Other Parts Discussed in Thread: PMP9171
Hi Team,
There is no explanation about how to choose L1, L2, R1, and R2 parameter for effective EMI reduction as input AC line filter in the datasheet
(I can understand that those components are used for AC line filtering for EMI reduction from following description in the UCC28910's datasheet )
10.2.1.2.2 Input Stage Design and Bulk Capacitance
4. A line filter (L1, L2, R1, and R2) to reduce EMI generated by switching.
Could you tell me how to choose those parameters properly?
Do you have any app note about the input line filter setting? If yes, please let me know the document number.
I'm also curious what kind of side effects will come out if we don't put the line filter in there since those components are big size and take non-negligible costs.
Could you tell me what kind of case we can remove the filter in the system using UCC28910?(ex, PMP9171)
Regards,
