Almost finished the torroids.
No1 (225v)is actually one which was all ready to go into another Madinverter.
That just needs the primary wire taken off and re done with 35mm2
No 1 needs 128 turns of 4 secondaries of 2mm2 and 25 turns of 1 35mm2 primary.
This is double stacked 3kw cores.
I did however manage to get a hold of some more 3kw toroids, so that one may still get put aside for another Madinverter and wind another identical one for the Warp unit (but different primary winding).
No2 (75v) is a 2kw core.
104 turns of 4 secondaries of 2mm2
61 turns of 13.5mm2 primary.
Klaus, I think you are doing something similar here, be warned it is a tight fit.
This is all I had left.
No3 (25v) is another 2kw core.
34 turns of 4 secondaries 2mm2.
60 turns of 2 primaries 2mm2
No4 (8.33v) Almost finished doing the primary.
1.5 kw core.
17 turns of 4 secondaries 2mm2
90 turns of 1 primary 2mm2.
Now onto the boards.
