摘要
PCB线圈由于其独特的优点,已广泛应用于磁谐振无线电能传输领域。系统在近距离传输时,其传输效率会急剧下降。针对此问题,本文采用一种有效的方法来改善其近距离传输效率。本文首先分析反并联线圈的工作原理,接着给出线圈各参数的计算公式,然后对四线圈结构的磁谐振系统建模分析。最后经实验验证该方法是可行的,为近距离磁谐振无线电能传输系统设计提供参考。
PCB coils with unique advantages, which is widely used in magnetic resonant wireless power transmission. when the transfer distance of system is short, which leads to a sharp decline in the efficiency. Aiming at this problem, this paper presents an effective method to improve the short distance transfer efficiency. Firstly, this paper analyses the work principle of antiparallel coil, then provides the calculation formulas of the parameters of the coil, and then analyses magnetic resonant system of the four coils structure. Finally, experimental results show the method is feasible, which can provide a reference for the design of short distance magnetic resonant wireless power transfer technology.
