摘要
利用电路理论,对具有双负载接收线圈的磁谐振耦合式无线充电系统进行了建模分析,导出了系统的传输功率和效率表达式。通过数值分析的方法,针对交叉耦合效应对系统传输功率、效率的影响进行了细致的研究,并提出了一种在回路中附加电抗来补偿交叉耦合效应的方法。通过仿真和实验验证了这种方法的可行性。
Based on circuit theory, by analyzing and modeling of magnetically coupled resonant wireless charging system with dual-load receiving coils, the expressions of transmission power and efficiency of the system are deduced. Using the method of nu- merical analysis, the influence of cross coupling effect on the transmission power and efficiency of the system was worth studying. Then a method of adding reactance to compensate for the cross coupling effect in the circuit is proposed and the simulation and ex- perimental results have proved its feasibility.
