In a synchronous generator of brushless type where the field winding (2) of the rotor of the main device is fed via a co-rotating rectifier (8) from the rotor windings (4) in the rotor to a supply device on the same shaft, a damping resistance is put into the excitation current circuit, connected in parallel with a turn-off thyristor (10). With de-coupling of the excitation, the thyristor (10) is turned off by means of a turn-off pulse transmitted by means of a slip-ring arrangement (11, 12). |
