SUPERCAPACITORS
[attachment=16676]
Introduction
In power electronics, Electrical Energy Storage(EES) refers to the process of converting electrical energy from power into an electrical or non-electrical form that can be stored for converting back into electrical energy as per requirement.
This process enables electricity to be produced at time of either low demand, low generation cost and used at times of high demand, high generation cost or unavailability of other generation scheme.
What is Supercapacitors?
are the electrochemical storage devices, storing electricity in the form of Electrochemical double layer.
dfferent from batteries or dielectric capacitors or parallel plate condensors (electricity is stored electrostatically in a dielectric material between two metal plates).
Application Areas :
Short term support for uninterrupted power system with generator backup.
Computer memory backups- low-current, long-duration requirements.
At sharp turns on electric traction.
Quick charge applications- charging in seconds and discharging in minutes(for power tools and toys)
Electric vehicles(starting and regenerative breaking)
In solar array applications.
