Capacitors are tiny components that store and release electrical energy in a split second. This video explains how they work, ...

A magnetic resonance imaging method for peering inside capacitors while they are charging and discharging is allowing researchers to scrutinize the ion dynamics that govern the operation and ...

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 ...

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 ...

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.

Pulse-skipping mode (PSM) is widely used as a method for improving the efficiency at light load. For this example, we will use the TPS65290 which has adopted PSM. A simplified block diagram and an ...

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 ...

A research team led by Prof. Hu Weijin from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences (CAS), ...
