Abstract
A generator driving apparatus is provided with a thyristor driving device for driving a motor-generator, and the thyristor driving device always controls the driving of the motor-generator regardless of the number of rotations thereof. Also, when the motor-generator is coming to a stop, energy conserved in the motor-generator is regenerated to an electric power system through the thyristor driving device.
