Kapanadze Cousin - DALLY FREE ENERGY

[Hoppy]

Hoppy, thanks,   

snubber used is basically what i showed here:

http://www.overunity.com/12736/kapanadze-cousin-dally-free-energy/msg419485/#msg419485

changes compared to this are:

# NO schottky across source to drains (did not improve)
# MOSFETs are IRFP4668's
# 1n4007's are NOT reversed and are UF4007's
# C12 are 47nF

I have to sleep over your statement (from T1000) in red

Itsu,

Thanks for the listing of your snubber components. I tried 30V transorbs in series with fast diodes across each primary half winding and this does remove most of the leading edge spike for me. However, given that the circuit calls for high voltage components comprising the filter for the Karcher primary (assuming as Akula shows, it should be powered from the yoke secondary via a FWBR), I'm not sure that in this application its essential to snub out the spike to such a low level and thus dissipate appreciable heat in the snubber components . What is clearly important is to limit the spike to a safe level under the max voltage of the mosfets / IGBT's used.

  Itsu:
  Always a pleasure to see your work. Nice!!!
  One question. Did you connect the three turn coil's output to the 28 turn coil's output, (small jumper) and to earth ground, as shown in Ruslan"s diagram?
   Remember that without the earth ground to the coils, the circuit did not work properly for Ruslan.

Hi Nick,  thanks.

What small jumper are you refering too?  I do not see one:

Hi Guys
According to my experiments and understanding,
Inductor 25+25 is completely useless if you go to work with Katcher. I believe that this inductor was initially used to load the grenade with high freq. pulses which can be extracted from the yoke when you use acula's snubber. Inductor is not there for driving the grenade at the low KHz frequency. If you load it with the low frequency then the output is getting lower in terms of power, because the way it is winded opposes to the main current flow. If someone else experience the same results please share.

Tnks

Hi Enjoykin. Thanks for that.
Many of the people here can not speak Russian.
Any chance you can provide a short summary here of the important points in English?
All the best...
