Hey Luca
The 800A figure could we call my maximum safe point for short runs, ward ran 40N60 miniblocks at 1000A.
The MMC could use some funding, but I had to make a small one to start with because of the economics, I am considering going for a 6kV rated instead which will be 27 capacitors instead of 12 or possible go slighty down in capacity. 8kV would be 48 capacitors, its not cheap to go for a high capacity mmc :)

My father gives the secondary some varnish once in a while, I think its at 6 layers now.
The next thing is the toroid, it will be 120 mm aluminium ducting on a wooden form, using wall filler to get a even surface and covering it with aluminium tape.
Progress is somewhat slow as I am packing down all my stuff and moving to a new apartment, also my tube amp slash girlfriend have been taking a great deal of my attention :)

Very nice job! Are you still planning to use IXYS 60N60 IGBTs? I'm just curious to know how many amps you will be able to push through those devices...

Thanks :)
I will still be using the IXGN60N60C2D1 IGBTs, I will keep at a modest 500A to start with and try to push them later when I get a predikter driver on my hands
