Successful TPU-ECD replication !

Hi guys,

@Otto

I did the test, in my setup I used ATmega8 as generator which drives the IRF840 directly, without IRF7307 becose they need to be pulsed with negative half-wave pulse from generator, if i understand correctly the schematic diagramm from *.pdf V1.0. You see, Im not a profesional High-frequncy/radio/analog schematic guy, Im just a programer with some
electronics skills, so I think this 900V kicks is a so called backEMF. Am I right?
Indeed, in series CC conection this kick are bigger then in parallel conection. Why it so? Inductivity of the coils is bigger?
Very unusual coils, I can't wait to finish my second oscilator to apply two frequencies.
Its obviously better to make one big CC coil over all collector wire... I think...

@Otto,

I put scope probe on MOSFET drain, and scope gnd on the common gnd....
(scope: 100V/div 10us/div, oscilator 50% duty cycle)
So this small hash on the picture is a seed? Or I'm on the wrong way?

Hello all,

@sn7401

seed??? hmmm.....looks more like the beginning of something big...its good.

@Otto,

have you seen this before?
what do you think about this coils?

Hello all,

@sn7401

never seen  it but I suppose to know from where you got this drawing.

I would be a total idiot if if would say its bad.

So, as its easy to build just do it!! Build it, test it and tell us what you have.
