摘要
由于双LCL型无线电能传输(WPT)系统具有恒流输出特性以及较好的鲁棒性,故其已经在无线电能传输领域得到了广泛的应用。但是,在系统轻载时,逆变器输出电流存在畸变,此为双LCL型无线电能传输系统的固有缺点。针对此问题,在不影响系统原特性的基础上,提出了一种改进方法,并从理论上分析了改进方法的工作原理以及可取得的良好效果。最后,通过仿真分析和实验验证证明了理论分析的正确性。
Because of the double LCL wireless power transmission（ WPT） system has the characteristics of constant output current and better robustness, it has been widely used in the field of WPT system. However, when the system is light loaded, the output current of the inverter is distorted, which is the inherent shortcoming of the double LCL WPT system. To solve this problem, an improved method is proposed on the basis of not affecting the original characteristics of the double LCL WPT system. The working principle of the improved method and the good results can be obtained theoretically. Finally, simulation analysis and experimental verification prove the correctness of the theoretical analysis.
