ABSTRACT:
An apparatus and method for measuring electric current. The apparatus includes a conductive shunt for developing a voltage drop in response to current flow through the shunt, a temperature sensor for sensing the temperature of the shunt, and an amplifier for amplifying the voltage drop across the shunt. The voltage drop developed by the shunt has a known dependence upon the temperature of the shunt. The amplifier has an output for producing a current signal indicative of current flow through the shunt and has a gain dependent upon the temperature of the shunt, to compensate the current signal for changes in the voltage drop across the shunt due to the known dependence upon temperature of the voltage drop developed by the shunt.
