In-circuit characterization of common-mode chokes

| Summary: | The two current probes measurement method was employed by other researchers to measure the radio-frequency impedance of ac power
mains. In this paper, with a modified measurement setup, the method is extended
to measure the common-mode (CM) impedance of a CM choke under in-circuit condition.With a premeasurement characterization process,
the effect of the measurement setup can be determined and eliminated.
The proposed measurement provides a more realistic assessment of the CM impedance characteristic of any CM choke under actual operating condition. |
