Hi,
I need some help from somebody who has experience in motor control.
It is about current sensing with a sense resistor. I know it is easier to sense the current in the low side that in high side, but high side is better because it allows to detect short to ground.
There is something else that I don t understand (need sbdy to explain me) : if the sense resistor is on the low side it disturbs the ground, which for instance is not allowed in automotive.??
There is something else I want to ask, for 3 phase motor whqt do you think qbout sensing the current in the phase (i don t speak about how to do it, but about the application of sensing the current in the phase of the motor (BLDC,AC).
Many thanks, if somebody can recommand me a book that will be nice, I found nothing up to now, so the only solution I have is to speak with people who have experience.
