Abstract
A system includes an excitation system configured to regulate one or more outputs of a power generating system. The excitation system includes a power conversion module (PCM). The PCM includes a direct current (DC) link, a plurality of insulated gate bipolar transistors (IGBTs) configured to generate an output to the system, and a nonlinear resistor configured to limit a voltage of the DC link to a predetermined threshold.
