Efficiency Analysis and Parameter Optimization of CPT System

为了解决谐振耦合拓扑结构不同的非接触电能传输(CPT)系统效率计算方法不统一的问题,通过对4种基本谐振耦合拓扑结构的CPT系统的分析,给出了CPT系统效率计算的一般方法.在此基础上,为提高CPT系统的效率,通过对一种电流型CPT系统的建模,对系统谐振耦合拓扑结构的参数进行了优化设计,实现了该CPT系统高效率的能量输出.最后,以该电流型CPT系统为试验模型,对提出的效率计算方法和优化设计进行了试验验证.结果表明:该电流型CPT系统谐振耦合拓扑结构最大效率的试验结果为92%,而其优化理论值为93%.

In order to solve the problem that the efficiency computing methods for CPT systems with different resonant coupling topological structures are different,a general method for efficiency computing of CPT systems with different resonant coupling topological structures was proposed through analyzing CPT systems with four typical resonant coupling topological structures.To raise the efficiency of CPT systems,the parameters of the resonant coupling topological structure of a current-fed CPT system were optimized through mathematical modeling to achieve a high efficiency of energy output.In addition,by taking the current-fed CPT system as an experimental model,the effectiveness of the proposed computing method and the optimization of parameters were discussed.The result shows that the maximum efficiency of the resonant coupling topological structure of the current-fed CPT system is 92%,while its theoretical optimization value is 93%.
