The importance of the input-voltage range in power-supply design. Using simulation to ensure the switching regulator is operating properly. A power supply’s source, in actual use, is never ideal. The ...

Although variable DC power supplies might appear to be relatively simple devices common to every engineer’s benchtop, they are actually sophisticated instruments. They must reliably deliver voltage ...

Every automated test system that tests electronic circuit boards, modules or equipment needs one or more DC power supplies. Specifying the right supply involves more than just finding one that can ...

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 ...

Different components affect system accuracy. Shaury Anand, of Texas Instruments, explains how to choose those most suitable for a precision DC power supply design. Test and measurement applications ...

With the increased use of battery-powered portable electronics, you might find yourself faced with testing the battery chargers that keep these products running. A battery charger is just an ...

If you work on simple digital projects, just about any bench supply will offer the voltage and current you’re looking for.

The R&S NGT3600 series delivers up to 1800 W per channel, dual-channel flexibility, ultra-low ripple, and precise ...

The harnessing of electricity has played a pivotal role in human history and has exponentially expedited our growth as a species. Since becoming a household commodity in the late 19th century, ...

We all like to keep our network gear running during a power outage — trouble is, your standard consumer-grade uninterruptible power supply (UPS) tends to be overkill for routers and such. Their outlet ...
