Abstract
In a control apparatus of a vehicle AC generator, a flip-flop for receiving a clock pulse with a constant period and a control pulse is used. The clock pulse sets the control period at the constant period, and decides an on timing of the power transistor in this control period. The control pulse decides an off timing. A load response control circuit performs a load response control to adjust an on time ratio of the power transistor from a lower limit to an upper limit in accordance with an increase in load, and a second control signal circuit adjusts the on time ratio from a regulated value close to the upper limit to the upper limit.
