Other Parts Discussed in Thread: UCC28881
Dear ladies and gentlemen,
I am very interested in the UCC28881 and wanted to use it in a design for energy metering.
To work correctly, the analog ground has to have the same potential as the neutral conductor, because the AFE only has an input range of +/-600mV. With the second rectifier diode of the half wave rectifier (D3), this would not be possible to achieve. But it is stated that the diode is needed for better (common-mode conducted) EMI.
Do you know how the conducted emission test would perform without the second diode? Do I need something in addition, e.g. a common-mode choke?
Thank you very much in advance!
Best regards,
W. Fried
