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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Although advancements in dielectric materials and fabrication processes have improved integrated capacitors, chip designers still depend on board-level devices to support virtually all ICs. Primary ...

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 ...

Technical ceramics are utilized in a variety of products and also for coatings of components that have to be highly wear- or temperature-resistant. They are also used in non-conductive or ...

Regular readers of Hackaday are intimately knowledgeable about old electronics, and whether it’s about that old oscilloscope sitting in the pile of other oscilloscopes, or the very rare vintage ...
