Here is a shot of a cheapo £15.00 incl postage Chinese 24V/10A switched-mode PSU with just one blue cap (indicated with red arrow) needing to be removed to free the input from mains earth. This has both 220V and 110V switched input settings. The bridge rectifier (next to cap) is also easy to clip-out and replace with fast diodes if required.

   Hoppy:
  What a steal!!! Including shipping it to UK, wow. Makes me wonder, again, why not just buy the ready made induction heater/cooker circuit as well, with the adjustable controls, instead of making our own.  Seams like a waist of time to make these circuits... at least it does to me, when the Chinese are making circuits cheaper that we can even buy the parts for.  And the time it take to make them work, as well.
  Each new circuit that Ruslan is showing lately, looks more and more like a commercially made unit. Or not? 
  I know that it's just a matter of time before someone finds that commercially available circuits can be adapted for our purpose.   Mark my words...

Nick,

This PSU is shipped in the UK from a Chinese importer. No need to import nowadays, plenty of Chinese businesses over here! Hopefully, it will stay smoke free for a while.  ;D

Thanks Hoppy,

no need to replace the bridge rectifier as we suppose to run with 240V dc which will pass throught this FWBR.

    I wish that I could say the same, as I can't even get the new fets I need to continue on, here in C.R.  But, they are ordered and will be here, any month now, coming by turtle shipping, from China.

  Reminds me of the first page of this thread, where two computer PSU were fried, before finding one that finally worked. If I remember correctly, as it's been a while now.
  I wonder if the PC type of PSU might work for us, as well. But, I wouldn't want  to see them go up in smoke though.

As you rightly say, no FWBR replacement necessary. At the moment, I'm measuring 85V in with 11V out with a 12V / 20W halogen lamp as load and no additional load on the device output. So, a fair way to go yet!

These cheapo PSU's are pretty much shite but can be OK if not worked too hard. Mains input voltage surges are a common cause of premature failure, so unlikely to be a problem in our application.

Thanks, PSU bought :)

One more think somebody might know here. I did a surgery to several Microwave oven  caps. I removed 10MOhm resistors and I am thinking to use it in this device + their diodes.  The caps are 1.0 uF @ 2100V AC. Your opinion?- are they suitable??

  Sorry for the blurry pic. But, it seams to me that Ruslan is not making this PCB circuit. Nor is Akula, making his, nor was Kapandze's really making the aquarium device. So,... again, I wonder who is behind all these self runners?

Any experienced electronics hobbyist could produce a board like this at home. Nothing special here.

  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.

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

  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.
