I'm trying to design an EMI filter for a 3-phase induction motor driver. I've looked at some example filter designs but in one of them I couldn't understand the capacitors and resistors what they are stands for?
There are 4 X-Y caps at the beginning and at the end, 1 common mode choke and DC bulk capacitors. Can you explain why the series resistors and other capacitors are used? I circled them in the picture.
