Optimization of Design Method of T-Type Impedance Matching Network for Wireless Charging System Based on Rectified Load Compensation
摘要
Abstract
The impedance matching of the wireless charging system is of great importance for improving the power transmission capability of the system. To avoid the shortcomings of the existing resistive rectified load analyzing method, an optimization method of T-type impedance matching network for wireless charging system was proposed based on rectified load compensation. Firstly, the T-type impedance matching networks were analyzed based on traditional rectified load analyzing method. Secondly, the non-linear characteristics of the rectified load were analyzed, and a conclusion was obtained accordingly that the inductive characteristics of the rectified load could not be neglected. According to the conclusion above, the method of compensating the rectified load was studied, and theT-type impedance matching network was optimized. Finally, simulations and experiments were conducted to verify the proposed optimization method. The results show that the proposed optimization method can improve the power transfer efficiency of the wireless charging system by nearly 1% and the output power from 2.52kW to 2.77kW.关键词
