Abstract: To address the challenges of the conventional back-to-back railway energy router, which necessitates two sets of inverters leading to high capacity requirements and costs, this paper introduces a hybrid structure integrating an interphase bridging inverter with the conventional topology. Firstly, the operational principles and modes of the hybrid structure are analyzed. Subsequently, a power flow optimization control strategy is proposed to determine the active and reactive power of the hybrid structure railway energy router for different operational modes. Finally, the correctness and effectiveness of the proposed topology and control strategy are verified based on typical scenarios and measured data. In comparison to the conventional railway energy router, the novel topology offers distinct advantages. While retaining the functionality of recovering regenerative braking energy and accommodating photovoltaic, it also enhances power quality, resulting in a 21.2% reduction in both inverter and transformer capacities.
