摘要:
      感应耦合电能传输(Inductively Coupled Power Transfer, ICPT)系统接收端LCL谐振结构参数约束条件较多。传统设计方法需要进行反复迭代,较为繁琐复杂。针对该问题,提出了一种非线性规划求解临界导通模式单位功率因数LCL谐振结构参数的方法。将复杂繁琐的谐振结构参数设计问题转变为一般的非线性规划问题。该方法可以使得谐振结构参数在满足众多约束的前提下,充分的利用谐振结构各个元件,使得各个元件工作在较为接近的负荷水平,均衡的将谐振结构电压、电流应力分配到各个元件。最后,本文对所提方法进行了算例与实验验证,搭建了额定输出功率为2.1 kW的样机。通过实验验证了本文方法的可行性与正确性。
Abstract:
      The LCL resonant structure of the ICPT system receiver has many parameter constraints. The traditional design method needs repeated iteration, which is complicated. To solve this problem, a nonlinear programming method for solving parameters of the critical conduction mode unity power factor LCL resonant converter is proposed. The complicated resonant structure parameters design problem is transformed into a general nonlinear programming problem. This method can make full use of all the components of the resonant structure under the condition of satisfying the constraints, so that each component is worked at a relatively close load level. The voltage and current stress of the resonant structure is distributed to each component in a balanced way. Finally, an example is given to verify the proposed method, and a prototype with a rated output power of 2.1 kW is built. The feasibility and correctness of the method are verified by experiments.
