摘要磁耦合感应式无线电能传输(MCI-WPT)感应区域传输效率高, 而磁耦合谐振式无线电能传输(MCR-WPT)谐振区域传输效率高, 为解决两者优势不可兼得的问题, 提出磁耦合双模无线电能传输(MCB-WPT), 引入转换开关组, 实现磁耦合无线电能传输系统拓扑结构可控, 使其可工作在MCI-WPT和MCR-WPT双模式下, 在一定范围内, 实现最佳能量传输。建模分析MCI-WPT与MCR-WPT传输效率与传输距离的关系;提出MCB-WPT方案, 建立其传输效率模型, 并给出MCB-WPT系统设计方法和控制策略。实验证明, MCB-WPT在感应区域和谐振区域均可获得较高传输效率。

Abstract：To combine the respective transmission efficiency advantages of the magnetically-coupled inductive wireless power transfer (MCI-WPT) in the inductive field and the magnetically-coupled resonant wireless power transfer (MCR-WPT) in the resonant field, the magnetically-coupled bi-module wireless power transfer(MCB-WPT) is presented in this paper, whose topology is changed according to the control by the state-switches.The MCB-WPT can work in the MCI-WPT mode and MCR-WPT mode with optimal transmission efficiency in the valid range.Moreover, the influence of the transmission distance on the transmission efficiency with MCI-WPT and MCR-WPT models is analyzed and the concept of MCB-WPT is proposed.Furthermore, the optimal design and control strategy is presented.The experiment shows that the high transmission efficiency can be obtained in both inductive field and resonant field with MCB-WPT.
