中文摘要:
      针对目前应用在感应耦合电能传输(Inductive coupling power Transfer,ICPT)系统中数据传输技术的传输速率低、系统电路复杂等问题,论文提出一种基于部分能量线圈和正交频分复用(OFDM)技术的ICPT系统高速数据传输方案。该方案利用能量耦合线圈的一部分来构建高速数据传输通道,使得主要的电路拓扑具有带通滤波器的特性,并且数据传输通道对信号载波呈现低阻抗特性,对电能载波呈现高阻抗特性,从而减小了电能载波对信号载波的影响;采用OFDM技术提高数据载波频带利用率及抗干扰性,实现高速数据传输。实验结果验证了系统在保证电能传输不受影响的同时实现了高达10Mbps的数据传输速率。
英文摘要:
      Aiming at the problems such as low transmission rate and complex system circuit in data transmission technology in Inductive coupling power Transfer (ICPT) system, this paper presents a new method based on partial energy coupling coil and orthogonal frequency division multiplexing (OFDM) technology of ICPT system high-speed data transmission program. This scheme uses a part of the energy coupled coil to construct a high-speed data transmission channel, which makes the main circuit topology has the characteristics of the bandpass filter. The data transmission channel presents a low impedance characteristic to the signal carrier, but it presents a high impedance characteristic to the power carrier, which reduces the influence of the power carrier on the signal carrier; Adopts OFDM technology to improve the data carrier frequency utilization and anti-jamming, and realized high-speed data transmission. The experimental results have verified that the system achieves data transfer rates of up to 10Mbps while ensuring that the power transmission is not affected.
