| Summary: | A novel measurement method is proposed to
evaluate the performance of a ferrite core on a power cord under
actual operating condition. The proposed method allows the
common-mode impedance of a ferrite core under in-circuit
condition to be measured so that it provides a more realistic
assessment of the noise suppression capability of the ferrite core.
With a pre-measurement characterization process, possible error
due to parasitic effects of the measurement setup can be
determined and eliminated. Hence, good accuracy is achieved for
the proposed measurement method. |
