摘　　要：随着3D打印等新技术的空间应用,新一代航天装备对能源系统的功率需求将日益增加。运行于低地球轨道航天器将面临低能高密度等离子体环境,导致高压太阳电池阵产生静电放电效应。通过模拟低轨道等离子体环境特点,测试了不同等离子体能量、密度以及电池偏置电压下高压太阳电池静电放电试验,揭示了等离子体参数对放电特性的影响规律。研究结果显示,当高压太阳电池的偏置电压达到-70 V时,静电放电现象开始显现,并且随着偏置电压幅值的增加,静电放电频次也相应增多。此外,空间等离子体的密度越大,越容易诱发静电放电,而轨道等离子体的能量对静电放电次数的影响则相对较小。The power demand of spacecraft energy systems will continue to increase with the application of new technologies such as 3D printing.When the spacecraft using high power energy systems runs in low earth orbit,it will be encountered a cold and viscous plasma in space,causing discharge effects in high-voltage solar cell arrays.This paper simulates the plasma environment in low earth orbit and tests discharge of high-voltage solar cell under different plasma energy,density,and battery bias voltage,revealing the influence of plasma parameters on discharge characteristics.The research results indicate that the discharge begins to occur when the bias voltage is-70 V,and the number of electrostatic discharges increases with the increase of bias voltage amplitude.At the same time,high-density plasmas are more likely to induce discharge,while the temperature of orbital plasmas has a smaller impact on discharge characteristics.
