Original question:
Part Number: TPSF12C1
Tool/software:
I hope Timothy Hegarty can help answer this question. This is about the simulation file provided by Timothy Hegarty in the previous discussion of Totem pole PFC with active EMI filter. I ran the simulation file provided at the end and it showed that there was a problem. Could you help confirm whether there is a problem with the simulation file?
2768.TPSF12C1EVM-FILTER with TTPL boost stage.sxsch
I would like to ask a stupid question here. Why is the compensation current injected only into N? In theory, when doing EMI testing, wouldn't the LISN be scanned once for each L or N? If the compensation current is injected only on one side (L or N), will the CM noise of only one side be reduced?
Hello user6055081
I was able to use the same file and run it in SIMPLIS. It is converging without any issues.
Could you please use the following file? https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/196/2768.TPSF12C1EVM_2D00_FILTER-with-TTPL-boost-stage_5F00_v2.sxsch
Also, could you please confirm what are the simulation settings that you are using? please use the following settings and rerun? -
Thanks and regards,
I checked my settings and they are the same as yours, but it still can't converge. However, I found a way, which is to set the cycles before launching POP higher (200). If anyone has this problem, you can try my method. Thank you.
