<p>Prior power generation systems generated output voltages having relatively large, undesirable over-voltage transients due to sudden load reduction. In order to overcome this disadvantage, a power generation system for generating a DC bus voltage on a DC bus (14) is provided with a switch (80) coupled across the DC bus (14) to suppress over-voltage transients. The power generation system includes a synchronous generator (24) that generates AC power and a rectifier (54) that rectifies the AC power to produce DC power and supply the DC power to the DC bus (14). A voltage regulator (62) controls the magnitude of the DC bus voltage by varying the amount of current provided to a field winding (46) associated with the synchronous generator (24). A switch (80) is coupled across the DC bus (14) and is repeatedly switched when the DC bus voltage reaches a predetermined magnitude.</p> |
