and boy was he right. (apologies to many for not re-emphasizing the subject: line in the message text, 50Hz is the goal)
Some UPS-like equipment will do this - stuff designed for running computer equipment in a field in the middle of nowhere, normally for pseudo military use; take any Generator input (which can be 30Hz-70Hz), any input voltage, normally close to sawtooth or triangle wave and covered with crap and artefacts, turn it into DC, put it into a few lead-acid batteries, and then work with the back-end of a conventional UPS.
yup, that seems to be the general approach. i have leads on a 220/50 ups of this type, and plan to feed it 220/60. but, as you say, feeding it 110/60 might work. randy
