摘要:
 摘要:应用集总参数和藕合模理论,研究了电磁耦合式无线电能传输系统的传输效率问题,提出
了使无线电能传偷系统传输效率最大的传输效率最佳频率概念,分析了传输系统参数和负载对传
输效率最佳频率和传输效率的影响。制作了两线圈无线电能传输实验电路,并进行了谐振频率与
输偷效率的关系,负载与传输效率最佳频率及传输效率的关系,距离与传输效率最佳频率及传输效
率的关系实验和仿真分析。实验和仿真分析证明了:无线电能传输系统有一个传输效率最佳频率;
传输效率最佳频率近似与负载成正比,与线圈的互感成反比;传输效率最佳频率随距离增加而增大;
当系统工作在传输效率最佳频率且负载电阻远大于线圈电阻时,无线电能传输系统的传输效率最大。
Abstract:
 Abstract:By applying lumped parameter circuit theory and coupled mode theory,the efficiency of wire-
less power transfer system via magnetic resonant coupling was researched,and the concept of transfer effi-
ciency maximum frequency was proposed when transfer efficiency is maximum. Influence of system pa-
rameters and load on transfer efficiency maximum frequency and transfer efficiency were analyzed. Two
coils transfer system was set up,and the relationship between the frequency and transfer efficiency,the
relationship between load and transfer efficiency maximum frequency and between load and transfer effi-
ciency were studied,and the relationship between distance and transfer efficiency maximum frequency and
between distance and transfer efficiency were carried out. Experiments and simulation prove that:there is
a transfer efficiency maximum frequency in wireless power transfer system;and this transfer efficiency
maximum frequency is proportional to the load and inversely proportional to mutual inductance approxi-
mutely;transfer efficiency maximum frequency increases with the increase of distance;when the system
work in transfer efficiency maximum frequency and the load resistance is much greater than the coil resist-
ance,the transfer efficiency of wireless power transfer system is maximum.
