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 ...

Power quality issues involve all aspects of power system operation, from steady-state voltage regulation to the control of high-frequency transients caused by lightning or switching operations.

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, ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

With laptops continuing to slim down in form factor and tablets grabbing larger market shares as time goes on available PCB space is vanishing quickly. To fit into smaller PCB areas, power electronics ...

A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...
