In the video after the break, [Xavier] goes over the theory of how it all works, but the short version is that you just need to use a Current Transformer ... charts and graphs on the go.

[Kalle] tipped us about a quick project he made over a couple of evenings: an inductor saturation current tester. All the components used for it were salvaged from a beefy telecom power supply ...

Groomed for detecting current in voltage regulator applications, the HM69S series power inductor maintains a constant DC resistance value with a shift of ±2% at room temperature and 7% over a 100 ...

This “Rarely Asked Questions” blog post presents an optimal way to measure inductor current, opening a window into whether the right inductor was selected. Answer: Switched-mode power supplies ...
