The invention discloses a wireless electric energy transmission device for improving system interoperability and a control method. The device comprises a power factor correction circuit, an inverter circuit, a resonance unit, a rectification circuit, a filter circuit and a load which are sequentially cascaded, and also comprises a source side regulator, an inverter mode controller and a load side regulator. By switching the working modes of the inverter circuit and the rectifying circuit, with a bus voltage regulation and controllable rectifying technology, interoperation and high-efficiency electric energy transmission of the IPT system are realized, and multi-gear power level transmission requirements can be met in a wide load range and a wide coupling coefficient range. According to the invention, the interoperation requirements of three types of power levels and three types of energy transfer distances of EV WPT system vehicle-mounted end equipment are met by using one set of device, additional circuit elements do not need to be added in the aspect of circuit topology, the system cost and the installation space are effectively reduced, and the cost performance is high.

    本发明公开一种提升系统互操作性的无线电能传输装置与控制方法,装置包括依次级联的功率因数校正电路、逆变电路、谐振单元、整流电路、滤波电路与负载,还包括源侧调节器、逆变模式控制器与载侧调节器。本发明通过切换逆变电路与整流电路的工作模式,配合母线电压调节与可控整流技术,实现了IPT系统的互操作与高效率电能传输,能够在宽负载范围、宽耦合系数范围内满足多档功率等级传输需求。本发明用一套装置满足了EV WPT系统车载端设备的三类功率等级与三类传能距离的互操作需求,且在电路拓扑方面无需增加额外的电路元件,有效减小系统成本和安装空间,具有高性价比优势。
