الملخص: | The feasibility of adding a common-mode (CM) choke
in the analog front end (AFE) circuit of a power line communication
(PLC) modem to reduce theCMnoise coupling onto the power
line is investigated. Based on a two-current-probe measurement
approach, theCMand the differential-mode (DM) equivalent electrical
models of a PLC modem are first developed. Both the CM
and the DM attenuations due to the addition of a CM choke when
the PLC modem is connected onto the power line network are then
determined. Besides the CM noise attenuation, the impact of the
CM choke on the PLC signal, which isDMin nature, is also studied. |
