Graphene supercapacitors are moving from lab curiosity to serious contender for the next wave of electric vehicle energy ...

Although SPICE can be a powerful tool, there are pitfalls in relying solely on simulation. To avoid unpleasant surprises, it's imperative that a SPICE simulation be anchored to a detailed ...

Combining the unique strengths of lithium batteries with crazy-fast charging, carbon ultra-capacitors could save a ton of weight and add significant range and power to electric vehicles, according to ...

Although shunt capacitors offer several advantages at all voltage levels, those advantages come at a price. Not only must you purchase, install, and maintain capacitor equipment, you must be able to ...

Editor's note: This article was first featured in the February 2003 issue of EC&M. It has been updated to reflect newer power quality instruments and updated standards. Today, many facilities have ...

Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...
