user TURBO?s replication of Steven Mark?s TPU ?

Stephan,

If possible adjust the duty cycle down to say 5% or so

No unfortunately not with these function generators.

This is why I have to get a 3 square wave driver circuit,
which can do this all .

For real good documentation
with thses TPU units, one also needs the right driver
circuits which work flawlessly and where the
wanted parameters can be easily adjusted...

So with my fast built setup it does not make sense
to try to rebuild the TPU.
I first have to get a real good driver setup
and then I can wind some new better TPU coils.


P.S: I also tried a few various other setups
during the last 2 days also with bifilar coils.

In the Hz and 10 Hz range, you don?t see any effects
with bifilar coils.
If you wind a bifilar output coil around
a primary coil and pulse the primary normal coil with square
waves, there is just no induction inside the bifilar output coil.

But if you go to the 50 to 200 Khz range, there is indeed
some capacitive coupling and the stray capacitance
of the bifilar coil is charged and discharged during
the switching.

So in this frequency range you have some damped
oscillations at the output of the bifilar coil,
when the primary coil is switching, just after the switching
spike.

If you do this fast enough you then can have output from
the bifilar coil.
But I don?t know yet , if the capacitive coupling will
drag back onto the input, or if the output current will
be independent from the input current into the primary
coil.
But these output pulses are pretty small and
you need a lot of wire with lots of capacity to get a higher
output voltage..
Also interweaved primary and secondary coils could help this
way to make the capacitive coupling stronger.

Regards, Stefan.

well well, if it isn't sherlock holmes.... 

how is the investigation going?
nice going on the details.
so, i didn't read my bulb was fake yet in this thread......
indeed it was a real bulb and it was not powerd by the 9 volt battery.

can you calculate how long a 240 volt 75 watt bulb will burn on a 3 volt cr2032 lithium cell....on one wire?

i got a new video with a clear bulb and without the 9 volt.
there are quite a lot of rf burn holes in my fingers from sparks flying out.

i tried to measure but the equipment fails.

it has all been written about if you want to build it, please visit the books, this is the only way, they don't fall out of the sky.

Have fun
