Thanks Jan,
Yes it's a very nicely behaved coil. The 3 phase DC supply lets me get
multiple kW without upsetting the neighbours too much due to dimming lights
or surging, and the MOTs aren't overstressed much. I find it much more
user-friendly than my pig-powered single phase coil.
I have more info on my blog at www.gregsstuff.com if you're interested.
My VFD is similarly protected to yours, normally it runs fine but for some
reason it was playing up that night. I think I need to get it into a
grounded box. To be honest I normally run it at 50Hz anyway so I may just
hard wire it at some point.
Can I see your coil somewhere?
Cheers,
Greg
