摘　　要：以提高磁耦合谐振式无线电能传输(MCR-WPT)系统传输效率为主要目标,同时保证系统不发生频率分裂,对系统多个参数进行优化。利用互感模型分析影响MCR-WPT系统传输效率的因素,确定优化参数。从系统输入阻抗的角度分析系统产生频率分裂现象的原因及抑制方法。利用粒子群优化(PSO)算法对影响系统传输效率的因素进行优化,在抑制系统发生频率分裂的同时使系统传输效率达到最大,得到最优解对应的参数值。通过实验证明该方法有效提高了 MCR-WPT系统传输效率,对MCR-WPT系统的参数确定具有一定参考意义。The transmission efficiency of the magnetically-coupled resonant wireless power transfer(MCR-WPT) system is improved,while ensuring that the system does not undergo frequency splitting,multiple parameters of the system are optimized.The mutual inductance model is used to analyze the factors affecting the transmission efficiency of the MCR-WPT system and determine the parameters that need to be optimized.The causes and suppression methods of frequency splitting in the system are analyzed from the perspective of system input impedance.The adaptive particle swarm optimization(PSO) algorithm is used to optimize the factors affecting the transmission efficiency of the system,which can maximize the transmission efficiency of the system while suppressing the frequency splitting of the system,and obtain the parameter values corresponding to the optimal solution.Experiments have proved that this method effectively improves the transmission efficiency of the MCR-WPT system,and has certain reference significance for determining the parameters of the MCR-WPT system.
