Tool/software:
hello.
I am writing to ask a question about current sensing.
As shown in the current photo, I increased the input dc voltage to 500v.
I can see that the B-phase current and C-phase current are detected normally. However, it was confirmed that the A-phase current had severe ripples.(The photo on the left is the A-phase current, and the photo on the right is the B-phase current.)
It was confirmed that the current code uses the SDFM method, and as a result of measuring the SDFM output signals of phase A and phase B on the hardware, it was confirmed that there was no significant difference.(ex :SD_Data_IG_A)
Why is phase A sensing not working?
Thank you.
