The capacitor auto-discharge module presented in this article is simply a failsafe module that automatically discharges the buffer/filter capacitor in a power supply circuit when its input supply is ...

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 ...

Your phone died. Again. In these scenarios, who among us has not dreamed the dream of a future where our devices charge instantly and last forever. As capacitors—or even more exciting, ultracapacitors ...

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.

Pseudocapacitors are a type of electrochemical energy storage device that combines the high energy density of batteries with the fast charge/discharge rates and long cycle life of capacitors. They ...

Jamicon has introduced the DA series of supercapacitors, available in the UK from specialist components distributor Components Bureau. Bridging the gap between capacitors and batteries, these electric ...

A capacitor charging power supply has two power ratings expressed in Joules per second (J/s), the peak power and the average power. The peak power rating is used when calculating the charge time, and ...
