A Kapanadze generator replication - Febuary 2013

Hi Grumage and Zcsaba ; yes as gyulasun said ZVS schematic is on the net if you google. This driver is very wild and deadly too cause it can pump alot of ma in a 1inch or more arc so if you're planning to build this be aware of it.
Today I remembered the setup I did last time as shown but changed cap to a 2500v smaller cap.
Another thing how can one do multi quote on this forum?
Still nothing OU yet cause I lit a 25w bulb I think same as input now.

Hi Guruji

Driver (ZVS+FB?) itself is deadly or whole stuff deadly?
I dont know how others does multi quotes, I open multi page and I copy from one to second. I hope this help for you

...  this video is on ZVS: http://www.youtube.com/watch?v=0ONq3DxXE2w  ...

This video looks like circuit diagram about induction heater , if am I correct.
This type circuit is ZVS?

It is an oscillator built around a line output transformer and the high voltage appears across the right hand side coil where a 13 kOhm resistor is shown as the load in the simulator.  The tank circuit is formed by the 5 + 5 turns of windings with the capacitor between the two drain pins of the FETs.
Probably the circuit could be used as an induction heater (if some changes are made in it to that direction with some additions too) but the original goal was probably to design a high efficiency high voltage energy source capable of giving strong output currents.
Yes this is a ZVS type circuit.  An off the shelf line output transformer always includes a (rectified) HV output, see the bell shaped insulation cap here http://wiki.4hv.org/index.php/File:DCFBT.JPG   The circuit shown in the video simulation is here too:

In one of the posts King said to crush ferrites and do a form you need; did you do this? Do you use special type of glue?

I think liquid epoxy should be fine.

Yes Zcsaba you're right whole stuff I think is deadly cause it gives greater current.
Posting thie ZVS schematic.
Ok thanks regarding multi quote.

.... still unopenable this pic or site. Can you post/attach here.
