Attached scope shots showing stepped waveform (blue) synchronized to line sine (yellow).
Zero cross circuit was modified to add a schmitt trigger prior to output, to remove jitter.
Falling edge interrupt was used and code adjusted to ensure correct step start point.
I should mention that the line supply has slightly flat top sine, which is due to supply harmonics from
large numbers of switched mode power supplies that are in use today.

I have been experimenting with different overlapping composite waveforms with little output power. As side note, I found during this exercise, I had my coil 10 and 9 reversed, so I corrected this.

I subsequently went back to my linked coil arrangement that uses 30 coils, 15 in reverse parallel with their 180 degree counterparts.This configuration produces an output about 35% of input (this equates to about 135W limited by my voltage input ratings) and I have been puzzled as to why this waveform was different.

Firstly I found that maximum output was NOT where I had the main group of of contiguous overlapping coils, but instead it was when the rotor was over the coil 30-1 & 15-16 junction. This I call the transition region. Note: there is no series link between coil  15 & coil 1 in this configuration.

The first attached scope shot shows the unloaded output voltage. The dip in the waveform over the positive peak is the transition region from coil 30 to coil 1.
The coil switch pattern follows...
Coils 8 -15 are on and their 180 degree reversed counter part, coils 23 - 30. The coils decrement every step so 8 & 3 are turned off then 9 & 24 and so on down to coils 15 & 30. As each of these coil pairs are turned off, coils 1 to 8 and 16 to 23 are progressively turned on (initially inverted by the H bridges to maintain same polarity), so there are always 8 coils on per pole.
As the sequence progresses, the poles move away from the  transition region into the middle region of the series linked coil group. If the rotor is aligned in this area, there is only a very small output, although of the face of it, the stepped waveform is identical.

So ... what is the difference?
The middle region coils always have one coil turning on and one coil turning off in the pole group. So essentially the current through the pole group is not changing.
The pole group over the transition region comprises of two sets of coils that add up to 8 coils, these also have one coil turning on and one coil turning off however, they are not  series linked so the the number of coils in series is changing i.e 8 to 0 and 0 to 8.

In the decrementing coil group, inductance is reducing and current is increasing.
Note: The recovery current is progressively greater as the number of coils reduce.
In the incrementing coil group, inductance is increasing and current is reducing.

The overall current for the complete 8 coil pole remains constant, just as a contiguous coil pole however, as the pole is divided into two sections, each section experiences large changes in current

Note: No recovery current until 9 coils are in series i.e. No 1 coil switches off.                                                                                                                                                                                                                                                                                                                                                                   This change in current applied to the stepped waveform is key to improved induction.
                                                     
The second scope shot shows the input current from the (DC supply in purple).

Now, I have confirmed this by accident rather than design, as it was the use of only 15 H bridges that created this break in the series coil continuity.

The last scope shot shows the output power, which is only limited by input ratings.

So how to improve this? 
1. I have tested more than 8+8 coils but this is counter productive.
2. A 36 slot stator with 6 slot coil pitch would allow another coil overlap.
3. Reducing coil current in the middle region to stop wasting power as heat.

Just a small update.
Attached shows the same input current as before but input is now half sine.
As you can see, the middle region where muitiple coils are in series, is now boosted to the same level as the single coils period, which are now reduced due to the switch period being close to zero crossing.

Looks like Pierre re-surfaced...


He has uploaded two of his old videos to his channel today:

It is unfinished project and still not clear method of obtaining magnetic flux change with fraction of the power in a "slow motion" way..  For background information - the "normal" change of magnetic flux is happening too fast for proper induction in other experiments with reactive power driving a change.
Hopefully Pierre could elaborate on that?

Cheers!

A couple of scope shots from new 30HS Switch + 30LS Switch + 30 Intercoil switch rig, running a continuously  changing coil current pattern also in rotation.

Very clean sine output with minimal filtering.

Very robust boost recovery on all pulses.


Recovery does reduce input current draw.


Still grossly inefficient.

No load output.

No load output.
The input power need to be replaced with reactive power on resonant LC tank where coil is inductor for magnetic field induction there. Then you may see something out of ordinary happening when compare input vs output.


Cheers!

Basically the device is a rotary transformer but not an efficient one in my current configuration.


If you take the same coils, in this case 11 connected in series, with the inverse parallel windings (a further 11 coils 180 degrees apart) in place and apply say 30V 50 or 60Hz AC, you get over 85% of input coupled to the rotor coil. This demonstrates that the magnetic circuit is capable of achieving normal transformer efficiencies.


This indicates that I am still way off base in a stepped synthesis of a sine.


This is as much about coupling energy, as it is about not wasting energy. There is way too much power being dissipated as heat in the coils.

The waveform is intended to synthesise a 50 or 60Hz sine in a manner that allows energy recovery.

In DZ2 No magnetic field really moves.
It acts like in a movie. Deceives the eye and the brain.
If you examine the movie frames, they are actually many still images.
The same with the different sections of magnetic fields.
SEE his illustration with the jumping LEDs. They jump and increase and decrease in light intensity. Nothing MOVES!
Imposing building. A lot of things. A lot of money spent.

Yes , Hello somebody will be kind to show the downloads videos from Pierre? or a site where we can see It?, maybe some messages from pierre direct to the group. Thanks a lot for help .

He was harassed until he left the feed. Just as they do to all who say this is OU.  They come out of the walls immediately and keep it up until they leave.


I personally think he would have had more luck by charge pumping caps and then dumping them into the coils with a fast diode and cap set to capture the power used to hit the coils. Then at intervals use a make before break to keep a charge set on the output and link the transfer cap back to the input via a isolated dc-dc.
