Wireless Power RC Car
HTML-код
- Опубликовано: 15 май 2021
- This is an upgraded version of the wireless power transmitter from my previous video being used to power a small 3.6-volt RC car. The transmitter/receiver resonate at 100 kHz, and a bridge rectifier on the RC car feeds a DC-DC buck converter that steps the voltage down to 3.6V. The car pulls around 1 amp, so the transmitter has no problem powering it as long as it's inside the loop or within about 1 ft outside the edge.
The transmitter runs at 31V and consumes 3-4 amps depending on the load.

You make fantastic videos. All information, and no waffle or bullshit. A pleasure to watch!
Cool stuff bro!
Great example of how wireless charging works
Nice Video!!
You could have tried to mount the TX coil a few feet overhead. Or even better, created a few more TX coils and mounted them overhead in "overlapping" patterns.
If it's ok with you, may I suggest that you use supercapacitors, they can hold way more charge but they take some time to fully charge, which I believe your wireless power setup can charge up rather quickly...
Yes, supercapacitors would definitely be effective for this project. However, my goal was to continuously supply power through the wireless circuit rather than charging up batteries/caps and then running off them. The purpose of my big capacitor cluster on the RC car was really just to buffer out any sudden voltage changes so that the DC-DC regulator didn't have to work as fast.
Hey thank you so much for your support. I have made it. Obviously I have modify some of the things. And I made this project for powering up a drone. And it works. Drone perfectly fly without battery.
Great transmitter power, what if transmitter coil make looks like spring shape? So rc can thrue every layers of coil ?tx for posting
Like a flat "pancake" coil? I haven't looked into it, but it seems like it would work
@@HyperspacePirate yes looks like pancake coil (series) or looks like dart board (pararel) 😀..or transmitting power by laser light dirrect to your rc ?i dont know..i just imagine😆..cheers.
Hm. Something flying that fits the ring of the power receiver? Lets see... an airplane wing generates lift so if you have something blowing out air in the center towards four wings arranged around it (or a 3D printed ring with a wing shape for when wind flows out from the center?) using a fan and perhaps an 3D printed air guide to direct air towards the wings (or ring) to generate lift? If you only want to use one fan to see if it can lift off rather than four for a controlled drone this might be a unique project. Haha!
My thinking was just a very lightweight drone with long arms that the motors mount to but also act as the supports for a lightweight aluminum receiver loop (aluminum is less conductive than copper, but the conductivity-to-weight ratio is nearly double, which is more important for a flight vehicle)
This with drones would be what imma do
Hi sir in my college we are doing a wireless power transmission project,,
Can u please give some suggestions about project,,,
How to contact u sir???
That's nikola tesla's dream...
>make wireless car
>look inside
>wires
Now do a microwave one
what is the size of the transmitter coil?
30" diameter so about 76 cm
@@HyperspacePirate can I use 100uH inductor instead of 120uH? One more thing is that " Can you make a separate video on how to make ferrite core inductor?" I'm pretty much sure that it wil help many people out there who are regularly following your videos ☺️
@@TowfiqAhmed3ELab-Bogura Yes, there's a relatively large range of inductor values you can use. In general, I try to keep them at least 10 times larger than the inductance of the load on the ZVS driver's output. Going a little less is ok, but i prefer to add more if i can.
As for the ferrite core thing, i typically just buy them or salvage them from discarded power supplies. Typically it's not worth the effort to wind them since they're pretty cheap
@@HyperspacePirate thanks for your reply
@@HyperspacePirate Bro my transmitter coil and the resonant capacitor are getting hot whenever I turn on the circuit for 1 or 2 minutes. what is the reason behind this?
Hello, any chance to cooperate?
