该滤波器通常由无源元件组成，如电感器（扼流圈）和电容器，排列成LC（电感-电容）或Pi（C-L-C）网络配置。电感器通过呈现高阻抗来阻挡高频噪声，而电容器则将高频噪声分流至地（共模）或跨接在线路之间（差模）。这种组合形成了一个低通滤波器，允许所需的50/60 Hz交流电源以最小损耗通过，同时衰减更高频率的噪声分量。

An input filter conditions incoming AC power by reducing electromagnetic interference (EMI) and noise before it reaches the rectifier stage in AC-DC converters, ensuring stable operation and compliance with regulatory standards.
A standard bill of materials includes a common mode choke to suppress common-mode noise, X-capacitors for line-to-line filtering, and Y-capacitors for line-to-ground filtering, often combined with ferrite cores and additional capacitors.
By filtering out high-frequency noise and harmonics from the AC input, it protects downstream components, reduces electromagnetic interference, enhances power quality, and increases the overall efficiency and lifespan of the converter.
