Kapanadze Cousin - DALLY FREE ENERGY

  Nothing special?  But, it works, and Ruslan is not an experienced electronics hobbyist. Or is he?  AND, in such a short time? Think about it...
  Just my observation.

[John.K1]

There is a guy who does these electronical  thinks for him. Ruslan is gonna give him his first unit.

[NickZ]

  You're probably right. Maybe we should order some boards from that same guy, free shipping.  If we only knew who he is. 
Maybe it was Ruslan that got his first unit from that guy, instead.
   Time will tell... the race is on between Akula and Ruslan.

hi everyone,

I discovered the TC4420 or TC4452 series is not good at handling any voltage higher than 18volts eg:18.63volts.
Even the TC4451 driver at the nanosecond generator which was not even connected to output can be destroyed as well."Becomes unpredictable more than 18volts"

Hence i just used FOD3180 which is able to hande up to  20volts via LM7820 easily for the IGBT drivers."Can't seems to find my 7818 regulator"

Currently i have started playing with 30volts with 600volts IGBT.No issue detected so far.

For safety i was using small 2 pin "self-resettable circuit breaker" design to trip at 5Amps.This is my component life saver especially for IGBT's and wiring."Digikey"
This is used via (+) connection to center tap of toroid/yoke.

Hi Mag,

Use a 15V fixed reg or LM317 3-pin adjustable reg if you really need 18V.
