摘要

提出了一种用于小卫星电源系统星载电源管理的统一三域控制单元。控制单元由几个自主自振荡MPPTs(最大功率点跟踪器)、CV(恒压)控制和CC(恒流)控制组成,用于给电池充电。所介绍的电路是为具有非稳压电源总线拓扑结构的高可靠性电源子系统而开发的。分布式和集中式电路的组合用于为电池充电和太阳能阵列电源管理提供有效的单点无故障解决方案。

Power subsystem for small satellites with unified operational mode controller
This paper presents a novel unified three domain control unit for onboard power management in small satellite power systems. The control unit consists of several autonomous auto-oscillating MPPTs (Maximum Power Point Tracker), a CV (Constant Voltage) control and a CC (Constant Current) control of charging the battery. The introduced circuits were developed for a high reliability power subsystem with unregulated power bus topology. A combination of distributed and centralized circuits are used to provide an efficient single point failure free solution for battery charging and solar array power management.
