摘要
磁感应耦合无线电能传输是无线电能传输方式的一种,该技术日趋成熟,已经被应用于许多行业,如电动汽车、电子产品、医疗设备、工业设备等行业。介绍了几种传统的无线电能传输方式的工作原理,并对比了这几种传输方式的优缺点。介绍了松耦合变压器的结构,并分析了不同补偿方式下,单补偿网络与双补偿网络拓扑的优缺点,进而确定试验中原、副边均采用串联补偿电容的拓扑结构。考虑变压器线圈内阻,计算谐振网络传输功率和效率与松耦合变压器互感值和系统工作频率之间的变化关系,再根据变化规律选择合适的工作频率和变压器互感值。对系统进行化简建模分析,搭建系统仿真模型,通过仿真验证了整个系统设计的可行性。
Magnetic inductively coupled wireless power transmission is one type of wireless power transmission technology. This technology has become increasingly mature and has been used in many industries, such as electric vehicles, electronic products, medical equipment, industrial equipment, etc. The principles of several traditional wireless power transmission methods are introduced and their advantages and disadvantages are compared. The structure of the loosely coupled transformer is introduced, and the advantages and disadvantages of single compensation network topology and double compensation network topology under different compensation modes are analyzed. Then the topology structure of using series compensation capacitors at both primary side and secondary side is used in the test. Considering the internal resistance of the transformer coil,the relationship between the transmission power & efficiency of the resonant network and the mutual inductance value of the loosely coupled transformer & the operating frequency of the system is calculated, and then the appropriate working frequency and transformer mutual inductance are selected according to the variation law. The system is simplified and modeled, the system simulation model is built, and the feasibility of the whole system design is verified by simulation.
