ABSTRACT:
An electrical generation system comprising a generator. The generator including, a stator portion, and a rotor portion, and a variable frequency generator (VFG) exciter. The VFG exciter including, a first converter, operative to convert DC current to AC current connected to a DC link and a second converter, operative to convert DC current to AC current connected to the DC link. The system including a first switch operative, when closed, to connect the first converter to the stator portion while the generator is operating in a starting condition, wherein the first switch is open while the generator is operating in a running condition. The system including second switch operative, when closed, to connect the first converter and the second converter in parallel to the rotor portion while the generator is operating in a running condition, wherein the second switch is open while the generator is operating in the starting condition.
