简介: The power filter is a low-pass filter circuit composed of inductor and capacitor, which allows DC or 50Hz current to pass through, and has a greater attenuation to the interference signal with higher frequency. Because the interference signal has the difference mode and the common mode two kinds, therefore the power supply filter must have the attenuation effect to these two kinds of interference.
