多单元耦合的能量双向无线馈动系统分析及控制策略

Analysis of Multi-unit Coupling Bi-directional Wireless Power Transfer System and Its Control Scheme

  • 摘要: 双向无线电能传输技术是无线电能传输领域的一个重要研究方向。文中研究了含有(k+1)个能量传输单元的双向无线电能传输系统,通过建立(k+1)个传输单元的能量馈动模型,提出一种灵活控制系统功率流动方向以及有功出力(或功率分配)的方法。该方法利用各回路单元双向变换器出口电压幅值以及相角之间的关系,降低了系统能流方向和功率分配的控制难度。以3回路能量传输单元的双向无线电能传输系统为例,给出了功率流动方向控制和有功出力控制的约束关系,并进行仿真与实验研究,结果验证了理论分析的正确性与可行性。

     

    Abstract: Bi-directional wireless power transfer technology is one of the important research branches of wireless power transfer.The bi-directional wireless power transfer system with k+1loop units is studied and its mathematic model is established.Moreover,the control scheme for both power flow direction regulation and power allocation via the relationships among converter voltages’amplitude and their phase difference is proposed.Then,the theoretical analysis and simulation are carried out for bi-directional wireless power transfer with three loop units and the constrain conditions of power flow direction and power allocation are also presented.Finally,the viability and feasibility of theoretical analysis are verified by simulation and experiments.
