Abstract. A method of direct measurement of the derivative of current necessary to determine the induct-ances in electric motors for reliable and efficient operation of sensorless control in AC electric drives is considered. The method is based on measuring the voltage drop across a calibrated inductance installed directly in the converter power circuit. To improve the method accuracy and reduce the effects of transi-ents and interference, a delta-sigma modulator is used to measure the voltage drop. Experimental re-sults obtained for three different inductive measuring shunts are presented.
Keywords: derivative of current, electric drive, sensorless control, delta-sigma modulator, inductive shunt
