【摘要】：在大功率无线电能传输系统的应用中,为降低系统设计难度会采用多接收耦合线圈并联的方式降低器件应力,但是对该模式的特性需要详细分析。在相同输出功率和负载的约束下,对比分析一对一耦合线圈模式和多接收耦合线圈模式,采用固定变量法分析多接收耦合线圈个数与系统互感、频率、负载和效率的关系。在多接收耦合线圈模式下,对单负载和多负载两种情况下系统参数进行推导和分析,论证多接收耦合线圈在提升系统效率方面的优势。最后,通过实验结果验证了多接收耦合线圈模式对系统效率提升有一定的作用。
[Abstract]:In the application of high-power radio energy transmission system, in order to reduce the system design difficulty, the multi-receiving coupling coils are used in parallel to reduce the device stress. But the characteristics of the mode need to be analyzed in detail. Under the constraints of the same output power and load, the one-to-one coupling coil mode and the multi-receiving coupling coil mode are compared. The fixed variable method is used to analyze the relationship between the number of multi-receiving coupling coils and the mutual inductance, frequency, load and efficiency of the system. The system parameters are deduced and analyzed in the case of single load and multi-load, and the advantages of multi-receiving coupling coil in improving system efficiency are demonstrated. Finally. The experimental results show that the multi-receiving coupling coil mode plays an important role in improving the efficiency of the system.
