Fast switching in SMPS generates a large amount of Electromagnetic Interference (EMI). The EMI consists of mainly common mode and differential mode noises. In the present work, conducted EMI is studied and a procedure for designing an AC power line filter is proposed. As an application of this design procedure, conducted EMI noise measurement and filter design of a boost AC-DC converter with PFC has been achieved while successfully satisfying the CISPR22/EN55022 limit in the frequency range from 150KHz to 30MHz, which confirms the validity of the design procedure.
