Hi Folks, I am working on a 3 phase motor controller, one each phase leg of the motor I have current sensors, they are transformer coupled and nominally float at 2.5 volts, they then swing between 0 volts and a maximum of 5 volts as they detect the alternating current flowing through. The scaling is something like 85amps for 1 volts. What I'm trying to do is get the total current value. From what I understand I should add all three current values together in my microcontroller, this should equal the total current. Of course I'll have to do some stuff on my microcontroller to do this, first of all subtract the 2.5 volt offset from each sensor, then remove any negative signs, then multiply the voltage by the 85 scalar and then add them all together. Does this make sense?
