Abstract

This paper presents dual scalar controlled drives of induction motors using single voltage source inverter through long feeding cables. As known, when the cable length is long, over-voltages at motor terminal could be doubled from the pulsed output voltage at inverter terminal. In this paper, a half DC-link inverter is implemented to drive two motors simultaneously for different configurations of cable lengths. The implemented inverter drastically reduces the over-voltage at both motor terminals with a proper duration time of V dc/2 level (β). Simulation and experimental results are provided to show the effectiveness of over-voltage reduction by using this inverter. According to these results, for two motors with different cable lengths, this β should be calculated based on the cable length closed to the longer one. ©2008 IEEE.
