中文摘要:
      针对目前应用在感应耦合电能传输ICPT(inductive coupling power transfer)系统中数据传输技术的传输速率低、系统电路复杂等问题,提出一种基于部分能量线圈和正交频分复用OFDM(orthogonal frequency division multiplexing)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10 Mbps的数据传输速率。
英文摘要:
      Considering the problems in the data transmission technology for an inductive coupling power transfer(ICPT) system such as low transmission rate and complex system circuit, a novel method for the high-speed data transmission scheme of the ICPT system is proposed based on partial energy coil and the orthogonal frequency division multiplexing(OFDM) technology. This scheme uses one part of the energy coupled coil to construct a high-speed data transmission channel, thus making the main circuit topology has the characteristics of a bandpass filter. In addition, the data transmission channel presents low-impedance characteristics to a signal carrier but high-impedance characteristic to a power carrier, which reduces the influences of the power carrier on the signal carrier. The OFDM technology is adopted to improve the data carrier frequency utilization rate and anti-jamming, thus realizing the high-speed data transmission. Experimental results verified that the system achieved a data transmission rate of up to 10 Mbps while ensuring that the power transmission was not affected.
