摘要:
介绍了辐射骚扰机理和磁环抑制辐射骚扰原理,建立了磁环抑制辐射骚扰模型,运用毕奥—萨伐尔定律推导出磁环抑制电磁干扰的理论表达式,分析并使用MATLAB仿真了磁环形状、磁导率对抑制效果的影响. 结果表明,电磁干扰抑制效果随磁环长度的变化快于随外径的变化,抑制效果的变化趋势与磁导率成正相关. 使用3 m电半波暗室针对磁环形状、磁导率对抑制效果的影响作了实验分析,仿真结果与实验结果一致.
Abstract:
This paper introduces the mechanism of radiation disturbance and the principles of magnetic ring restraining radiation disturbance,establishes the model of magnetic ring restraining radiation disturbance,deduces the theoretical expression of magnetic ring restraining electromagnetic interference by using Biot-Savart law,and analyzes and simulates the influence of magnetic ring shape and magnetic permeability on restraining effect by MATLAB. The results show that the electromagnetic interference suppression effects changes faster with the magnetic ring length than with the outer diameter,and the change trend of the suppression effect is positively correlated with the magnetic permeability. The influences of magnetic ring shape and magnetic permeability on the suppression effect are experimentally analyzed by using 3m anechoic chamber. The simulation results are consistent with the experimental results.
