Combined inductor and current sensor 

What's funny is I suggested exactly this a few months ago to a bunch of EEs and they all shot the idea down - "it wouldn't be reliable", "if this worked someone would've done it already". Glad to see the idea wasn't as silly as I thought.

Very intersting idea👍

Great video! Thanks, Prof.!

Neat idea. EI core with air gap in the middle seems a good compromise from construction standpoint.

Thanks professor. Do you know what kind of sensor this is? Would that be better than a separate winding for current representative measurement?

Dear sir, how do I get these slides

Very nice. An accurate measure of the inductor current (minus the increased leakage). I also like the EI suggested by Pásikavec. A question, at 0.51 minutes you show an RC across the inductor and say it measures the voltage drop of the internal resistance of the inductor. The output of the switch and the cap are both very low impedances, therefore, IMHO, you are just measuring is the voltage across the cap. To confirm, I modeled this, setting the values of LR and RC to get the same waveform. I doubled the inductor resistance, doubling the voltage across it, the voltage across the C remains unchanged. I repeated this but halved the inductor, voltage across the inductor resistance doubled, the voltage across the C remains unchanged. Am I missing something?
