CLOSE. But, ... Remove the diodes completely from an
alternator.
Select
pulleys for correct ratio, and simply maintain a steady
engine speed to
provide 3600 RPM at the alternator shaft. Now you have 60Hz 3 phase
power. Adjust the voltage, and run minis and mainframes.
You'll need to drive where there is little traffic to maintain that
constant engine speed.
leave the diodes in and don't use them, bring out the power on leads
from the other side of the diodes for AC. the
rectified power can then
be used for reedback regulation of the AC. did this years
ago for
a ~1kw tube TX worked very well. it was cheaper than buying a
HV alternator (120/230v).
the auto system if well maintained can do just fine power wise.
resonable power is around 3-500W at the high side.
