Engineers designing power electronics find that capacitors are needed for several functions, from energy storage to filters and decoupling. Different capacitor types are available, that at first sight ...

Supercapacitors are a special type of electrochemical energy storage device noted for their ability to deliver sudden bursts ...

Capacitors are energy storage devices, consisting of two electrodes and an electrolyte, that are capable of rapid charging and discharging because of charge adsorption and desorption properties at the ...

A capacitor is a passive electronic component that stores electrical energy in an electric field. It consists of two conducting plates separated by an insulating material called a dielectric. When a ...

Switched-capacitor blocks are easily configured to be integrators. When configured as an integrator, a switch-capacitor block can function as an op amp. Closed-loop stability is achieved by ...

A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...

A research group has successfully developed a high-capacity capacitor, an energy storage device -- using a solid electrolyte with high deformability -- that can operate at high temperatures. With this ...
