【摘要】 为了进一步提高LCC-S型无线电能传输(WPT)系统的抗偏移性能,设计了一种高抗偏移集成LCC-S型的WPT系统。首先,通过对集成LCC-S型电路进行分析,得出集成LCC-S型电路内3个耦合系数与电压增益的关系。其次,在Ansys Maxwell软件上对所选耦合机构进行仿真,初步证明了集成LCC-S型具有优越的抗偏移特性。最后,搭建了一台150 W的实验样机,实验结果证明了集成LCC-S型系统能够在偏移较大范围内实现恒压输出,证明了系统抗偏移特性的有效性。更多还原

【Abstract】 In order to further improve the anti offset performance of the LCC-S type wireless power transmission(WPT)system,a high anti offset integrated LCC-S type WPT system is designed.Firstly,by analyzing the integrated LCC-S type circuit,the relationship between the three coupling coefficients and voltage gain in the integrated LCC-S type circuit is obtained.Secondly,simulation is conducted on the selected coupling mechanism using Ansys Maxwell software,which preliminarily demonstrates that the integrated LCC-S type has superior anti offset characteristics.Finally,a 150 W experimental prototype is built,which proves that the integrated LCC-S type system can achieve constant voltage output within a large range of offset,demonstrating the effectiveness of the system’s anti offset characteristics.更多还原
