Power routers enable flexible and efficient power conversion, significantly enhancing system efficiency and power supply reliability, which is critical for unmanned autonomous systems (UAS). A novel wireless power router is proposed in this paper by combining the advantages of wireless power transfer system and power router. It enables flexible access to multiple types of functional modules, meeting the operational requirements of various scenarios. A battery-friendly power management strategy is proposed to reduce the number of charge-discharge cycles. First, the system structure is presented along with descriptions of the control methods for each module. On this basis, A power management strategy is proposed to minimize the number of battery charge-discharge cycles. Experiment validated the effectiveness of the proposed structure and management strategy.
