A voltage control apparatus for an electric generator includes a load response controller and a voltage response controller. The electric generator includes a field winding and is driven by an engine of a motor vehicle. When the output voltage of the generator decreases below a threshold voltage upon the application of an electrical load, the rotational speed of the engine fluctuates to repeatedly increase and decrease until it is stabilized. During the time periods in which the rotational speed of the engine decreases, field current supplied to the field winding of the generator is gradually increased under a load response control performed by the load response controller. During the time periods in which the rotational speed of the engine increases, the field current is gradually increased under a voltage response control by the voltage response controller.
