METHOD OF DETECTION AND ISOLATION OF FAULTS WITHIN POWER CONVERSION AND DISTRIBUTION SYSTEMS

摘要

A power conversion and distribution system detects faults by monitoring differential current and differential power at certain locations in the system. Current loss faults are detected based on the monitored differential current, and series arc faults are detected based on the monitored differential power. A system controller 16 may make the fault determinations and disable a power converter circuit 12 of the power conversion and distribution system in response to detection of a fault.
