    Based on a two-probe measurement approach, noise source and noise termination impedances of a switched-mode power supply (SMPS) under its normal operating condition are measured. With the known information of the noise source and noise termination impedances, an electromagnetic interference (EMI) filter can be designed systematically with good confidence. An example to design a power line EMI filter for a SMPS to meet a regulatory conducted EMI limit using the proposed procedure is demonstrated. © 2011 EMC Europe.

    An accurate measurement method to extract common mode (CM) and differential mode (DM) noise source impedances of a switched-mode power supply (SMPS) under operating condition is presented in this chapter. With a proper pre-measurement calibration process, the proposed method allows extraction of both the CM and the DM noise source impedances with very good accuracy. These noise source impedances come in handy to systematically design an electromagnetic interference filter for a SMPS with minimum hassle. © 2011 Bentham Science Publishers. All rights reserved.
