    Tips: How to use filter to suppress EMI of switching power supply?
    Filter is an effective measure to restrain interference, especially conducting interference and radiation interference for switching power supply EMI signal. Conducting interference signal in any power line could be expressed by differential mode and common mode signal. Differential mode interference will transmit between 2 wires, belonging to symmetrical interference; common mode interference transmits between wire and grounding (housing), belonging to non-symmetrical interference. Under normal condition, differential mode interference has small range, low frequency, and the caused interference is small. Common mode interference has large range, high frequency, able to generate radiation through wire, and the caused interference is large. Therefore, if you want to weaken conducting interference and control the EMI signal under the limit level which is stipulated by related EMC standard, the best way is to install EMI filter in switching power supply input and output circuit. Working frequency of switching power is about 10kHz~100kHz. Most of EMC standards specified that the limit value of conducting interference level is from 10 kHz. Referring to high frequency band EMI signal generating by switch power supply, only choose the EMI filter with decoupling circuit or simple network structure, and then you can get satisfied effect.
