摘　　要：采用全桥逆变电路的无线电能传输(wirelesspowertransfer,WPT)系统存在直通问题,采用单管逆变电路的WPT功率有限。该文提出一种基于单管多重并联结构的恒流恒压WPT方案,并搭建实验平台验证其有效性。首先,使用S-LCL/S补偿网络实现恒流恒压输出,并通过Saber仿真系统搭建了单管多重并联恒流恒压无线充电系统模型;然后,使用Maxwell有限元法对磁耦合器进行仿真设计,并借助仿真结果搭建实验平台,验证方案的正确性。该实验平台包括多种硬件和软件,可以加深学生对电力电子知识的理解,提高学生的科研实践能力。The wireless power transfer(WPT)system with full-bridge inverter circuit has shoot-through problem,and the WPT power with single-switch inverter circuit is limited.In this paper,a constant current and constant voltage WPT scheme based on single-tube multi-parallel structure is proposed,and an experimental platform is built to verify its effectiveness.Firstly,the S-LCL/S compensation network is used to realize the constant current and constant voltage output,and the single-switch multi-parallel constant current and constant voltage wireless charging system model is built by Saber simulation system.Then,the Maxwell finite element method is used to simulate the magnetic coupler,and the experimental platform is built with the help of the simulation results to verify the correctness of the scheme.The experimental platform includes a variety of hardware and software,which can deepen students'understanding of power electronics knowledge and improve students'scientific research and practice ability.
