transformer source

I am making a pedal charger for a 12v 3 ah battery using a ceiling fan generator making over 150vac. I assume current would be improved if a transformer limits the voltage? If so, I need a source for a 220vac to 18vac transformer. Mouser does not seem to stock this. Is there a salvageable alternative?

hi,

Think you will find Mouser do stock such transformers - look for ones that have 220 or 230v primaries or dual 115v which can be wired as 230v.
The 10v difference is negligable.

18v outputs are available , again some with dual taps as 9-0-9 or as part of a multitap output.
