Driving capacitive loads at speed is difficult. The fundamental reason for this is that the current charging due to the voltage change is limited only by the equivalent series resistance (ESR), which ...

Here's how to reduce the effect of capacitor switching on your power system Last month's article discussed exactly what happens when electric utilities switch shunt capacitors: power system components ...

Restrikes or re-ignitions occur when the dielectric strength of the open gap, during contact parting, is not great enough to withstand the recovery voltage across the open gap. With a capacitive load, ...

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 ...

This article is dedicated to Jim Williams who several years ago (2006) wrote an article in EDN regarding the need of a good lab apparatus to qualify the behavior of voltage regulators for compliance ...
