摘　　要：在差、共模电感集成EM I滤波器的基础上,分析了差、共模电感集成的原理,实现了差、共模电感的平面磁集成,进行了电磁场有限元分析验证,并通过Matlab仿真软件对滤波电路进行了仿真。结果表明平面磁集成的EM I滤波器不仅体积小、高度低,而且有较好的滤波效果。Based on different mode and common mode inductarrce integrated EMI filters, analyzes the principle of different mode and common mode inductance integration to achieve planar magnetic integration of different mode and common mode, carries out finite element analysis and testing, and simulates filter circuit by Matlab simulation software. The result shows that the planar magnetic integrated EMI filter has not only a small size, low profile, but also a better effect of filtering.
