Hah, 150V? try 120V. Most of the MOTs ive played with start
saturating at about 90VAC input. They typically have a power factor
of .12 at full input voltage, though this was with an open circuit on
the HV secondary. I think the PF might have gotten up to .4 or so
with a heavy load... still junk in my opinion. I guess im lucky
enough to know how to use silicon (IGBTs) and ferrite to make my HV
transformers... 6kVA at about 10 lbs ;-) and no, they dont saturate.
