摘要
针对无线电能传输系统中耦合机构易偏移导致系统输出电流变化问题,研究具有抗偏移特性的双拓扑无线电能传输系统。首先分析SS与LCC-LCC拓扑电路的输出特性,选取DDQ线圈结构实现线圈间的解耦。然后提出基于粒子群参数优化算法对补偿网络的参数进行优化使其具有更好的抗偏移特性。最后在PSIM仿真软件中搭建系统电路验证理论分析的可行性。仿真结果表明,系统耦合机构的偏移范围为0~160mm,输出电流波动范围8.52~9.36A,输出电流波动比例为±4.7%,系统效率最高可达89.47%。
Aiming at the problem that the output current of the wireless power transfer system was changed due to the easy migration of coupling mechanism,a dual topology wireless power transfer system with anti-migration characteristics was studied.The output characteristics of SS and LCC-LCC topological circuits were analyzed firstly,and DDQ coil structure was selected to realize the decoupling between coils.Then,the parameters of compensation network were optimized based on particle swarm optimization algorithm to make it have better anti-migration characteristics.Finally,the system circuit was built in PSIM simulation software to verify the feasibility of theoretical analysis.The simulation results showed that the offset range of the system coupling mechanism was 0~160mm,the output current fluctuation range was 8.52~9.36A,the output current fluctuation ratio was±4.7%,and the system efficiency was up to 91.47%.
