The invention relates to an unmanned aerial vehicle wireless power transmission technology, in particular to an output switching type continuous arch bridge type CPT system and a switching method, and the system comprises an unmanned aerial vehicle and a platform. The device further comprises a wireless electric energy transmitting module, a wireless electric energy receiving module and a coupling mechanism. The wireless electric energy transmitting module comprises a direct-current input power supply, a high-frequency inverter circuit and a transmitting side compensating circuit; the wireless electric energy receiving module comprises a receiving side compensating circuit, a rectifying circuit, a filter capacitor, a filter inductor and a load resistor; the coupling mechanism comprises a wireless electric energy transmitting pole plate, a wireless electric energy receiving pole plate and a coupling circuit. According to the system, not only is the cross coupling capacitance of the coupling mechanism extremely small, but also the coupling capacitance change of the transmitting polar plate and the receiving polar plate can be greatly reduced when the unmanned aerial vehicle has landing deviation, and constant-voltage and constant-current output switching can be realized on the premise of avoiding communication between the transmitting polar plate side and the receiving polar plate side.

    本发明涉及无人机无线电能传输技术,具体涉及一种输出切换型连续拱桥式CPT系统及切换方法,该系统包括无人机和平台;还包括无线电能发射模块、无线电能接收模块和耦合机构;无线电能发射模块包括直流输入电源、高频逆变电路、发射侧补偿电路;无线电能接收模块包括接收侧补偿电路、整流电路、滤波电容、滤波电感及负载电阻;耦合机构包括无线电能发射极板、无线电能接收极板和耦合电路。该系统不仅耦合机构交叉耦合电容极小,且在无人机发生降落偏差时,能够极大程度减小发射极板和接收极板耦合电容变化,并能在避免发射极板侧和接收极板侧通信的前提下,实现恒压恒流输出切换。
