Spare a moment’s pity for the process engineer, whose job it is to keep industrial automation running no matter what. These poor souls seem to be forever on call, fielding panicked requests to come to ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

Open-collector outputs are useful for transmitting buffered digital/pulse signals to the external world when high drive is needed. In harsh operating environments like automotive systems, however, ...

Network analysis is a powerful and well-established method of characterizing and optimizing a control system. [1] Unfortunately, making a successful measurement can be difficult and frustrating ...

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 ...
