摘要
引信装定接收电路作为装定系统负载,其阻抗角特征对磁共振耦合无线装定系统的能量传输性能具有重要影响,针对该问题,首先基于互感耦合理论,分析了负载阻抗通过阻抗映射对中继线圈等效参数的影响,然后仿真结合实验研究了能量传输性能、收发端耦合磁场空间分布特征随负载阻抗角的变化规律。仿真实验结果表明,系统传输性能随负载阻抗角绝对值的增大而下降,对于负载阻抗中电阻部分相同的装定系统,若负载阻抗角相同,则不论电抗部分构成如何,其传输性能也相同,收发端线圈耦合磁场空间分布特征随负载阻抗角的变化规律与能量传输性能变化规律相对应。
As the load of setting system,fuze receiving circuit impedance angle characteristic has an important influence on the power transmission performance of the wireless setting system based on magnetic resonance coupling.Based on the theory of mutual inductance coupling,the influence of the load impedance on the equivalent parameters of the repeating coil by impedance mapping was analyzed.Then,the power transmission performance and distribution characteristics of the coupled magnetic field with different load impedance angles were studied by simulation and experiment.The simulation and experiment results showed that transmission performance of the system decreases as the absolute value of the load impedance angle increases.For the setting systems with same resistance part of the load impedance,if the load impedance angle was same,the transmission performance would be same regardless of the configuration of the reactance part.The spatial distribution of the coupling magnetic field in the sending and receiving coils changed with different load impedance angle,and it was consistent with the changing rule of power transmission performance.
