I want to solve the ripple problem.
going to remove all except L1

It also shows the ripples, so I can then measure everything until I find the source of the ripples, and maybe solve it

removed everything, except the C4 and L1, and the V+ diode.
It shows the negative impulse at the source, without the ripple. So the mosfet seems not to be the problem.

With my "Capacitor Discharge Resistor" video, I remembered having the same ripple, this circuit had an extra cap parallel to L1, with a diode, so the problem might be there

added a parallel cap C5 to L1, with a diode C2 to ground, so its charging positive voltage.
Tested again, and no ripple. between 30 and 50 kc/s
so C5 isn't the problem

this brings L2 into the picture.

I removed the C5 and D2 again, and connected C2 and L2.
Et voila! There are the ripples.
So the DC offset isn't causing it. it is something that L2/C2 does.
I had 81nF in the first measurements
then made it smaller to 31nF (raising the frequency)

Tuning above the resonant frequency enough will make the ripples go away, except one, but that one is normal.

So... now I will have to measure C4 and see what is happing there.

I will need to add current into the mix, as L1 and L2 are in series, and when L2 is powered, the current also flows into L1.
it seems the ripples start flowing, when the current of L2 is changing polarity, which makes sense, as this would give L1 the current path to discharge again. still this is a bit silly, but I'll see soon enough

I measured L2 voltage (yellow)
and L1 current to ground (green) pointing away from ground
This makes sense, but also is a bit weird.

L2 is series resonant so it has a current sine also, let me get my other current probe, and probe both L1 and L2.

ok, I increased the capacity of C2 to get a proper reading, tuned down to 62 kc/s
yellow L2 voltage
green L1 current
orange L2 current

current probes both pointing to ground

The current rush of L1 can be seen in green, this is from the impulse. If I measured L1 on the source side, it would be a lot clearer, as a single impulse spike.

both currents of L1 and L2 are in phase, although the series resonant current of L2 is much larger (as expected).

I still can't explain the spikes. So lets take a look at C4

orange is measured at the drain of the mosfet. I gave an input of 8V into the system (minus diode drop).

as you can see, right before the ripples start there is a "glitch"
Is this the trigger for the event?

the probe was AC coupled, so I measured again with DC probe, this is SCR15,
again that glitch. It appears to be at the max negative current point of L2, where the voltage is zero

Hi Evo Do you think you can achieve this?

so now I know there is a "glitch" at the max current zero volts of L2, but still I can't see the reason for the ripples.

I wonder if it is a reaction from the Aether, on the impulsed L2 series resonant primary coil.

And I wonder if the same happens with a positive impulse, where by the L1 coil is connected between drain and V+ supply

and C2 on the drain side of L2.

Hi Evo Do you think you can achieve this?

No I don't think so. It might be an analog oscilloscope anomaly

I mirrored the previous circuit, so now L1 is on drain, c2 is on drain, and V- supply has diode.
And again, the ripples appear.

Next question that rises, is this also happening with solenoid coils, or is it only with bifilar?

I am more and more thinking I need to use this anomaly. to get it on the V max + on LMD resonance, and see If I can get the current amplification of L3

Maybe this anomaly is really the key to making this work

and the ripples are not restricted to the zero volt crossover of l2.

Since I still can't explain the ripple anomaly,
I will use it by tuning to LMD resonance, and having only one ripple on V+max (while the impulse on V-max is not visible, fully absorbed into the C2 cap)

Since this also involves L3, C3 will also need ti be tuned for max amplification during the simgle ripple.

This is tricky but I know it can be done

I used the 135nF as C2 for L2, and 11nF for L3 which is still flipped, and should be flipped back.
This made it LMD resonant at 139.6kc/s and this gave almost the single ripple at V+max L2 (yellow)

To get the frequency lower, I will need a much larger C2, probably double, so I will order new caps.

edit:  After ordering the caps to make C2 even bigger, to tune everything down, I realized that it probably will need to be higher in frequency to work...

looks like a step charge imagine if you had the secondary in the spiral wired right

you have a ac signal imagine if you put the diodes in

2 opposing signals  dc

2 opposing signals  dc

I guess its like a bifilar coil, but switched in the middle where the 2 windings are series connected. Then you get a positive and a negative impulse simultaneously at turn off of the switch

with C3 (L3) being only 11nF the voltage was very high already,
and this was with L3 flipped, so it was damped instead of amplified.

This calls for high voltage tuning capacitors, or even better, a load on L4 to keep the voltage down.

with L3 flipped back to "normal" the impulse happens at L3 V negative max, adding up to the negative dc offset.
So this gives an significant extra charge to the L2 L3 coil capacitor.

did you see spiral wind diagram? trifilar?

Hi Master Ivo,

I just wanted to say thank you to you. Dank je wel.
Thanks for your absolutely great dedication and great videos about this topic.
I learned a lot and i hope to see more from you!
Keep it coming :)

Thanks
Dank je wel
Steve

no.

I flipped L3 over again, which makes all 4 coils none reversed.

When I had no load on L4 (open ended no ground) I could again tune into LMD resonance at a high frequency around 153 kc/s as before.

again the voltages of L3 were quickly high, so instead of blowing up the tuning capacitor board of L3, by dialing in more input power,
I decided to put a 8.2 ohm 25W power resistor on L4.

The power of the supply went way down, and the L3 resonant frequency went way up.
So, now I need more capacity on L3 again, I checked if I could tune to TEM again, but L3 could not, it stayed at a higher octave.
So my guess is I need more capacity on L3 again.

test was done with DC offset activated.

i find is strange that you not see i posted to you and thread hmm

some times we can see it some times we can not when it is so close.

i notice you have we need to focus we can simplify
you are doing this with switch over lay pancake  stan and electro did with alternator 

you have  3 coil

ivo van you show the pc of coil for this signal and layout of actual wiring of pancake i see the schematic diagram already
