Part Number: TMDXIDDK379D
I am looking at the schematics of TMDXIDDK379D board, in AC power filter module, which is M1, there is a common mode choke. What is the purpose of using this choke? Is it a transformer to increase the voltage level of the input DC? Also as I understanf, L1 and C2 are for filtering purposes, but I don't see any smoothing capacitor in the diagram. Could you please help me with these questions?
It is meant for emi filtering purposes, not to boost the input voltage. Basically, that bunch is for filtering the locally generated noise from getting into ac mains. DC filter cap is shown separately.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
