Abstract
When a solar array in Low Earth Orbit has a high voltage of 100V or higher, an arc occurs. It causes surface degradation, electromagnetic interference and other undesired side-effects. Considering a large space platform of 1MW power in future, solar array which can operate at a voltage of 300V or higher is required. We report the results of experiments where we test the following three mitigation techniques to suppress the arcing; (1) Because an arcing is due to the charging of the coverglass by positive ions, we place PET (polyethyleneterephthalate) film in front of the coverglass to physically prevent the charging by ions. (2) We place conductive wire in front of the interconnector to narrow the plasma sheath region around the interconnector. (3) We use conductive ITO (Indium Tin Oxide) coating coverglass to reducing the charging on coverglass. The effect of each mitigation method is compared based on the tests in a vacuum chamber which simulates the plasma conditions in Low Earth Orbit.
