Application of Supercapacitor Energy Storage Devices

Abstract

The article discusses an actual theme about improving of energetic efficiency of industrial induction drives. New AC motor control schemes with supercapacitor energy storage devices for motor stator parametric control in continuous and pulse modes are developed. The starting device allows decreasing of motor torque jerks at the beginning of the transient process thus providing elimination of the consumed energy and drive system mechanical wear. There is given the storage system efficiency factor calculation in the capacitor charging mode with constant current. The new device has a higher efficiency factor
