摘要

针对一次侧LCC、二次侧LC串联拓扑（LCC-S）的磁场耦合式无线电能传输系统（WPT）,建立其数学模型,同时考虑实际系统元器件应力约束以及元件参数漂移的影响建立多目标优化模型。从工作模式分布、元件应力、传输效率及输出功率等多个不同角度分析其多工作模式运行的优缺点,并基于多目标遗传算法对补偿网络参数进行优化配置,从而优化WPT系统各工作模式的传输性能。在此基础上对优化前后的各工作模式特性进行对比分析,最后通过实验验证多目标优化效果,实验结果表明,该优化方法改善了各工作模式的传输性能。

Abstract：

The mathematical model of magnetic field coupled wireless power transfer (Wireless Power Transfer, WPT) system is established based on the primary side with LCC compensation and the secondary side with LC series compensation(LCC-S). Meanwhile, considering the influence of actual system component stress constraints and component parameter drift, a multi-objective optimization model is established. The advantages and disadvantages of multi-operation modes are analyzed from different perspectives such as working mode distribution, component stress, transmission efficiency and output power. The compensation network parameters are optimally configured based on multi-objective optimization algorithm to improve the transmission performance of each operation mode. Then the transmission characteristics are analyzed longitudinally before and after optimal configuration. Finally, the multi-objective optimization is verified by experiments, and the transmission performance of each operation mode is improved.

Key words： Wireless power transfer LCC type compensation topology multi-operation modes optimal configuration
