My 12kW powerjack build - Ozinverter Inspiration!
influence:
Perhaps I can remove a turn or two from the secondary to reduce the ratio?
oztules:
Sorry, I meant the secondary.... not thinking straight. If we wind for say 260v not 240v, then only use 240v, we are using lower flux, so lower iron losses... so more on the primary and secondary equally ( by ratio that is )

influence:
Ok noted. Btw does it matter which side of the primary the choke is on?
oztules:
No...

Had a seriously productive weekend...
I have used a ferrite transformer calculator and figured out the suitable turns for my choke (18 - 20 uH).
I ended up using an E70 N27 core from RS.
I did a calc for the 3.5 turns it came to about 0.5mm gap
However at 70mm2 cable I cannot fit 3.5 turns.
So I went with 0.2mm gap with 2.5 turns. It *just* fit.
