I have been reading all the documentations regarding this micro-controller and its front end 24bits ADC.
There is a single or three Fase meter app that describe using a current sense transformer or coil. directly connected to the in+ and -.
Ok but how the converter deals with the negative input? maybe i am a little new to current or energy metering.
But at the transformer it has to be a negative voltage right?
For Voltage measure that is ok they shift the voltage input to vref/2 and its ok to read.
I would really appreciate some help. just understanding how it works.
thanks in advance.
