| Abstract |
Several measurements were performed on a power converter to obtain a model which allowed the
prediction of conducted EMI . The goal was to identify the relevant components and lay-out parameters
influencing the EMI generation and transmission. Some of the measured disturbances could not be
attributed to any real or parasitic component in the converter and finally, it was found that they came
from the measuring set-up (namely from the standard LISN and the measuring through the high pass
surge suppression filter, HPF). The introduction of real models for the measuring equipment in the
simulation, allowed a precise coincidence between simulated and measured EMI and showed that the
standard measuring equipment introduce some extra disturbances which are no present in the normal
working conditions. |
