Agentgates´s TPU setup with strange wavehill hump

[Magluvin]

I have stayed out of it to give a chance for tony to finalize, but the same question comes to my mind. How can a dc line on the scope remain on the sec. if the primary is pulsed? That would assume that something is still happening in the primary or within the coil as a whole, during the off cycles. To have a solid dc line along with lil hump pulses on the sec. would suggest that the coil is acting as a capacitor of sorts. And with so few windings, I find it hard to comprehend.

Pardon my question but in photo 281 the area on the waveform under the zero line roughly equals the area above the zero line (the peak). This would imply an AC oscillation on the secondary, not DC. correct me if I'm wrong, but I have been often fooled by this.

Also photo 254 was earlier touted as being a correct response on the secondary and now is stated as incorrect.

If you believe your secondary is producing DC, you should be able to put a cap on it without any problems. Use an isolating diode if necessary, but shouldn't be required.

A diode and cap in the forward direction and diode and cap in the reverse direction on the secondary with small loads across the caps will quickly give an indication of DC balance or imbalance or whether your secondary is producing balanced AC.

Just a suggestion as determining DC from an irregular waveform can be tricky.

Thanks for all your work.......V

Ignore the negative range as the spikes will jump together when I increase the freq and voltage. The negative range is due to the very high voltage going in. (34V)

This was never stated as correct:

as that coil didn't make a full 36 turnes, only 12 or 24 with 10 degrees gaps. That is an incomplete circle and you'll need to struggle to clean it up with LC and much loss. I posted that to show it is incorrect. ou can still make OU with that but the performance will be high below the optimal.

If I did that then was not intentional (perhaps I got mixed up with the numbers) and please show me the comment thus I can correct it.

To have a solid dc line along with lil hump pulses on the sec. would suggest that the coil is acting as a capacitor of sorts.

That is the point. The secondary behaves as a cap. Take a look at the previous photos with 12V ~0.2A going in. You don't need to go above ~20V with the voltage to get spikes without negative range. That negative range is due to the extrememly high input voltage (34V).

Presently I'm winding Stephans secondary so I decided to make another vid with that.

The picture of the light bulb hooked up to the singe secondary winding, is the light bulb actually lighting or is that just the cam flash?

=============================

SM said in his videos that the Output from his TPUs was DC with AC Hash (pulses) riding on it.
