Hi Greg et al
Look forward to that.
I've been looking for years to see somebody with 3 phase access use MOT's in
the manner you will be. It is a configuration just begging to be tried and
really cheaply done with free MOT's.
You will certainly obtain a stiff DC supply with very little ripple and no
big storage energy in a filter. I believe the MOT's will be fine and keeping
the DC filter cap small (if you use one at all) will greatly help the peak
current in the rectifier diodes small.
This design may be similar to my 6 MOT DC single phase 10kVA with resonant
charging although I have 3 MOTs in series per side centre tapped all driving
a FW bridge rectifier.
I assume you will use MOT's in the ring up inductor, I have done this with
success. I gapped them and set up an array of two in series and then
parallel two of these. Gapped to 0.3mm was what I used. simply put formica
sheet in the gap and glued it back together with builders wallboard
adhesive. (that brown cheap stuff). MOT's are deceptively easy to take the
E/I apart but removing the primary can be a little tough
Good luck

Hi Ted,
Thanks for your interest.
I'll upload some pics and specs of everything else over the weekend.
The supply transformers, MMC, secondary and primary are done.
I'm basically hoping to use two 2.4kV mots in series per phase (not
centre tapped). This should give me almost 24kV in the primary cap
with resonant charging.
Not sure how the MOTs will perform in this role but my fingers are crossed!
Cheers,
Greg.
