Looped is only after inserting the rotor. We do not know this, however, 100%
In my opinion, diodes do not pay so much energy to make it possible.
Maybe I'm wrong but after a few tests it looks like that. Perhaps this secret Pierre increases it.
Pierre separates the rotor from the stator with paper. There is no free passage. There is a "jump".


Jerdee: you've come up with this FET well. Pierre said he uses only 1/2 of 48V -> 24V maybe for that.

Strength of the fields is only one of the keys. However, just a strong rotational field is NOT going to give you OU. We have to study A/C generator basics.  The rotational field is only one part of the equation.


Pierre vids only show relays not using double throw. Look closely, ground is skipping on the even relays, while positive skips on the odds.  So he is only using one direction.  If Pierre is looking for more room for improvment in rotating the field, he needs to use H-bridges.  By allowing the positive/negative rail to flip, you can double the amount of current field strength.  Look at sche again, and compare to Pierre's.  Pierre is only doing ONE DIRECTION of CURRENT in his relays.  So, using both sides of an H-bridge is an improvement for sure, but is it diverging to far from Pierre's original design?  I  don't think so, you still can use a boost converter design with diodes to recover with polarity flipping on your H-bridges. A boost coverter does not care about your H-bridge's direction. You can recover in either direction.  So you improve the field strength, you get more current into the fields, you still maintain rotation of the fields and you can recover the inductive charge in both directions.  So why wouldn't this improvement NOT be a benefit for Pierre?


I just keep racking my brain on how he is feeding DC into his cap bank and recovery from the coils to the same cap bank.  Anyone that knows how to deal with coil recovery, knows this can't be done, UNLESS you have an additional switch.  Could this be why he left pin37 in his code (has no LED blinking) with an additional transistor?  It's very possible.  Please keep in mind that his original code had a full off position at the end of the loop.  I've already proven this with audio examples as well.  Go back to my posts.  BTW, you have to nudge the audio earlier to line up with the lights, sound takes longer to travel than light when recorded.   So it is very possible that this off state of all of his relays are the extra step to RETURN the boost cap back to the a source cap bank.  Then the question becomes, WHERE IS HIS EXTRA RELAY?  You won't find it in his vids.  I'm left thinking that the off state at the end of his code explains his return current.  Review sche below.


One final thought, his current limiting resistor gets very hot, and mentions replacing it in his video.  If he is not using any additional switch for recovery, this explains why his current limiting resistor get very hot. Could this be our explanation we are looking for?  With no 37th switch/relay for recovery, forces him to tie source and recovery together but separated by the current limiting resistor.   Maybe the current limiting resistor plays a much bigger role than we think?  This could explain his[size=78%] source current, can't go through the current limiting resistor quick enough, and yet, his recovery has NO current limiting applied.  Seems like a very odd way to deal with recovery.  Am I wrong?  This form of diversion explains why he is generating large amounts of heat.

Hopfully this all makes sense and why we need to understand how he is returning the inductive charge back to the source caps.

On Pierres power supply, the series resistor would be required for the initial charge, as the current draw will be very high.

On my 30V 30A switch mode supply, the charging current limited at 30A and without limiting it would attempt to draw over 100A when charging the super caps.
His FWBR is rated for over 125A continuous but the transformer isn't and so he has the resistor to limit the current. The resistor dissipates power unnecessarily during running and that could be fixed with a switched mode  power supply with current limiting.

r2fpl,


Totally agree that diode recovery is not enough.  It is only one part of the equation. However in a generator you have an amplifying effect and the diodes will recover more once amplified.    Again, study AC generator basics.  You’ll see what I’m writing about.   Just like what Pierre has stated, a rotational system will not give you OU, it’s like an engine without pistons. Thanks for pointing out the 1/2 of 48V.


@L192,


Yes, I totally agree once again.   The current limiting resistor has it’s role for charging the cap bank.  I understand this already.  I’m not easily convinced it has another role either.   The switched mode power supply with current limiting would help as well.  The current limiting resistor is wasted heat!


Jerdee

Power from diodes go to directly to cap. Only power supply from transformer is connected to resistor.

Why ? all the current goes from capacitors to relays ?

ONLY TWO THIN WIRES POWER RELAYS

it would mean that the current is created on the rotor, only ?!

Pierre,

I know this secret. I will keep it for myself until others know it or tell it.
One of the films is "visible" this secret. You need to know what to look for and what is missing.
I confirmed it the way you did it and now I understand your surprise successfully!

I wonder about the time of work, and probably you too. Maybe you already know it but it's unusual.

Thank You !

r2fpl,


Your email is kind of a mystery. Did you figure out how to get your prototype to work? Can you confirm you successfully replicated Pierre's device?


Also, what do you mean by time of action?? Sorry, but your English is not very clear.

...I wonder about the time of action, and probably you too. Maybe you already know it but it's unusual.

Sorry PmgR,

This message is for Pierre. He will understand it or not.

...I wonder about the time of work..

This is my 30 slot relay build.
The diodes are paired, each is rated at 10A continuous 50A pulsed. These recover narrow spikes of charge current to the super caps at each coil turn off.

Good job ! Everything is nicely done

I used diodes: stth12r06d

WOW!... excellent job L192
Is that a 30 or a 36 slot stator?
How many segments surfaces does your rotor core cover?

Today I received the 40 Heavy Duty Dual Half Bridge
Thanks for sharing
