| 摘 要： | 磁耦合谐振无线电能传输(MCR-WPT)系统功率传输效率随传输距离变化而迅速下降。为此,根据四线圈MCR-WPT系统电感耦合模型,推导出传输效率的数学计算式,以此提出利用不同半径的谐振器耦合线圈来匹配不同传输距离,并利用微控制器自动切换对应的谐振器耦合线圈。为验证设计方法的有效性进行仿真和实验分析,结果表明,这种方法可以使系统能量传输效率在较宽的距离区间内维持高效的水平。

| Abstract: | The energy transmission efficiency of MCR-WPT system declines with the variation of distance rapidly. For that, the Mathematical formula of coupling coefficient is derived from the inductive model of the four-coil MCR-WPT System. Using different diameter coupling coil to match different energy transfer distances is proposed. It switches to the corresponding resonator coupling coil automatically by using with MCU. To verify the validity of the method, simulation and experiment are analyzed. The results show that it can keep high energy transfer efficiency of the system in a wide range of distance. |
