An automotive alternator is provided which includes a rectifier, a circulating circuit, and a controller. The circulating circuit is connected in parallel to a field winding to circulate the field current in the event that supply of the field current to a field winding is cut. The circulating circuit consists of a first circuit formed by a diode and a second circuit working to enhance attenuation of the field current. The controller works to select the second circuit when a voltage of the output of the rectifier exceeds a reference value and select the first circuit when the voltage of the output of the rectifier is less than the reference value.
