A perennial challenge in power-supply design is the safe and speedy discharge, or “dump,” at turn-off of the large amount of energy stored in the postrectification filter capacitors. This energy, CV 2 ...

Researchers believe they’ve discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging ...

There are many applications which require pulse power. The needed burst of energy is derived by rapidly discharging a previously charged capacitor. As the energy stored in a capacitor is equal to ...

Capacitors are able to charge and discharge more quickly than batteries, and can do so hundreds of thousands of times. Batteries, on the other hand, are able to store more energy than capacitors.

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 ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced CAPZero™-3, the latest ...

We tend to focus on charge storage in terms of the batteries that power our electronic devices and, increasingly, our cars. But charge storage devices now make an appearance on scales ranging from ...

A research team at Washington University in St. Louis has developed a technology that can create a capacitor with 19 times higher energy density than commercially available capacitors. According to ...

Three packs of supercapacitors (in the blue package), consisting of six D-size cells each 18 cells total were able to provide and store the same amount of electrical energy as the smaller pack of six ...

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 ...
