Document Type and Number:
Japanese Patent JP3359792
Kind Code:
B2
Abstract:
A control apparatus for an AC generator of a motor vehicle includes a rectifier (2) for rectifying a voltage generated by an AC generator (1) which is driven by an internal combustion engine and has a field coil (102), a battery (4) charged with electric energy outputted from the rectifier (2), a high-voltage electric load (5) of the motor vehicle supplied with electric energy from the output of the rectifier (2), a mode setting means (8) for changing over the output of the rectifier (2) to the battery (4) or the high-voltage electric load (5) of the motor vehicle to thereby set a battery charging operation mode or a high-voltage operation mode, and a voltage regulator (3A) for controlling a field current flowing through the field coil (102) so that the field current increases gradually at rate of changes set for the operation modes, respectively, to thereby regulate an output voltage of the AC generator (1) to a predetermined value in each of the operation modes as set. Engine rotation control can be performed with high accuracy and reliability regardless of variation in the load of the AC generator upon load change-over thereof.
