航天器新型功率电源系统设计

Design of New Power Supply System for Spacecraft

摘要:

近年来航天器整体技术发展迅速,对电源系统的轻质小型化要求越来越高。传统的功率电源系统储能单元采用蓄电池组或贮备电池,由于脉冲类负载存在脉冲电流用电的工作特性,在储能单元设计时通常采用增加电池设计容量的方式来满足脉冲类负载供电要求,导致功率电源系统轻质小型化设计受到限制。本文提出一种新型功率电源系统方案设计思路,引入超级电容器与蓄电池组联合供电输出,充分发挥超级电容器大脉冲放电的优势,有利于实现航天器功率电源系统轻质小型化,具有一定的应用前景。

Abstract:

In recent years, the overall technology of spacecraft has developed rapidly, and the requirement for lightweight and miniaturization of power supply system is becoming higher and higher. The traditional energy storage unit of power supply system uses battery pack or disposable battery. Because of the working characteristics of pulse current, the design of energy storage unit usually uses the method of increasing the design capacity of battery to meet the demand of pulse load,
