It's been covered before in this group and others, so search google
For example, a 5hp static converter will start a 5hp idler. Once it's
up to speed, the idler will use a few hundred watts (I think!) leaving
about 4.5hp available for a machine; the purity of the 3 phase will
probably decrease if you use more than 3hp of this. The other drawback
is when just the idler is going, you're back to the static converter
scenario but with insufficient loading, so it may get hot.
