罗姆（ROHM）针对使用电感降低开关噪声对策进行了总结。

1、使用电感的降噪对策

· 仅用电容无法充分消除噪声时，可考虑使用电感。

· 降噪对策中使用的电感大致有两种。

（1）绕组型电感：组成滤波器

（2）铁氧体磁珠：将噪声转换为热。

2、电感和铁氧体磁珠的阻抗特性

· 虽然铁氧体磁珠被归类为电感，但其频率－阻抗特性与普通电感不同。

· 铁氧体磁珠与普通电感相比，具有电阻分量R较大、Q值较低的特性，因此可利用该特性消除噪声。

· 普通的电感可容许较大的直流叠加电流，只要在其范围内，阻抗不怎么受直流电流的影响。

· 请注意，铁氧体磁珠对于直流电流容易饱和，饱和会导致电感值下降，谐振点向高频段转移，滤波特性产生变化。

3、使用绕组型电感的降噪对策：组成滤波器

· 普通电感构成的滤波器，可选电感值的范围较宽。

· 使用电感的Π型滤波器，在低频段，因电感和电容而发挥低通滤波器的作用。

· 到了高频段，由于电感会表现为电容、电容会表现为电感，从而π型滤波器起到高通滤波器的作用，因此无法获得噪声消除效果。

4、使用铁氧体磁珠的降噪对策：将噪声转换为热

· 铁氧体磁珠的Q值较低，因此在较宽频率范围内具有有效的降噪效果。

· 铁氧体磁珠在低频段基本上发挥低通滤波器的作用，在这个频段，对于直流电流容易饱和，因此使用这种电感值下降的铁氧体磁珠很难消除目标频段的噪声。

· 当电抗下降且越过与电阻分量的交叉点时，铁氧体磁珠发挥电阻的作用，可将噪声转换为热。

· 使用了铁氧体磁珠的滤波器，不仅可将噪声旁路消除，还可将噪声转换为热，因此有望实现优异的噪声消除性能。

· 发挥电阻功能且将噪声转换为热，是与使用绕组型电感的滤波器之间的巨大差异。

· 在更高频段，则与绕组型电感相同，发挥高通滤波器的作用。

5、共模滤波器

· 从严格意义上讲，共模滤波器并不是电感器，但在降噪对策中它是重要的磁性器件。

· 共模滤波器的结构是两个绕组绕在一个磁芯上，相当于两个电感组合。

· 共模滤波器是利用自感作用来阻止共模电流通过（斩波），从而消除共模噪声。

· 共模电流不流通、差模电流流通。

6、使用共模滤波器的降噪对策

· 作为开关电源的输入滤波器使用时，要使用差模阻抗较大的分裂绕组结构的共模滤波器。

· 这种滤波器一般作为电源线用共模滤波器销售。

· 虽然其差模噪声消除效果也值得期待，但是由于几百k～几MHz左右的差模阻抗非常低，因此一般与π型滤波器等差模噪声用的滤波器并用。

7、串扰相关的注意事项

· 有些PCB板布线布局，会因串扰而导致滤波效果下降。

· 串扰是因电路板布线间的杂散电容和互感，噪声与相邻的其他电路板布线耦合。

· 滤波器后的布线与含有滤波器前的噪声的布线相邻时，噪声因串扰而耦合，滤波效果下降。

· 作为对策，采用不与含有噪声的线路相邻的布局，可将噪声耦合控制在最低限度内。

8、GND线反弹噪声相关的注意事项

· 在使用了Π型滤波器的电感前后所配置的电容，其GND的设置方法可能会带来地线反弹噪声。

· 作为对策，为了避免噪声直接传播，可利用Via的寄生电感的手法，经由过孔（Via）与GND平面连接，改善效果较好。

如何用示波器来分离共模和差模噪声分量？

有效的输入滤波器设计对于满足开关模式电源传导发射的EMI标准至关重要。通常，EMI滤波器由共模滤波器和差模滤波器组成，这两个元件都必须进行设计和优化。有关共模噪声和差模噪声贡献的准确信息极大地有助于设计和优化EMI输入滤波器的任务。使用双输出LISN（或两个相同的LISN）以及示波器上的一些数学运算，可以直接在示波器上分离共模和差模噪声。

输出LC滤波器必不可少吗?

根据应用情况，也可以换成铁氧体磁珠和陶瓷电容器之类简单的滤波器。例如，小屏幕液晶电视机和 iPod Dock型的有源扬声器等扬声器电缆短的产品。若像大屏幕液晶电视机一样扬声器电缆长，辐射方面难以解决。
