Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

Hi All,
I have been watching this with great interest but a few basic things don't make sense to me, there is probably a simple answer but I need to ask the questions.
1. If there is a 4 ohm resistor in series with the transformer which then charges the supercapacitors assuming 24V DC after the rectifier should give 6A on the DC, which would be approx 1.5A on the 100V line.
If there is 2.5A in the primary then I would assume that there is 10A in the secondary of the transformer and this then does not make sense with a 4 ohm resistor.
I am sure there is a reason for this, but it is bugging me.

I am working on assembling the parts and have come to the conclusion that if each coil is driven by an H Bridge then it is possible to cover all options of coil connections using the H Bridges, if the coils are connected in series then you would get different currents in them depending on how they are switched as you would end up with coils in series which would effectively alter the resistance and therefor the current.
Connecting H Bridges in place of the relays will cause issues due to the freewheel diodes.

Would the recovery system work much better if high frequencies were used.

Welcome dhodge,
I just approved your first post. However, this topic is more for the builders. Probably what you're asking about has been covered in the first topic which is still viewable to the public. Please search there for possible answers to your questions: http://overunity.com/17609/170-watts-in-1600-watts-out-looped-very-impressive-build-and-video/#.Wtj8ftYpDM0
Once you're convinced and you decide you want to build a test device then please post a video of your progress and feel free to participate here.
I'm sure you understand we cannot stop our research every time someone asks questions that have probably been covered.
Kind regards
Luc

Fr.  Bienvenue dhodge,
Je viens d'approuver votre premier post. Cependant, ce sujet est plus pour les constructeurs. Probablement ce que vous demandez a été couvert dans le premier sujet qui est encore visible au public. S'il vous plaît chercher là pour des réponses à vos questions: http://overunity.com/17609/170-watts-in-1600-watts-out-looped-very-impressive-build-and-video/#.Wtj8ftYpDM0
Une fois que vous êtes convaincu et que vous décidez que vous voulez construire un appareil de test alors s'il vous plaît poster une vidéo de vos progrès et n'hésitez pas à participer ici.
Je suis sûr que vous comprenez que nous ne pouvons pas arrêter notre recherche chaque fois que quelqu'un pose des questions qui ont probablement été couvertes.
Sincères amitiés
Luc

So that would mean north south sine like wave in the rotor followed every 180 degrees by a square wave when you flip the poles then followed by a sine wave?

L192

Nope, Each half the code is changing polarity in succession. 5 poles = 60 degrees or one half the code cycle, while Pierre's is 6 poles.
E.g.
HBridge 1-5 is North, next
HBridge 6-10 become South, then FULL off position to collect, this is the double off position, and is seen on Pierre's scope shot.  This is the inductive kickback from the coils and load.
The other two 120 degrees are doing this at the same time.
You always maintain an opposite field at 180 degrees.  You have to have this for an AC output!


The code is running in a repeat loop at 120 degrees with a small rest period before repeating back to the start.
Every 60 degrees the polarity is switching, again this is each half of the code. 
The code is working only at 120 degrees repeating back to 0 degrees.


GotoLuc, is only doing one half of the correct switching, He is not getting a strong polarity of NS across the load!  Swing the last half of the code...and I believe we have something special.  A much stronger potential across the load.


What does a magnet do to the current flow when it shifts from N to S?  Without current flow moving back and forth, you have a very weak AC generator output, right?  Easy questions, just proving a point.

Hi Ole,

your animation doesn't run. You may have to zip it and post it.

Hi L192,

I attach it again. But this time it is a video file (.mp4). I hope this will work as it looks like only the first frame of the animated gif went through. The .mp4 file size is only a fraction of the animated gif file size. Put on repeat mode in the video viewer to see it loop like the original gif-file.

Regards
Ole

Doesn't that make a discontinuity in the waveform?
