Hi all,
I am looking for a device that will differentiate the dominant component(either
common-mode or differential-mode current) in the total conducted noise emission
current of a product measuring through its' power cord using a LISN.
I called this device "common/differential mode current separator". In conducted
noise emission measurement, both common-mode and differential mode noise
current are measured by LISN and the LISN can't tell which mode is the dominant
current.
I came across a paper by Clayton Paul and Keith Hardin which explain the
usefulness of a separator like this that would identified the dominant current
from the total current. Hence, the correct capacitor value(either X-caps or
Y-caps) can be changed accordingly so to reduce the overall conducted noise.
The book by Clayton Paul "Introduction to Eletromagnetic Compatibility" has
also mention about this device.
I have contacted a few persons trying to look for the person who have actually
built this separator himself and I am also looking for any vendor who have this
product for sale. So far, my effort has yield no results.
Can anybody point me to the right person so that i can try to built this
separator myself. Any other suggestion and comments are greatly appreciated.
Best Wishes,
