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

On the thin red wire.
I wonder if the voltage across the blue cap is a completely smoothed dc or it has any kind of ripple at 120Hz when the device is working. If the latter is true then it can be used for sync. Perhaps the unknown 37pin of Pierre opens and closes according the peaks of this signal. A switched ground point perhaps? Or a sync method for bringing the output peaks in time accordance with the input wave? Only Pierre knows.

Interesting: it could explain why he needs this 4 ohms resistor:
To power the coils/switches with some ripple (variable current) and recover from the diodes on the other side.

cheors  I think you are close!  If true, goes to relays 71, 72    (first anyhow) !!    See pic

"I wonder if the voltage across the blue cap is a completely smoothed dc " Anyhow a much higher level!

The only BUT here is that the wires goes slightly backwards when they comes up behind the bottom relay assembly.

cheors On your CurrentVariation pic : I'm Not convinced that Pierres diodes goes to both plus an minus ? See an earlier post of mine. Reply #477 on: April 16, 2018, Page 32,

On a raw linear power supply, the current draw when charging super caps is very high.  I charge my 500F bank by a 30V 30A switch mode supply, which is current limited at 30A and the full 30A is drawn during charging. It would draw a lot more if there were no current  limit. The 4 ohm resistor is just a basic way to limit the current so he doesn't burn out the transformer. The FWBR is rated at 125A.

Its a very thin wire, it cannot be carrying much current.

The diodes are wired 2 in parallel which is  a strange way to get the current rating doubled however, maybe its just cheaper doing it that way. The way its drawn ,the diodes look like they are either side of the switch each one joined a potentially different current flow.  Anyway they just are not connected that way.
