Maybe YOU are talking about an RPC, but the subject of the OP is " VFD
question "

It operates at line voltage, and in Gunner's case at a constant 60 Hz.


It does matter, a set of transformers can most certainly come after a
RPC, if you only have buck transformers large enough to handle the three
phase current, not the single phase current.


* *Why would you put three after the RPC when one at the input ddoes it
right? *Are you that stupid?


I'm not stupid, but you may be if you are that clueless as to the
context and the point I made about the transformer sizing. If you have
for example three 1KVA transformers on hand but no 3KVA transformers,
it's a pretty easy choice to use the three you have downstream rather
than buy a new transformer to use upstream.


* *OK, if a hack job pleases you.

You can't fix stupid. You can't even put a Band-Aid™ on it, because it's
Teflon coated.


Remember ......... This multiple transformer idea was in response to a
VFD Question.
A VFD Question ... GET IT?

The original question was about a VFD.
The response was to add transformers to the output.

Do not expect to make it into a sensible discussion. It will not
happen.
