Hello i am working on 3 Phase ACIM drive. now i have to work on current sense so that motor could not get damage under overload and short circuit condition.
my question is which is best method for current sense.
1) Hall effect sensor for AC current measurement at output phase
3) CT current sense at output phase
2) Low side current sense of all 6 IGBT
please suggest me which method gives better measurement and cost effective
