摘　　要：用于卫星测试评估用的电源阵列模拟器应具备卫星帆板电源的电输出特性,能够模拟太阳能阵列的IV曲线。文章以此为背景,研究一种卫星帆板电源阵列模拟器。根据卫星帆板电源的物理模型建立IV曲线指数数学模型,采用XC6SLX16-2CSG225C作为整机IV模拟的控制FPGA,使用多路线性压控电流源电路并联实现整机功率调整输出,最后构建实际电路进行验证。验证结果表明:设计的模拟器性能指标高,设置曲线和模拟曲线一致性好。The power array simulator used for satellite test and evaluation should have the electrical output characteristics of the satellite panel power supply and be able to simulate the I-V curve of the solar array.Based on this background,this paper studies a satellite panel power array simulator.According to the physical model of the satellite panel power supply,the I-V curve exponential mathematical model is established.XC6SLX16-2CSG225C is adopted as the control FPGA of the whole machine's I-V simulation.The multi-route voltage-controlled current source circuit is used in parallel to realize the power adjustment output of the whole machine.The results show that the designed simulator has high performance index and good consistency between setting curve and simulation curve.
