为了解决微型胃肠道胶囊机器人或其他可植入医疗设备无法使用电源线供电以及无线能量发射系统性能差的问题,本文提出了一种新的U型发射线圈无线能量传输系统。与传统的螺线管对式的发射线圈相比,通过结构的改进,首次将磁芯加入到了发射线圈中。该系统可以极大地改善传输过程中传输效率低,机器人接收功率低的问题。本文建立了所提出的U型发射线圈无线能量传输系统的理论模型,并通过有限元模拟对其进行了分析。搭建了U型发射线圈无线能量传输系统平台对其能量传输效率和接收线圈的接收功率进行了测试,以验证所提出设计的有效性。实验结果表明,所提出的U型无线能量传输系统的传输效率最高达到14.13%,接收功率最高为3 780.75 mW,能够满足机器人工作的功率要求。
Power cables cannot be used to power micro gastrointestinal capsule robots or other implantable medical equipment, and wireless power transfer systems exhibit poor performance. To address these limitations, this paper proposes a U-shaped transmitting coil wireless power transfer (WPT) system. In contrast to the traditional solenoid-paired transmitting coil, the proposed transmitter coil comprises a magnetic core, which was added after incorporating a few structural improvements. The core can tremendously improve the power transfer efficiency (PTE) and received power. In this study, a theoretical model of the proposed system is established and analyzed via a finite element simulation. To verify the effectiveness of the proposed design, a U-shaped transmitting coil WPT system platform is built, and experimental tests on the PTE of the system and the received power of the receiving coil are conducted. The experimental results demonstrate that the maximum received power of the proposed system is 3780.75 mW and its PTE is 14.13%, which satisfy the power requirements of the robot.
