| description | A control apparatus for an AC generator of a motor vehicle of high reliability having substantially no adverse influence to an onboard battery and an onboard high-voltage load by suppressing to a passible minimum variation of a regulating voltage which may occur as contacts of a detection voltage change-over switch are degraded. An AC generator of a motor vehicle includes a rectifier circuit for rectifying an output of the AC generator including a field coil, an output change-over switch for changing over an output of the rectifier circuit to either one of a battery and a high-voltage electric load mounted on the motor vehicle, and a voltage regulator for regulating an exciting current supplied to the field coil in dependence on a terminal voltage of the battery as detected on a charging line connected to the battery by way of the output change-over switch upon charging of the battery from the output of the rectifier circuit, to thereby regulate the output voltage of the AC generator. |
