Most car alts here in the USA are actually 110Vac rectified to 13Vdc. You can certainly remove the rectifier, run the alt at high-idle engine speeds (1500RPM) and get 110vac out. IF I remember , it's 3-phase too. I did this years ago , just to see if it could be done. Worked "OK" lit incandescent bulbs easy enough.
BUT with it being 3-phase you should be able to get 220Vac out easy enough.
Go digging into the alt for the rectifier, find the 3 wires from the stator, put a meter on it.
Hope this helps
