Abstract :
This paper presents a photovoltaic (PV) module level DC-DC converter with an arc fault detector (AFD) and arc protection scheme for a DC distribution system. This module level approach improves system reliability by detecting arc faults and de-energizing only faulty part of the system. In addition, due to the ease of arc faults location and maintenance, system availability can be maximized. In addition, the proposed cooperation between protection devices is effective in device protection and safety guarantee. A prototype converter and experimental dc system setup validate its feasibility.
