Agentgates´s TPU setup with strange wavehill hump

[agentgates]

Thanks for responding. In connecting two of the primaries I was thinking of increasing output. Anyway have you tried the primary wrapped over the secondary?

Yes, I've got a coil like that somewhere. It shouldn't make difference in the operation. I just put the secondary around the primary as the latter is fixed for now. I ocassionally removed the secondary or put more and different wires on it to find any difference. So IMHO it doesn't matter which one is above until the primary wires inside are far from the secondary.

as to the right handed coil versus left handed, I am speaking to the direction in which you wind the coil, for instance look at your right hand palm facing down fingers away and relaxed, the thumb indicates the direction you wind in and the fingers indicate the wire direction when looping over the form. So in a right handed coil the wire startsby going over the top and to the left.

Thanks for the explanation. Yes the primary is left handed.

I also noticed that the secondary is wound in a right handed manner (this is what the picture shows for the one you made for Stephen I think

Yes, this is what I made for Stefan but this is bad. The plastic is to thich so the primary and secondary wires are too far, also they ar not hovering inside due to the ~80 degrees angle between them. If you decrease the angle they will hover inside like a cobweb in the corner.

@gotoluc, minde4000

Thanks to both of you. I'll be on it in the next couple of days to remove the heavy and expensive switching devices and replace them to cheaper ordinary ones those more people will be able to replicate it.

@zerotensor

None of them are my own devices. They are independent replicas. I just uploaded them onto my channel. Possibly some of them don't even work.

I will upload my own videos and will post the links here and change the description on those videos are not mine.

Hmm,
I will ask him by email,
if it is really his channel.
Maybe he just "collected" these 2 videos there ?

Yes that is correct. I have downloaded those from a Russian website and just wanted to preserve them in case if they are real as I didn't see them on international websites. I didn't look into that whether they are real.

This was a fake by user EMdevices....
and this
was a fake by user Marco.

Thank you Stefan. I have already removed that and modified the description on the other one.

@Tony,

Thanks for the reply. A few additional questions to clarify your design;

   1. from your previous posts the 45 degree angle seems to imporve the operation correct?
   2. The secondary should be close to the primary windings?
   3. The secondary should be wound with spacing between turns to reduce interaction/capacitance between the wire?

   4. Have you used a sweep generator or dip meter to determine the resonance of the primary yet? I ask since knowing the coils resonance may help match the drive frequency and using some capacitance with the primary may help reduce the driving current and possible heating.

Another idea that comes to mind is to use a 1:1 transformer to isolate the driver FET's or transistors from the primary this might help in resolving the driver heating.

Again some ideas you might want to add to the growing list you have.

I will soon contribute more than just words or ideas.
