Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

If we dc pulse a transformer primary the output no longer depends on ampere turns ratio's. 
The turns-ratio stops applying when the current in the secondary does not flow at the same time as the current in the primary (no simultaneity = no Lenz law).  This is usually accomplished by a diode in series with the secondary.

Doesn't Faraday tell us that the output of a transformer depends on the rate at which the magnetic field changes about a conductor?
He does say that about the induced secondary voltage, but not current.

SCR's can be used too, but they have a higher voltage drop between the anode and cathode and suffer from high conduction losses (waste of energy).
Waste of energy does not matter if we have energy in abundance (due to the preceding circuit stage).

Also, SCRs cannot be turned-off when current flows through them, which leads to switching errors (especially when a non-resistive load feeds the electric current back into the power supply). 
On the other hand this could be an advantage in terms of circuit simplicity.

What if the primary and the secondary coil is one and the same? When the primary and the secondary coils are not needed at the same time then one coil only could be sufficient.

(no simultaneity = no Lenz law).
So this means Lenz law does not apply to the Back-EMF created by a coil. What if we replace the odd battery symbol in the above screenshot with a (DC-pulsed) coil? I call the battery symbol odd because maybe this battery symbol symbolizes just additional energy (from Earth), not a real battery.

And I'm still looking for a FE schematic which neither wastes my equipment nor my time, means one that works at the first go. Ideas? ::)

Yes.

Sometimes yes, sometimes no.

Then you don't have a transformer anymore, but an inductor.
An inductor can still store electric energy and release it at higher voltage, but not at higher current. See here.

No, I meant this only about a transformer.

Zeitmaschine: I've had nothing but hell trying to tame thyristors using a raspberry pie. The problem is always a ground loop in the circuits protecting the pie. So I use npn and pnp transistors, but once you speed the pulse rate up, switching errors kick in.
So if anyone has a good circuit for driving thyristors, I'm all ears and eyes.
After all - thyristors can switch killowatts very easily and they are relatively cheap.
In fact thinking about it, has anyone got a good pic or stamp circuit that switches in the mhz range?
