The invention provides a composite SAR satellite power supply system, which is provided with a single group of lithium ion storage batteries, and a discharge converter is additionally arranged between double buses, so that when the energy supply of a full-adjustment bus is insufficient, the full-adjustment bus is not adjusted, and the discharge converter provides energy for a full-adjustment bus load; on the basis, an efficient high-power filter is added to eliminate the influence on the input of the discharge converter due to the fact that bus pulsation is not adjusted due to pulse load work, and the reliability and safety of a satellite power supply system are further improved.
本发明提出了一种复合式SAR卫星电源系统,配置单组锂离子蓄电池,通过在双母线之间加入放电变换器,实现全调节母线能量供应不足时不调节母线通过放电变换器为全调节母线负载提供能量需求;在此基础上,通过加入高效大功率滤波器来消除由于脉冲负载工作而导致的不调节母线脉动对放电变换器输入的影响,进一步提高卫星供电系统的可靠性和安全性。
