I have been having some difficulty with a Tree CNC machine, and in the process of sorting that out, a question crossed my mind:
Can a VFD be used as a power smoothing/balancing device for the output of a whole-shop RPC?
I have a 10HP phase converter operating in my one-man shop. It is supplied with 240V single phase, and its output results in 241/241+/267V measured between the legs. In wrangling the issues of the Tree machine, which I think has a bad input circuit breaker, I wondered if using a VFD downstream of the RPC would allow for "tuning" of each leg of the 3-phase output from the RPC, to get closer to factory spec 230V +/- 5% on each leg. This is sort of a thought question from a theoretical standpoint. Obviously, if I were to be considering a VFD that could handle the shop needs, I wouldn't need the RPC in any case. I mostly want to know if the VFDs these days have this sort of voltage adjustment between legs, for a 3-phase to 3-phase unit.
