Hi Ron,

I ran into a rapidshare-error stating that this document is not allolocated to a Premium- or Collector's Account and can therefore downloaded only 10 times - the limit of which is reached already.

On his homepage there is a lot of blah blah and no description of the principle and of course you must by his books :

Yes, sorry about that, Mark J suggested I put it up on sendspace... which I have done
sendspace tells me it is there for a "limited time"

Took ten minutes to upload at 38 Kb/sec
so sendspace is no speed ball

  A shorted highimpedance coil current will happen at a different time than the exciting magnetic saturation change.  This phenomenon can be exploited on a solid state level also.  Input spike on input winding saturates the core while inducing a voltage in a shorted highself induction coil.  The current in this coil is delayed not  effecting the impedance of the core to the exciter signal.  Then current flows in shorted coil and is inductively coupled to the load windings.  You could use two torroidal high frequency transformers for this.  Pulse the primary on one.  Feed the high voltage secondary to the primary of the second torroid.  Feed the load from the secondary of number 2  torroid.  Make sure to use a resonant lc setup to feed the pulses into the primary or exciter torroid.   An active element like an avalanche diode in series with the exciter torroid output winding  and the output torroid primary will  help the tendency of the circuit to drift as the core magnetic parameters change.  Active tuning of the oscillator always helps but the circuit should run with gain.

THANKS SPARKS,

I AM QUITE CONFIDENT THAT IF A RESONANT PRIMARY PAIR OF COILS WERE CONSTRUCTED FOR THE BI-TOROID TRANSFORMER
IT WOULD GO OU QUITE EASILY.

Do you know what 3D software your Dutch friend Steven is using? Looks like it could be SolidWorks, or Cobalt by Ashlar, but there are a ton of 3D modeling packages out there.
