基于LCC拓扑的ICPT系统混合补偿方法及验证
|
摘要
针对感应耦合电能传输(ICPT)系统的四种基本补偿结构在负载固定时无法调节系统传输功率的缺点,提出基于LCC拓扑的混合补偿方法,包括LCC/S与LCC/P两种补偿结构。利用高阶LCC结构与一阶串/并联结构的联合应用,不仅能够调节ICPT系统的传输功率,其相比于双LCC结构又能减小无功器件的使用,减小系统的复杂度。首先给出了基于互感模型的LCC/S与LCC/P的结构原理图,推导出两种结构的负载特性、功率特性等多个系统特征,并使用有限元仿真软件Comsol对两种补偿结构的软开关可行性、传输功率及传输效率进行了对比分析,证明了提出理论的可行性。最后,对运行频率发生偏移时的输出功率特性进行了仿真分析,为ICPT系统的补偿设计提供了思路。
In this paper,two compensation structures of LCC/S and LCC/P are proposed for the four basic compensation structures of inductive wireless power transmission (ICPT) system which cannot adjust the system transmission power when the load is fixed. The combination of high-order LCC structure and first-order series/parallel structure can not only regulate the transmission power of ICPT system,but also reduce the use of reactive power device and reduce the complexity of the system compared with double LCC structure. In this paper,the structural principle diagrams of LCC/S and LCC/P based on the mutual inductance model are given firstly,and the system characteristics such as load characteristic and power characteristic of the two structures are deduced. The feasibility of soft-switching,transmission power and transmission efficiency was compared and analyzed by using finite element simulation software comsol,which proves the feasibility of the proposed theory. Finally,this paper simulates the output power characteristics when the operating frequency is offset,which provides the idea for the compensation design of ICPT system.
