Owing to initially rising characteristic, the series generator is often used as a voltage booster to give an increase of voltage practically proportional to the current.

A series generator also finds application in electric traction where 'dynamic braking' is employed. The connections of the series traction motors are changed by means of a controller so that they act as generators ; the power absorbed in braking the vehicle being dissipated in resistances, which are also used for starting purposes when the machines are reconnected as motors.
