摘要:

谐振波束充电(RBC)可以通过谐振波束实现从发射器到多个接收器的无线功率传输(WPT)。自适应红细胞(ARBC)可以有效地提高其能量利用率。为了在ARBC系统中支持多用户WPT,提出了时分多址接入(TDMA)方式,并设计了基于TDMA的WPT调度算法。TDMA WPT方法具有并发充电、连续充电电流、单个用户功率控制、恒定驱动功率和灵活的驱动功率控制等特点。仿真结果表明,TDMA调度算法具有很高的效率,因为总的收费时间大约是替代调度算法的一半(46.9%时,收费50个接收机)。此外,WPT的TDMA启发了增强ARBC系统的思想,如流量控制和服务质量(QoS)。

英文摘要:

Resonant beam charging (RBC) can realize wireless power transfer (WPT) from a transmitter to multiple receivers via resonant beams. The adaptive RBC (ARBC) can effectively improve its energy utilization. In order to support multi-user WPT in the ARBC system, we propose the time-division multiple access (TDMA) method and design the TDMA-based WPT scheduling algorithm. Our TDMA WPT method has the features of concurrently charging, continuous charging current, individual user power control, constant driving power and flexible driving power control. The simulation shows that the TDMA scheduling algorithm has high efficiency, as the total charging time is roughly half (46.9% when charging 50 receivers) of that of the alternative scheduling algorithm. Furthermore, the TDMA for WPT inspires the ideas of enhancing the ARBC system, such as flow control and quality of service (QoS).
