Agentgates´s TPU setup with strange wavehill hump

[agentgates]

The coil with 6 primary. It will be 3 but I want to vary the connections to find the one that will give the best performance.

3 primary coils on.

Scope shot, one primary coil fired. This is not the best shot as there was no pull down on the fet right now so there is oscillation behind of it. The important is the rising edge.

6 coils in series as follows, equivalent to one coil of the previous designs.

Scope shot, 6 primary coil fired connected in series without load. The oscillation is disappeared.

Same with load. (240V 50W halogene bulb)

The input was 17V and some mAmps (unimportant for now).

The reason of the multiple coils to fire them each other and put those peaks onto each other. The more you shoot after each other the higher it will rise as lenz-law problem is not involved.

I'm still on the driver circuitry and diagram to comply the latter. Keep on saving the photos and descriptions guys.

Hello agentgates, Great work!

I think you got the pic for the scope shot confused...no scope shot

[hartiberlin]

Here is the scopeshot:

The question is, where the zero line is at and what kind of DC
level do we expect ?
Is the zero ground line where the left red maker is at ?
Is that the input current or input voltage ?

Here are a few pics:

@Agentgates,
what DC level do you mean ?
The spike or the levels behind the spike ?

@Agentgates,

The red line is CH1 on the screen. One unit is 50V. (See the bottom left corner)

I make another shot with peak level indication, that output looks over 50V. This device will be far better than the previous one. Thinner primary and more turnes on the secondary. One IRFP460 driving them. No significant heat.

UPDATE1

Here it is.

Lower voltage on the input side: 15V. It is unimportant as you can decrease it after you reached the necessary output. So you will give it 1V or 2V spikes when it is shooting in series and simply varying the freq and peak.

(Soon I'm bringing the vids with the driver circuitry)

UPDATE2
sorry for the bad pic number

UPDATE3
sorry again, now I really fixed the pic # after I slept a little And that is not an illusion there in the bottom right corner...
