摘要：
In view of the complex circuit on the receiving side and the large volume of compensation inductance on the transmitting side of wireless charging system (WCS), a strong coupling WCS using LCC/N magnetic integrated compensation network and for being used in short distance condition is proposed in this paper. The LCC/N magnetic integrated topology combines both the advantages of no compensation circuit at receiving side and compensation inductor magnetic integration at transmitting side to make the WCS more compact and improve its coil offset performance. Firstly, the model for WCS is established with consideration of the cross-coupling relationship between the LCC/N magnetic integrated topology and the receiver coil. Then, the output power, transmission efficiency and zero-voltage-switch characteristics of the WCS with LCC/N magnetic integrated topology are analyzed under the condition of different loads and offsets. Finally, a 500 W experimental platform is built to verify the results of above analysis. The results show that when the coil offset is along y direction, the output power of system with LCC/N magnetic integration topology is higher than that of system with traditional non-magnetic integrated topology, thus its offset performance is improved. In addition, the adoption of LCC / N magnetic integrated topology can also achieve the adjustment of output power by changing the non-resonant compensation capacitor in primary side, with its highest efficiency reaching 95.8% and 94.5% respectively under the condition of with and without offset. © 2021, Society of Automotive Engineers of China.
