IGBT Temp. & current sensor offset
#1
We are attempting to establish a relationship between IGBT temperature & phase current sensor offset on Geo direct PWM amplifiers/drives. Thus far, data we have collected does not suggest much of a correlation between IGBT temperature and the current sensor offset.

While one would typically expect sensor offset to be a partial function of temperature, we are not sure about phase current sensor to IGBT proximity on the Geo direct PCB. If anyone is familiar with board layout, such information would be most helpful.

Thanks.
