What is the science behind DC DC plasma transformers?

[Salvador]

Good day , while reading about DC DC converters I stumbled upon some papers discussing a DC DC plasma transformer , the science behind it being similar to tokamak current drive or so they say , I tried to search various links for some information to get a clue about how it works but I couldn't find any info that I could understand , could some of you folks help me out with some explanations ?

A scientist named Rick Nebels is working on it as much as I can tell.
I would love to know the how it works , like do they apply a steady magnetic field from a DC winding to the plasma and the plasma somehow self oscillates to create a waveform in the secondary or what ?

Hmm, yeah, all a Google search comes up with is traditional transformers to make high voltages for creating plasmas...

Do you have a pointer to the Tokamak B-field drive that you mention? I wasn't aware that there was a net current flow around a Tokamak in the plasma. Is there one?

In a tokamak, the toroidal field is produced by electromagnets that surround the torus, and the poloidal field is the result of a toroidal electric current that flows inside the plasma. This current is induced inside the plasma with a second set of electromagnets.

This is from wikipedia http://en.wikipedia.org/wiki/Tokamak

As much as I understand I would say yes , firstly there are plasma confining electromagnets but there is also a current induced into the plasma so in the end the plasma creates its own EM field which pushes against the em field of the outer physical windings, this is how much I understand.
Looks like somehow the people working on the polywell have thought out how to use this plasma current carrying property to use the plasma as a sort of "flowing" iron core like in a typical transformer , the difference that in a typical transformer applying a steady DC would not result in a induced current but applying the same to a plasma induces somekind of flow which further can induce secondary currents ,

although as I said this is just a skecth and I kow nothing more I would really enjoy if someone could shed some light here.

berkeman , anyone?

To induce a current magnetically, the magnetic field needs to vary (increase) in time. Otherwise, one has a static field, which would be useful for confinement, but not for forcing a current in the plasma.

In a tokamak that uses resistive heating in the plasma, the gas/plasma behaves as a single winding, much like the winding in a normal transformer. One can pulse the current which causes a toroidal field, which acts on the charges to compress the plasma (j x B).

Nassim Haramein is using plasma in his patent. this information may be helpful.

I looked up Nassim and even though this thread is old I just want to point out he is one of those crazy folks who mixes science with various kinds of new age dogma about people all being one consciousness and being god like BS.
He literally makes science a religion.I suggest JeffVan you don't take him seriously.
