摘要
A modular three-port converter-based spacecraft power system is analyzed. To achieve power management of the distributed power system, a novel hybrid power control strategy is proposed, that is, current sharing control on the battery port when the battery discharges and power distribution based on the ability of sources when the battery charges. With the proposed power control, reliable and stable operations of the system within all of the conditions can be achieved. The experimental results demonstrate the feasibility of the proposed power control strategy.
