Claim:
1. A direct current (DC) power generation system for reducing peak fault output current, the DC power generation system comprising: a generator configured to generate an alternating current (AC) power output in response to an excitation, wherein the generator includes a plurality of rotor poles and each rotor pole includes a corresponding damper winding, wherein each damper winding includes a plurality of damper bars secured to the corresponding rotor pole by a pair of end rings, wherein each end ring comprises at least two end ring mounts electrically isolated from each other and wherein each end ring mount secures at least one damper winding to the corresponding rotor pole; a rectifier array configured to convert the AC power output to a DC power output in response to a control signal; and a controller electrically coupled to rectifier array to control operation of the rectifier array, wherein the controller is configured to generate the control signal based on an oscillation component of the DC power output.
