Does "biasing" mean to "prevent saturation/overload" i.e. to "maintain balance under load"?

... got more than +280VDC that I routed to only one side of a spare coil parallel winded on one of my 2 CCs.
....Similar results was obtained just hooking up the P.S output +12V to the same coil...

Hi Roberto,
I think what you describe, is what they call "provide a bias" to the setup.
If this is the right understanding, then I think the the "biasing signal" has to be applied in opposition to the "normal signal".

Biasing the CCs
Did you apply the bias to the CCs in that way (i.e. in opposition?)? If not, maybe you can try to connect the bias signal to the other end of your spare CC windings.

Biasing the collector
If a small toroid is placed in the center of the "basic TPU" I think it should be wired up so, that the toroidal fields (vortexes) of the small toroid and the "basic TPU" are in opposition.
In this way these fields would serve as dynamic bias of each other.

I think Otto has achieved this effect through the horizontal displacement of his big and small ring. But if you don't get this horizontal distance just right .... well.. you missed it.

BTW: Why don't the two rings of the ECD bias each other properly when they are on the same level (i.e. no vertical displacement)?
Because they don't have equal length, I suppose.

Did you adjust the vertical displacement in your setup so that you see the "additional power through displacement" as Otto saw when he lifted one ring to the exact height?
It must be possible for you to verify this, as you should clearly be able to see additional output at the correct hight/displacement.

I think there will be no OU in the ECD if said displacement of the two rings is not correct.
Because only with the right displacement the fields of the two rings provide the right dynamically self-adjusting bias for each other.

@Gustav22,

I'm really glad you are asking about this theme as I think is really important.

Biasing the CC
Of course I tried to bias it  connecting either the hot side or the cold CC side (I'm speaking about the additional secondary on CC which is at the moment not used...but may be used to deliver power in a way isolated from the ECD itself). Well if I connect to the hot side I have an increase of lamp light ...the contrary the other way around. Remember that my CC is winded in CW way and the winding startpoint is near the Zero point  (...so the Primary coil is connected to +12V from the side distant from the Zero point).

Biasing the Collector
- In this case the small ring is almost in the same plane of the big one (just some 10 mm upper...for mechanical reasons...).

- With this setup I still have to adj the vertical displacement and see if there's the increase reported by Otto (at 44mm displacement).
I don't understand the reason for the small toroid on the center that you mentioned. May you be clearer?

You as well are missing one important aspect: while the Bias is correctly applyied the ECD tunig appear to be much sharper and output power increased! Do you have an explanation?

Biasing, of any form, on a resonant (magnetic or otherwise) circuit can be used to increase the Q of that circuit. It can also be used to decrease that factor.
It might be possible that 'bias', in this case, may also be used to contain or enclose or direct.

I don't believe magnetic amplification is being used here. But I do believe a portion of that theory, magnetic switching, may be involved. The magnetic bias looks to be the amplitude modulation part of the system - the  - holding the hose while walking causing more flow control - part.

I don't see where electronic bias would be an improvement over magnetic bias.

Biasing, + or - or both, can be used to place operation at a needed part of the operational curve. Even a short piece of wire has an operational curve that can be plotted. This is the way the 'tickler' coil works on a regenerative receiver.
