摘　　要：设计的无线充电动态谐振补偿装置,基于磁芯正交磁化的原理,通过对装置输入不同的控制电流,改变装置的电感量,使得耦合谐振式无线电能传输系统始终保持谐振状态,稳定系统的电能传输效率。通过实验分析,本装置可以有效克服主次线圈相对位置和变化负载对系统的影响,降低控制成本,提高无线充电系统实用性。This paper mainly focus on the design of a dynamic resonance compensating device, which is based on the orthogonal magnetic core. By changing the inductance value of the device through different current input, the wireless charging system can be kept at the resonant state and maintain power transmission efficiency of the system. According to the experiment analysis, the device can effectively overcome the influence of the relative position between the primary and secondary coil, as well as the influence of load changing.
