摘　　要：耦合电感作为无线能量传输(WPT)中最常用的传输媒介,不仅可用来传输能量,也可用来传输信息。本文研究了利用耦合电感同时传输信息和能量(SWIPT)时的误码率、能量传输效率及系统各参数对性能的影响,优化了系统参数,并且比较了ASK和EBPSK调制信号用于该携能通信系统时的性能。仿真结果表明,基于耦合电感的携能通信系统能够同时做到误码率接近0,效率达到84%。Coupled inductor is the most commonly used transmission medium of Wireless Power Transmission (WPT) system;it can be used to transmit not only energy, but also information. This paper studied the Simultaneous Wireless Information and Power Transmit (SWIPT) system based on coupled inductor and showed the effect of different parameters on the performance of system, including the performance of bit error rate and power transmission efficiency. This paper also compared the performance of the SWIPT system using the different modulations of ASK and EBPSK. The simulation results showed that the bit error rate of the SWIPT system can be closed to 0, and the efficiency can reach 84%.
