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 ...

Capacitance of a capacitor is defined as the ability of a capacitor to store the maximum electrical charge (Q) in its body. C = Q/V = ε A/d = ε0 εr A/d The ability of a capacitor to store maximum ...

Reliable high-capacity energy storage is one of the major challenges we face in developing new electrical technology. From long-range electric cars to backups for variable-output alternative energy ...

What is a charge pump? A charge pump provides dc-dc voltage conversion using a switch network to charge and discharge two or more capacitors. The basic charge pump switch network toggles between ...

Devices from electric cars to laptops could benefit from a new kind of capacitor, which combines the best features of conventional devices to store a large quantity of charge and release it rapidly.

Various forms of heat pumps—refrigerators, air conditioners, heaters—are estimated to consume about 30 percent of the world's electricity. And that number is almost certain to rise, as heat pumps play ...

As digital still cameras (DSCs) and mobile phone cameras become more popular, users are demanding higher-quality photos under lower-light conditions. The popular Xenon photoflash is excited by high ...

continues his exploration of the technologies which are set to improve the storage of electricity in an era of EVs and increased renewables deployment In our April cover feature, “Charging into the ...
