3 Phase Converter Schematic. (Miller system)

The thread starter took the information from that site, a non electronic site and put his name to it(miller system) thinking no one would know. But he didn't count on someone that was a machinist with a small home shop and being interested in electronics being on both sites.
 
Well I finally finished going thru that thread. Looong time lol. I found several schematics that I will look at further while offline. Thanks again for steering me there.
I also figured out that CNC RPC's are probably just oversized/heavier built, which is helpful since I am dealing with a machine that has 2 VFDs in it.

Any thing over 5 or 10 horsepower needs a much bigger motor for the convertor. But one good thing about a rotary convertor is each motor you drive from it you get a better sine wave out, closer to real 3PH. So that will make your VFDs happier.
