I continue to be surprised by how many equipment designers are confused by UL circuit protection standards. In trying to meet conflicting standards, engineers may actually decrease the level of ...

For the PDF version of this article, including diagrams and/or equations, click here. In any off-line flyback converter design, it is possible that the output ...

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

Motors and their associated equipment must be protected against both overload and overcurrent (short circuit or ground fault). This function is usually split, with ...

If a motor isn't adequately protected, a short circuit will likely result in premature replacement. Then there's the problem of nuisance tripping upon initial start-up because the magnetic setting of ...

A German research team has developed a semiconductor-based protection concept tailored to renewable energy systems that forces a permanent short circuit in less than 1 millisecond in the event of a ...
