Abstract
A method and apparatus for mitigating arc faults in a power generation system includes reducing and/or eliminating voltage when an arc is present, to protect the system from associated damage.
Claims15
A system for mitigating an electrical fault, the system comprising:
- a fault-tolerant power source having an output terminal connected to a load, said power source for providing regulated current to the load;
- a second system for detecting the electrical arc fault;
- and
- a switching device across the output terminal for reducing a potential difference at the output terminal upon detection of the electrical arc fault by the second system.

An apparatus for mitigating an electrical arc fault, the apparatus comprising:
- a fault-tolerant power generation apparatus for providing regulated current to an external circuitry, the means for providing having output means;
- an second apparatus for detecting the electrical arc fault within at least one of the power generation apparatus and external circuitry;
- and
- means for reducing a potential difference across the power generation apparatus upon detection of the electrical arc fault by the means for detecting.
