Patent ID: 8760094

Claim:
An apparatus comprising: a condition detector configured to identify a condition at an input to a power converter from an alternating current bus, wherein the alternating current bus receives alternating current power from a generator, the power converter converts the alternating current power on the alternating current bus to direct current power on a direct current bus, the direct current power on the direct current bus powers a load, and the condition is caused by at least one of the power converter, the direct current bus, or the load; and a breaker controller configured to disconnect the power converter from the alternating current bus in response to identifying the condition for at least a first time period, wherein the first time period is selected such that the breaker controller disconnects the power converter from the alternating current bus before the alternating current bus is disconnected from the generator due to the condition, determine whether the condition includes an unbalanced voltage condition on the alternating current bus, determine whether the unbalanced voltage condition is less than a threshold for more than a second time period, and reconnect the power converter to the alternating current bus in response to a determination that the unbalanced voltage condition is less than the threshold for more than the second time period.
