Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

Within the body of a high-voltage multi-layer ceramic capacitor, a gap-type defect is beginning its career of destruction. The defect may be a void within the ceramic dielectric, a crack within the ...

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 ...

Virtually every type of electronic hardware incorporates capacitors, which are widely used for functions such as bypassing, coupling, filtering, and tunneling electronic circuits. However, to be ...

In residential and light commercial HVACR, we work with run capacitors every day, and you may have noticed that they fail quite often. Because of this, many companies are beginning to integrate ...

TORONTO, ONTARIO--(Marketwired - Aug 12, 2015) - EEStor Corporation (TSX VENTURE:ESU) ("EEStor" or the "Company"), today announced the findings of the independent Phase 3 testing conducted by Intertek ...

A few years ago, after more than 25 years of working with these things, I learned something new about ceramic capacitors. I was working on an LED light-bulb driver and the time constant of an RC ...
