The Spatial Effect and Compensation ofCurrent Sensor Differential Gains for Three-Phase Three-Wire Systems

Current sensor errors affect torque control and saliency-tracking position estimation of AC machines. In this paper, a spatial model of current sensor gain deviation is developed and used to determine its effect on general current measurement, verified with experimental data. Three current sensors e...
