Claim 0:
1. An exciter comprising:
a stator armature defining a plurality of circumferentially spaced apart winding slots separated by respective stator teeth;
a first exciter winding, wherein individual windings of the first exciter winding are seated in the winding slots;
a second exciter winding, wherein individual windings of the second exciter winding are seated in the winding slots; and
wherein for each phase of each of the first and second exciter windings there are two leads configured to connect to a generator control unit (GCU), wherein a main machine is electrically connected to a power bus through a main machine output line, wherein the generator control unit includes a power supply, a controller, and a converter, wherein the controller is configured to receive input from the main machine output line, wherein the controller is configured to switch between the first exciter winding and a second exciter winding for power conversion based on the input received from the main machine output line, wherein the first exciter winding is used at a first shaft speed and the second exciter winding is used at a second shaft speed, the first speed being different than the second speed.
