High-voltage systems including electric vehicles, industrial robots, communications infrastructure equipment, and renewable-energy installations often require accurate current measurements. You can use a current-shunt or Hall-effect sensor to make such measurements, but recent innovations have given the Hall-effect current sensor an edge up over current shunts in many applications.
Consider the tradeoffs between the shunt and Hall-effect approaches to current measurement. Traditionally, shunt-based current measurement has provided better accuracy and lower drift over the entire operating-current range, over high and low temperature extremes, and throughout the useful life of the system in which it’s used.
