As semiconductor manufacturers introduce new wireline transmission devices built on smaller CMOS geometries, more circuit protection challenges are emerging. This article explores five frequently ...

The analysis of magnitudes and durations of touch voltages in cable installations can provide electrical professionals with a better understanding of the requirements of Art. 250 of the NEC regarding ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...
