JNL is doing a Meyer's replication

@Alan,

Thanks a lot for the datasheet!
I did not succeed finding it.

What would you advice for the HVDIODE?
A diode from a Microwave Oven, or some 1N5408 in series?

I think a microwave oven diode works well, but I'd say, try em both

The secondary will be 550 volts, also the HV diode is necessary for the high back emf kick (But I am not sure about that, anyone?)
Also watch this, I'm sure it will help you: http://www.youtube.com/watch?v=YSmxliLwhT8

Hi Guys,

I have all the stuff to replicate this JLN's experiment (http://jnaudin.free.fr/wfc/)
the Stainless Steel tubes, the bifilar coil, the 4093.
I just lack of this BUK416-100 N-MOS Power transistor.

 

BUK 416-100 
Vds : 100 V.
Id = 150 A maxi.
Ptot : 410 W.
Rds : 0,009 ohm.
Dim : 38 x 25 x 12 mm.

59.90 Euros.....

I'm far from an electronics specialist.
I'm just wondering... According to the circuit:
Do you really need such an expensive 'beast' (150 amps max)
Is the diode part of the the transistor? If not it is not specified.

Transistors are cheap , although this1 is hight power  ... and it is very important that it will is low resistance1 (drain to source), also it may be fast recovery transistor ...and so on. This 1 got 4 connectors also it may be with 2 gates ....
I do not find smart to use so expensive transistor there is just no need for it ...

And about amperage ... U may need 410 w transistor after all coz alternator in car is generating up to 1 KW ... Any way hes using this1 as switch so i do not really know ... There may be no need for 410 W ...

@Alan, Jokker

Thanks for your "feedbacks".

Yes, 550 volts for the secondary. 220/12*30 =/= 550 Volts (without any "back emf kick").

I guess I will use:
one IRF540;
a second 4093 for the 2 square wave generators;
a 12 volts DC supply for the 4093s.

According to the circuit, the DC supply for the 4093 should be 5 Volts?.

I am very doubtful about some JLN's specifications.

For example, if you try to reproduce the very simple JLN's "negistor"
experiment, with a mere 12 volts bat, you will almost certainly fail!
see : http://jlnlabs.online.fr/cnr/images/negoscdg.gif
From (http://jlnlabs.online.fr/cnr/negosc.htm).

Why? Because the DC supply should be fine tuned and this is not specified.
Depending on the cap. and the coil it could be 8.6-8.8 volts or 10.1-10.5 volts
(for ex.)
I managed to get better results with different values.
This is off topic , but if you are interested in, some picture are on:
