I'm still not clear on this. 50 years ago when the USAF taught me
electronics there was only a brief discussion of reactive power where
current is stored and then released out-of-phase. That was fairly
straightforward. I don't recall any mention of THD (at least in relation to
power lines) so I don't have a good grasp of the issues with SMPS. And, it's
not clear to me whether PF as it relates to CFL/LED incorporates THD.

You and Don (and Cummins) seem to be saying that low PF adds to the
generator load but the increased load is not linearly proportional to PF.
How is this calculated?
