Why the Capacitor in Your Power Supply Filter is Too Big

The most common way to implement this filter is to place a large capacitor across the output as shown in Figure 2. This solution is easy and cost effective, but as we will see the filter capacitor stores far more energy than what is actually required for the filtering process. Figure 2.

What Is an Ultracapacitor?

However, capacitors have a very low storage capacity because they store energy in the form of electrons, which repel each other. Ultracapacitors, on the other hand, do not store electrons directly. Instead, they store positively and negatively charged ions and use a liquid electrolyte to facilitate the flow of energy; unlike in batteries, no chemical reactions are
