A synchronous machine has a frame, a shaft, a main section, and an exciter section. The main section has a stator winding which is mounted on the frame, and a rotor winding which is mounted on the shaft. The exciter section has a transformer and a rectifier. The transformer has a primary winding mounted on the frame and a secondary winding mounted on the shaft. The rectifier is mounted on the shaft and rectifies an output of the secondary winding to provide a rectified output to the rotor. A control unit provides a high-frequency control signal to the primary winding. This signal is magnetically coupled to the secondary winding, rectified, and then applied to the rotor to control the operation of the synchronous machine. |
