#4 Put "Something" between outlet and SmartUPS when on generator
power. Such as:

A) AC -> DC -> AC converter (wow redundant)
B) Transformer -> 60hz LC tank circuit -> Transformer
C) magic pixie dust.

So any other thoughts?

D) Ferroresonant tansformer, a la Sola constant-voltage transformer?

With a changing frequency, that won't work.

E) Mag-amp

Mag-Amp, as in Magnetic Amplifier? While this is my first exposure to
them (and from my research, they are pretty clever devices!) I don't
see how I'm going to fix the frequency variation with a Mag Amp......
(unless I feed the Mag amp a seperate 60hz control signal..)


You can shift phase with a magnetic amplifier. Varying the phase can
correct for frequency modulations shifts that are smallish.


F) MG set with fly wheel

Hmm, I didn't think they actually made such a thing Till I googled for
it. :)

Assuming a 60hz in - 60hz out MG set, will it filter the frequency
domain if its all running on a common shaft (even with external
flywheel?)

The flywheel supresses short term variation in frequency. The more
massive it is, the longer "short term" means.



I need to work up the courage to put together a voltage divider and
plug my sound card into my wall outlet and digitize the generator
ouput error so I can actually measure how bad it is under a heavy
load... Hmmmmm
