ARC fault protection for power conversion

A system for arc fault protection during power conversion, comprising:

• a first DC source;
• a second DC source;
• a power converter comprising:
• a first pair of DC input terminals coupled in series to a second pair of DC input terminals, wherein the first pair of DC input terminals are coupled to the first DC source and the second pair of DC input terminals are coupled to the second DC source;
• an input bridge coupled across the series combination of the first and the second pair of DC input terminals;
• and
• an inductor wherein a first terminal of the inductor is coupled between the first and the second pair of DC input terminals, and a second terminal of the inductor is coupled between switches on one leg of the input bridge;
• a first arc fault protection capacitor;
• and
• a second arc fault protection capacitor, wherein the first arc fault protection capacitor is coupled across the first pair of DC input terminals, and the second arc fault protection capacitor is coupled across the second pair of DC input terminals.
