滤波电路的基本概念：滤波电路是由电感、电容、电阻、铁氧体磁珠和共模线圈构成的频率选择性网络，低通滤波器是电磁兼容抑制技术中普遍应用的滤波器。为了减小电源和信号线缆对外辐射，接口电路和电源电路必须进行滤波设计。

交流端电源EMI滤波器

电源 EMI 滤波器是一种无源双向网络，它一端接电源，另一端接负载。在所关心的衰减频带的较高频段，可把电源 EMI 滤波器看作是“阻抗失配网络”。

网络分析结果表明，滤波器阻抗两侧端口阻抗失配越大，对电磁干扰能量的衰减就越是有效。由于电源线侧的共模阻抗一般比较低，所以滤波器电源侧的阻抗一般比较高。为了得到较好的滤波效果，对低阻抗的电源侧，应配高输入阻抗的滤波器；对高输入阻抗的负载侧，则应配低输出阻抗的滤波器。

普通的电源滤波器对于数十兆以下的干扰信号有较好的滤波作用,在较高频段,由于电容的电感效应,其滤波性能将会下降。对于频率较高的干扰情况，要使用馈通式滤波器。该滤波器由于其结构特点，具有良好的滤波特性，其有效频段可以扩展到 GHz，因此在无线产品中使用较多。

滤波器的使用，最重要的问题是接地问题。只有接地良好的滤波器才能发挥其滤波作用，否则是没有价值的。滤波器使用要注意以下问题：

（1）滤波器放置在电源的入口位置；

（2）馈通滤波器要放置在机箱（机柜）的金属壁上；

（3）滤波器直接与机柜紧密连接，滤波器下面不能涂保护漆；

（4）滤波器的输入输出引线不能并行，交叉。

直流电源端口处理

开关电源与系统内部晶体以及各时钟频率是主要的干扰源，通常采用磁珠、电容、电感等常规手段滤波，另外也可采用共模电感在电源端口进行共模滤波，防止系统干扰通过电源线发射出去。电源端的共模电感的使用需要注意：

（1）地层和电源层不能随便铺设；

（2）滤波电路的输入、输出之间一定要有良好的隔离，才能最大限度地发挥共模电感的滤波作用。

案例分享：

如下图为汽车仪表盘 24V 直流电源端口传导测试频谱图，高频段不满足 GB18655 LV3 的限值要求：

电源输入端口的原理图如下：

在该系统电路中，后端的开关电源与系统内部晶体以及各时钟频率是主要的干扰源头。L 是共模电感，可对该电源端口进行共模滤波，防止系统干扰通过电源线发射出去。电源输入端口的PCB图如下：

其中 L17 表示共模电感的位置。经过分析发现，共模电感下面的地层敷铜是多余的。此敷铜会起到被隔离的共模电感两侧容性耦合的作用，使共模电感的作用在一定程度上丧失。耦合产生的等效原理图如下：

C1 和 C2 表示多余敷铜引起的分布电容，它在一定的频率下将共模电感两端联通，所以来自后级的干扰通过分布电容直接流向传导骚扰的测试仪。为了验证分析的正确性，修改 PCB，将多余的地层取消，取消多余地层后的 PCB 图如下：

取消多余地层后传导骚扰得到很大的改善，传导测试结果如下：

端口滤波器

信号端口是比较容易出现共模干扰的问题，如果不注意很容易辐射超标。

1.接口处既有滤波又有防护电路，应该遵从先防护后滤波的原则。

防护电路用来进行外来过压和过流抑制，如果将防护电路放置在滤波电路之后，滤波电路会被过压和过流损坏。

2.滤波电路应靠近接口放置。避免已经经过了滤波的线路被再次耦合。

总结

解决EMC问题需要找到问题“源”，找到问题“源”需要一个找问题的方向，这就需要掌握强大的EMC的理论基础。本文中韬略科技详细解析了滤波设计思路，希望能对用户有所帮助。

信号端口滤波器将是信号线EMI解决方案最明智的选择

在EMI测试中，信号线对于电磁噪声来说是一个很好的耦合传播途径，无论是外部还是内部干扰都能通过信号线传导至其他设备，因此信号端口滤波的好坏是影响设备EMI是否超标的一个重要因素。在信号处理中，滤波器的使用是最常见的信号处理方式之一。韬略科技介绍的信号端口滤波器件将是明智的选择。
