Agentgates´s TPU setup with strange wavehill hump

[hartiberlin]

Hi agentgates,
to what DC level do you refer on your scope shots ?
I just see the backemf spike from the coil
and a bit selfoscillation of the coil, but no real DC level.

Where is your zero ground line on your scope shots and
do you have a picture or a video of your device
lighting up the 50 Watts bulb ?

Many thanks in advance.

Very nice primary coil! The tube is perfect, the wire is perhaps a bit too thick so you will need a strong switching circuit. Later I figured out we can decrease the incoming juice by increasing the number of channels. But anyway, try it out and let us know how it performs.

I made that coil in haste. By the few differences in the pics, I went with the angle you see on the primary.
But now it is 45 deg. I understand NOW that it is still being tested and the theory is not fully complete.

The theory is fully completed, the device not as I am a perfectionist but already operational and gives usable energy. We are already on the second stage and all what I am doing now just simplifying the device to help you all in duplicating it.

It just came to me as to what might be going on, a vision of sorts and came to some fair conclusions according to these principals you laid out,
1 The secondary need not be in the middle of the primary, or wrapped by the primary, but proximity is necessary.

Yes.

2 the new and hopefully final deg angle is 45, and it probably should be. we will see. It also makes for more inner and outer primary "crossings"

Yes and to make it clear again, this is vital benefit to increase the output voltage. What is wrong if you make crossing or touch on the same coils turns. So avoid PRIMARY-PRIMARY touch and SECONDARY-SECONDARY touch and increase the # of PRIMARY-SECONDARY crossing to increase the voltage output (by the secondary turns). If the current is not enough, you can use thicker for secondary.

3 Secondary should be less turns than the primary, or at least not more.

Don't count the secondary. Try it. If the current is low, use thicker wire. If the voltage is low use more turnes. But later when I am done with the 3x channels it will be even less important.

So probably the best way to go about it all for the tube style is to use pvc tube with pins on the outside and just zig zag the primary winding outside the tube. This way the primary winding "crossings" are close in proximity also to each other, thus when a secondary is wrapped to it, the inner and outer primary crossings are equally in proximity to the secondary.

Yes I have already solved this thing, read the previous posts. Presently I am cutting the vid and will post it in a few hours.

I am picking up some more wire today and will post pics later.

Thank you.

Are you saying that there are even more electrons moved besides the normal electron flow occurring right after switching off a coil?

Yes, this is all I am saying.

teslalset, the primary winding on that coil is 0.74mm and gets warm. Think of that how much energy you need there to get the solder molten inside a 500W IGBT in 3-5 sec and the zinc plating on the back side "wavy". (BTW, this thing is already getting obsolate and post the picture soon with the refined version)

I didn't photo that yet, but will do it in a few hours with vids and photos. (BTW I fried my last fet driver accidentally by closing the output on the poor wireing, so temporarily I'll have to make one from discrete devices)

I just see the backemf spike from the coil
and a bit selfoscillation of the coil, but no real DC level.

That is obsolete, please read my previous comments. The new spike is a beautiful HV high current dome in the positive range. (new winding technique with gaps on the secondary)

Where is your zero ground line on your scope shots

A tiny arrow indicates it on the left side.

and do you have a picture or a video of your device lighting up the 50 Watts bulb ?

Yes, soon I am posting them and sorry for the delay with it.

Ok, fair enough, I guess I have to believe you.
I am very curious how this replicates. I am standby to do this at a later stage, I am waiting for components to build a universal coil driver circuit first.

Thanks for having patience with the stubborn ones amongst us
