When the rectified output of an AC generator is changed over to a charging battery or a vehicle electric load, the value of exciting current to be supplied to the AC generator is controlled for the object for changing-over with a simple arrangement. If the rectified output of the AC generator 1A is changed over to the battery 4 to be charged by the output change-over switch 71, a voltage regulator 3A regulates the exciting current flowing through the field coil 102 of the AC generator 1A by detecting the terminal voltage of the battery 4. If the rectified output of the AC generator 1A is changed over to the vehicle electric load 5, the voltage regulator 3A regulates the exciting current flowing through the field coil 102 of the AC generator 1A by detecting the voltage at the positive terminal 201 of the rectifier 2.
