Abstract
An arrangement including an AC generator,whose output voltage is regulated with a control quantity for a field current flowing through a field coil,of the AC generator, a switching element 308 for performing on/off-control of the field current flowing through the field coil,with a predetermined duty ratio, a voltage detecting means,for detecting an output voltage of the AC generator,and a gradually increasing control means,A for increasing gradually a conducting rate by increasing gradually the duty ratio in dependence on the detected output voltage, and a rotation speed detecting means,for detecting a rotation speed of the generator,wherein the gradually increasing control means,A is designed to increase the gradually increasing rate of the duty ratio in conformance with increasing of the rotation speed detected by the rotation speed detecting means
