In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

Circuit Playground: C is for Capacitor

A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store energy electrostatically in an electric field. The forms of practical capacitors vary widely, but all contain at least two electrical conductors (plates) separated by a dielectric (i.e., insulator ). The conductors can be thin films of ...

DC link, energy storage, and pulse power capacitors

A DC link is typically connected to a rectifier (or other DC source such as a battery) and an inverter. A DC link capacitor is used as a load-balancing energy storage device. This capacitor is connected in parallel between the positive and the negative rails and helps prevent the transients on the load side from going back to the input side.
