摘要： An entirely integrated EMI filter is based on a flexible multi-layer strip material. An EE or EI core comprises two side pillars and one middle pillar and forms a closed magnetic circuit. The middle pillar has an air gap. A first winding and a second winding respectively are wound around the two side pillars in a same winding direction. The middle pillar is wound with a third winding and a fourth winding, or with only a fifth winding. Passive components (e.g., all passive components) of the EMI filter are integrated into one core so that in its differential mode, insertion loss is significantly reduced, the size and volume are reduced, and the distribution constant of the EMI filter has less impact on the filter's performance.
摘要翻译：完全集成的EMI滤波器基于柔性多层条带材料。 EE或EI磁芯包括两个侧柱和一个中间柱，并形成闭合磁路。中柱有气隙。第一绕组和第二绕组分别以相同的卷绕方向缠绕在两个侧柱上。中间支柱用第三绕组和第四绕组缠绕，或仅用第五绕组缠绕。 EMI滤波器的被动元件（例如全部无源器件）集成到一个核心中，因此在差分模式下，插入损耗显着降低，尺寸和体积减小，EMI滤波器的分布常数影响较小过滤器的性能。
