Series Generator Fig. (a) Circuit for loading a series generator. Fig. (b) Characteristic curves of a D. C. series generator. 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. | |
