using Supercapacitors: How Big is Big Enough?
In a power backup or holdup system, the energy storage medium can make up a significant percentage of the total bill of materials (BOM) cost, and often occupies the most volume. The key to optimizing a solution is a careful selection of components so that holdup times are met, but the system is not overdesigned.
