I watched several videos about Miller capacitance, but I've enjoyed this one the most

A good explanation. Something for me to consider (better) than I have in the past. Thanks.

A unique video that experimentally explains what you only see in diagrams. Thank you for this excellent channel.

I'm using MOSFETs in a new design for the first time ever, so this was useful! Gonna be measuring some switching voltages tomorrow 🥰

Very nicely explained!! Really understood the Miller plateau well!! Thanks a lot!

This is a good course. Thanks!

Is there a follow to this? As a brief demo of the Miller plateau, it's okay, but what most folks really want to see are some concrete examples. It's reasonable to skip the "bunch of maths", but then why not simply connect a multi-turn pot of about 250Ω as a gate resistor and show how you would optimise the switching for a given mosfet and load? You could easily use the Arduino to switch the mosfet faster and faster in order to see how it heats up and demonstrate the upper limit of the gate drive resistor.

Good video for basic understanding of MOSFETs.. good video.

Thanks! 👍

Great video

Thank you very much sir, it couldn't be clearer.

Interesting to see slowly turning it on versus slamming it on, both with probing the curcuit and radiated energy. Would have really liked to see the results with different resistor values. That active probe most certainly would give infinitely more accurate results compared to everyday 1/10x probes, which would be even more beneficial to see. Does rise and fall times listed in the datasheet coorelate completely with the input and output capacitance? What other things would you consider for rise and fall times to optimize switching speed? Look forward to a follow up video on this subject

Thank you for the comments. I provided a response here: www.element14.com/community/docs/DOC-95249/l/workbench-wednesday-25-measuring-a-mosfet-s-miller-plateau#comment-268120

It kind of failed to actually explain what happens but hey, so long as the giant power pro box is in shot that's that matters to the producers.

Yeah, he barely mentions "miller capacitor" and that's it.

What's the make/model of the hall effect current probe? Thanks.

R&S RT-ZC15B. It is a re-badged Hioki with custom interface for R&S scopes. It is the same probe that all teir 1 scope manufacturers use/sell.

Hi, I need help, this is a digital temperature sensor on the pellet burner electronics. Everything works well but I need a little diversion on electronics. The thing is that at some point I need to tell the electronics that some temperature has been reached and if creativity has not been reached. How to influence that temperature via a sensor. There are three wires on the sensor: green, brown and white. Green is electronically connected under one connector and brown and white are connected together under the other connector. So, three wires, two connectors. Thanks.

and how does that remotely relate to the topic? go find a forum.

Hello brother Ilike your video thank you very much

Noice

no first ?, ok I'll "transmit" it

Is there no better way to explain how mosfet works ? this is fast and complicated.

maybe this is not a explanation of how mosfets works...
