The lowest-cost way to achieve this goal is to use a 1-quadrant unipolar dc supply (Fig. 1a) outfitted with a polarity reversal relay. However, using a polarity reversal relay brings with it three ...

In a previous article, I wrote about generating negative voltages via a standard unipolar dc power supply outfitted with polarity-reversal relays (see “Turn Positive Voltages Negative With Relays”).

AC/DC power supply manufacturers have focused their latest designs on meeting the increased demand for higher efficiency and miniaturization in industrial and medical systems. A few of them are also ...

Most medium to high power AC-DC power supplies and some DC-DC converters include “Remote Sense” connection points (+ and – Sense) that are used to tightly regulate the supply’s output voltage at the ...

HVAC systems are essential to maintaining temperature, air quality, and comfort in both industrial and commercial ...
