Abstract :
The advent of pulsewidth modulation (PWM) drives utilizing insulated gate bipolar transistor (IGBT) technology has made the selection of the interconnecting power cable between the drive and load an important decision. Motor bearing currents, reflected voltage wave, and electromagnetic interference shielding have become areas of concern in the PWM drive system. Based on the previous literature, a cable with a high conductivity and continuously welded and corrugated aluminum sheath is most advantageous. This paper emphasizes the worthiness of this type of armored cable
