摘要：
A smart power flow node (SPFN) aimed at a hybrid ac/dc electric power system (EPS) for future more electric aircraft is presented. The SPFN is researched to enhance the performance of the EPS. Based on the SPFN, new power flow paths are established for the EPS, and intelligent power flow management of the EPS is realised. A multi-port topology is designed for the SPFN to be compatible with different ac and dc power ports. Moreover, three operating modes of the SPFN are studied to realise uninterrupted power supply, power support of high-power load and power transfer of the feedback energy from regenerative load. The experimental results verify the feasibility and availability of the SPFN and show that the SPFN can improve the equivalent capacity as well as the power supply reliability of the EPS.
