A vehicle AC generator control device,
comprising: an AC generator (1) including
a field coil (102); a rectifier (2) for
rectifying an AC output of the AC
generator (1); a battery (4) connected to
an output terminal of the rectifier (2); a
voltage regulator (3) including a switching
element (305) series-connected to the
field coil (102), the voltage regulator
detecting a terminal voltage of the rectifier
or battery to operate the switching
element to control a field current of the
field coil to adjust an output voltage of the
generator to a predetermined value; a
dummy load unit (10) including a dummy
load (10d) balanced with an output
capacity of the AC generator (1); and an
overvoltage limiter (9) which detects when
the output voltage of the AC generator (1)
exceeds a set value, to energize the
dummy load unit (10), so that the dummy
load unit (10) is connected to an output
terminal of the rectifier (2), thereby to
suppress abnormal rise of the output
