摘　　要：恒压CV(constant-voltage)输出双边LCC补偿感应电能传输IPT(inductive power transfer)系统存在轻载效率低的问题,为了优化CV输出双边LCC补偿IPT系统轻载效率,基于求解近似最优解思想,提出1种双边LCC补偿拓扑的参数设计方法。分析了CV输出时零相位角ZPA(zero phase angle)条件及松耦合线圈损耗,通过搭建6.6 kW的实验原理样机进行实验验证。实验结果表明,所提补偿参数设计方法可以提高系统效率,尤其是轻载效率,6.6 kW满载效率为95%,1.32 kW轻载效率可达93%。The double-sided LCC compensated inductive power transfer(IPT)system with constant-voltage(CV)output suffers from the problem of low efficiency under light load.To solve this problem,based on the idea of approximate optimal solution,a parameter design method for double-sided LCC compensation topology was proposed.The zero phase angle condition in CV output mode and the loss of a loosely coupled coil were analyzed,and a 6.6 kW prototype was built to verify the proposed method.Experimental results show that the system efficiency can be improved with the proposed compensation parameter design method,especially in the case of light load.The system efficiency can reach 95%under full load of 6.6 kW and 93%under light load of 1.32 kW.
