Question: How do you measure inductor current? Answer: Switched-mode power supplies commonly use inductors to temporarily store energy. In the evaluation of these power supplies, it’s often useful to ...

The monitoring of current and power is more important than ever. Industrial automation, instrumentation, solar power conversion, battery monitoring, and medical measurement systems measure and log ...

A new range of automotive-qualified current sensors is addressing the growing need for accurate, isolated current measurement ...

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

A decent current measurement sensor ought to be an essential part of every hacker’s workbench. One that is capable of measuring DC, as well as low and high frequencies with reasonable accuracy. And ...

Today's SoCs (system on chip) have many modes of operation. Subsystems are shut down when not in use. When the entire SoC is in a “sleep” mode, many subsystems may be shut down or run on minimal power ...

Key considerations for using a low current source include the maxi­mum current, minimum current, and step resolution; the output settling time required; and the level of voltage compliance needed. It ...

Fluxgate current sensors have emerged as a robust technology for the measurement of both alternating and direct currents, harnessing the non-linear magnetic characteristics of ferromagnetic materials.

Current. Too little of it, and you can’t get where you’re going, too much and your hardware’s on fire. In many projects, it’s desirable to know just how much current is being drawn, and even more ...
