LM5160-Q1: LM5160-Q1: EMC issue (Conducted Emission)

Part Number: LM5160-Q1

Tool/software:

Hello,

We have flybuck topology as attached in the schematic. Output voltage ~15V and load at the secondary output approx, 200mA. (2.5W~3W max). 15V used for Gate switching of Inverter IGBT (16kHz switching)

we are getting huge conducted emission issue for 150KHz to 108MHz. pls suggest solution to filter it out. We have added CMC and MLCC but not useful so far. please suggest.
