Abstract:

针对多辐射源医疗电子设备的辐射EMI噪声,提出了基于独立分量分析算法的分析方法。采用独立分量分析(IndependentComponentAnalysis,ICA)算法处理医疗电子设备中多辐射源叠加的近场辐射时域信号,得到多个独立的共模/差模辐射源,找出引起辐射噪声超标的源头,即可对该元器件实施针对性的整改措施。相较于目前的多辐射源分析方法,此方法能更准确快速地找出症结所在,较为容易操作和实现。采用双共模混合源、双差模混合源和共差模混合源3种模型进行实验,结果验证了该方法的可行性,最后将此方法应用于医疗电子设备,其结果成功验证了该方法的有效性,此项研究对今后的复杂电子设备溯源方法和多辐射源整改有积极参考意义。
