中文摘要:
      线圈是无线输电系统中实现电磁耦合谐振的核心部件,具有高品质因数和均匀磁场的线圈是无线电能传输系统获得高传输效率和稳定输出的重要保证。基于磁谐振无线电能传输系统的基本结构和工作原理,总结了磁谐振无线输电系统中线圈的主要设计方法。首先介绍了常用的线圈类型和线圈尺寸的优化选择;然后对比了不同的线圈电感计算公式的适用范围;最后论述了线圈内阻、匝间距等参数对磁谐振无线输电系统传输效率和输出功率的影响。此工作对磁谐振无线电能传输系统的线圈优化设计有一定的指导意义。
英文摘要:
      Coils are the core part for realizing electromagnetic coupling resonance in a wireless power transfer(WPT) system, and the coil with a high-quality factor and a uniform magnetic field is important for guaranteeing the WPT system's high transfer efficiency and stable output. In this paper, the main design methods for coils in a magnetic resonant WPT system are summarized based on the basic structure and working principle of the magnetic resonant WPT system. First, the common coil types and the optimization of coil size are introduced. Then, the applicable ranges of formulas for calculating the inductance of different coil structures are compared. Finally, the effects of parameters such as internal resistance and pitch on the transfer efficiency and output power of the magnetic resonant WPT system are analyzed. The research in this paper is of certain guiding significance to the optimization and design of coils in a magnetic resonant WPT system.
