How Does Wireless Charging Work? || Crude Wireless Energy Transfer Circuit

In this video I will show you the operational behaviour of a transformer and how we can alter it in theory and praxis in order to create a crude wireless energy transfer system. Along the way I will also talk about the QI standard and some of the disadvantages of wireless charging.

How is it possible that @GreatScott, despite English being his second language, can more clearly and concisely explain electronics than any teacher I had in college?

[Nerdforge]

I always feel if I watch enough of your videos I'll become an electrical engineer! Great video as usual, keep it up man :)

[syntheticelementvids]

What I love is that he takes the time to explain it for us little people. He takes simple ideas and using simple vocabulary explains it for us regular people.

That's by far the best DIY wireless power transmission in Youtube. Explains the theory in an understandable and focused fashion, and goes through the steps towards the system tuning. Great job!

[sammymorini]

I honestly love watching your vids because of how well you write.... the lessons are a bonus :D

[BrickyVideo]

Anyone else watch these videos even though they have no clue what anything means?

[محمدالشمري-مسط]

I am an Electrical Engineer and still amazed by your videos, keep it up

[ramonimbao_]

Wow. I'm having flashbacks of lessons from my first and second year in university. You're a great teacher!

[MichelPASTOR]

Thank you ! My knowledge about transformers always lacked a bit. Probably the video I enjoyed the most from you even though they are all top notch ! Cheers.

[Bariq]

this is one of the few videos from you that I completely understood/reviewed. they drilled this concept in our heads in school.
thanks for making this video.

I didn't understand anything this guy said but his drawings and big words kept me here

Great information! I don't own a wireless charger, and I always assumed that the base contained an iron core, similar to a metal detector using ferrous metals in passing vehicles as a core for presence detection in some traffic lights. I never considered using a tuned LC circuit! That is brilliant. I always enjoy your videos, and this one was even better than usual!

Your penwork is satisfying to watch, both for the pen and your way of using it. Thanks for the explanation too.

[videomatico]

"You can always create your transmiter and receiver circuit from scratch" Looking forward for that!! Great videos!!

[cyancoyote]

Don't know what he's talking about, but his videos are great.

[NotDwight]

Oh my god that handwriting is BEAUTIFUL.

[WAQWBrentwood]

The best part of these videos is, not only are we shown how these devices work but the why! 👍👍👍

[ritvikagnihotri]

this guy is a natural.. everything with explanation

Hi GreatScott,
This video particularly I've seen 5 times as my reference to my wireless charger project. Thank you..

By the way, about the inefficiency of Qi charger you calculated in this video, please note that you put the mWh meter before the PCB transmitter which contains electronic. in my opinion, mWh meter should be placed after the pcb and before the coil. Let me know if I'm wrong.

well thank you again for this video!!!

[thescreamthescream]

the way you explain makes me love electronics :)
