As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...

If you work on high-current dc power supplies or motor-control systems, you probably don't want to break high-current paths to insert shunts for measuring current. Although engineers have known and ...

For the PDF version of this article, click here. When designing converters, it is often desirable to measure the dc current coming into the converter. This is particularly true when batteries are ...

Monitoring the current taken by a mains-powered appliance can be a challenge, particularly if the application demands an inexpensive solution that must provide galvanic isolation for user safety.

[DainBramage] needed a DC ammeter to check how long his amateur radio station would be able to stay powered on battery backup power. The one’s he already had on hand were a Clamp Meter, which could ...
