Power capacitors: fundamentals of power capacitors
A capacitor is a device that stores energy within an electric field. This is achieved by having two oppositely charged electrical conductors separated by dielectric materials. Power capacitors are constructed of several smaller capacitors, commonly referred to as "elements", "windings" or "packs".
Energy Storage | Applications | Capacitor Guide
Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
