Selfrunning cold electricity circuit from Dr.Stiffler

@DrStiffler

From my observation the DC current flows only in one direction from the Positive node to the negative node. There is no bidirectional DC current flow, neither could there be since that is the nature of DC. The AC voltage component simply sites on top of the DC voltage. Yes you can vector sum the amplitudes of the DC and AC voltages.

@PCB
Well thanks for the lectronics course.

So guess you are ready to tell us all how it works, great guy.

@DrStiffler,

(Hi BTW)

As far as I can remember there was already some consense
that the 2 slow diodes of the AV plug operate as a pseudo
random modulated charge pump.
A higher voltage on the charge pump can transfer more charge
at the same capacity. (which is a highly nonlinear capacity in this case).
During the charge transfer, the impedance of the AV plug is highZ (with high
voltage).
By connecting a resistor to the output of the AV plug - you damp the voltage
during the charge transfer by a high degree -> no output.(low charge transfer)
->The output resistance of the AV plug is only low in some part of the cycle.
By using a SIDAC, NEON or a synchronous rectifier - you can extract(harvest)
the transfered charge in the moment where the output resistance of the
AV plug is low without dampening the charge transfer.

what do you think  ?

@fritz
I would say (cautiously) that is pretty close to reality.

just to round it up -
During the phase where you can extract energy -
the output is kind of current source - which means that
the output resistance is still high - but load at this point
in time doesn?t effect the charge transfer.

Or a complementary approach - even if its possible to
load the charge pump with resistive load attached - the pump has
to be discharged for the next cycle because of limited capacity.
At high voltage the discharge rate is faster.
This would be the matching condition vor the inductive part
of the story.

Is the input impedance of an AV plug capacitive - and the output
resistance inductive !??? a switch-mode gyrator ?

crazy plug.
