The invention provides a self-pickup type dynamic wireless charging system, and the system comprises a transmitting coil which converts high-frequency alternating current into alternating electromagnetic field energy and transmits the alternating electromagnetic field energy; the receiving coil receives the alternating electromagnetic field energy and converts the alternating electromagnetic field energy into high-frequency alternating current; when the transmitting coil and the receiving coil are located at opposite positions, equivalent self-inductance parameters of the transmitting coil meet electrical parameters required by ideal resonance of the resonance topology, and the transmitting coil and the transmitting compensation circuit are in a resonance state. The method has the beneficial effects that accurate and rapid identification and automatic tracking of the position of the load end can be realized without an additional device, and the investment cost is reduced; a switch and a corresponding control algorithm program do not need to be switched, self-adaptive power adjustment of multiple transmitting ends is realized, and the transmission performance of the system is ensured; in the power adjusting process of the transmitting unit, the total power of the system is not greatly changed, the impact on the system is small, and the stability of the wireless power transmission system is improved.

    本发明提供了一种自拾取式动态无线充电系统,包括:发射线圈,所述发射线圈将高频交流电转换为交变电磁场能发送;接收线圈,所述接收线圈接收交变电磁场能转换为高频交流电;发射线圈与接收线圈处于正对位置时,发射线圈等效自感参数满足谐振拓扑理想谐振所需电气参数,发射线圈与发射补偿电路处于谐振状态。本发明有益效果:不需要额外的装置实现负载端位置的准确快速识别和自动跟踪,降低了投资成本;无需切换开关和相应控制算法程序,实现多发射端的功率自适应调节,保证系统传输性能;在发射单元功率调节过程中,系统总功率变动不大,对系统的冲击小,提升了无线电能传输系统的稳定性。
