Abstract
A synchronous generator usable in both a starting mode of operation and a generating mode of operation includes a permanent magnet generator having a permanent magnet and an armature winding rotatable with respect to the permanent magnet, an exciter portion having an exciter armature winding and an exciter field winding rotatable with respect to the exciter armature winding, and a main generator portion having a main generator armature winding and a main generator field winding rotatable with respect to the main generator armature winding. An inverter is coupled to supply power to the main generator portion armature winding via a DC link during the starting mode of operation, and a controller is coupled to the DC link for controlling the magnitude of the DC link current provided to the inverter during the starting mode of operation.
