Voltage clamps for protecting low-voltage dc circuits require a new approach to circuit design. Many commonly used voltage clamps were built for systems of 5 V or higher, but lower-voltage systems ...

Management and maintenance personnel at power generating facilities face the same challenges operating their plant’s electrical distribution system as other large industrial plants-shrinking resources ...

Editor’s note: This article is based upon a 2006 EDN article by Jim Williams; see Reference 1. There are six different types of FETs, but of the two major categories of FETs, enhancement mode devices ...

Sometimes a circuit requires a data link over an existing cable that doesn’t have any free conductors for a dedicated comm link. A common solution is to superimpose a high-frequency carrier modulated ...

Courtesy of www.MikeHolt.com. Based on the 2020 NEC. Article 725 of the National Electrical Code (NEC) covers remote-control, signaling, and power-limited circuits that are not integral to a device or ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...
