中文摘要: 中继线圈能有效增大磁耦合谐振式无线电能传输(MRC-WPT)系统的传输距离,但由于其自身的功率损耗,导致系统总损耗增加,传输功率下降。提出了一种有源中继结构,通过向中继线圈赋能,扩大了发射线圈的能量辐射范围,在显著增大系统传输距离的同时增大了系统的传输功率,保证了输出功率恒定。与多发射线圈系统相比,有源中继系统不需要考虑发射线圈之间的交叉耦合影响,分析及设计更加方便;与传统无源中继系统相比,有源中继系统的最大传输功率高于对应的无源中继系统;与对应的无中继系统相比,在增加传输距离的同时,有源中继系统的最大传输功率能保持与无中继系统相同。仿真结果与理论分析结果一致。

Abstract:The transmission distance of magnetic resonant coupling wireless power transfer (MRC-WPT) system can be significantly increased by placing intermediate coils between transmitter and receiver.While the loss of repeaters adds up the loss of the system,causing the decline of system transmission power.An efficient WPT system with active repeaters (ARs) is proposed.The power transmission distance and transmission power are improved and the output power is guaranteed to be constant by empowering the repeater.Compared with the multi-transmitting coil system,the active relay system does not need to consider the influence of cross-coupling between the transmitting coils,and the analysis and design are more convenient.Moreover,AR-based system can attain higher transmission power than the PR-based system.And compared with the non-repeater system,while increasing the transmission distance,AR-based system can attain the same maximum transmission power.Simulation results confirm the conclusions.
