小卫星电源管理模块的设计

Design of the Power Management Module for Micro-Satellite

小卫星在轨运行期间受重量、体积、环境等因素的限制,电源系统所携带的能源有限。为了提高能源利用率,本文提出在星务计算机中添加电源管理模块,将小卫星闲置的分系统成分置于低能耗状态的思想。给出了电源管理模块的电路和软件的具体设计方法。

Micro- satellite is limited by such factors as the weight, volume, environment, etc., so the energy that the power system carries is limited. In order to improve the energy utilization ratio, this paper proposes integrating a power management module in house -keeping computer to put subsystem composition the state to the low energy consumption. This paper also provides design method of the circuit and software of this power management module.
