Our task is to examine the effects of conductive current generated by arcing on solar array circuit of spacecraft. First, equivalent circuits of small solar array module are modeled. The equivalent circuits are made for various types of solar cells such as silicon, gallium arsenic (hetero-junction), and triple junction cells, etc. The equivalent circuit is composed of current source, diode, resistance, inductance and capacitance. First, we measured the frequency characteristic and I-V characteristic of a given solar array, and modeled the equivalent circuit to have the same characteristics by electronic circuit simulation software (SPICE). Next, an electric equivalent circuit of the arc inception was made, and was compared with the ground test result. We simulated the transient current and surge voltage resulted from the ground test using the equivalent circuit. The circuit is being adjusted to experimental results at present. We plan to add the effect of arc expansion to the circuit., 資料番号: AA0049206068, レポート番号: JAXA-SP-05-001E}, pages = {611--618}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Circuit analysis of effects of solar array arcing on spacecraft power system}, volume = {JAXA-SP-05-001E}, year = {2005} }
