V. Srinath, Man Mohan, D. K. Chaturvedi . A Multilevel Inverter System for an Induction Motor with Open-Ended Windings. International Journal of Computer Applications. 163, 10 ( Apr 2017), 6-13. DOI=10.5120/ijca2017913528
The objective of this paper is to present a multilevel inverter topology for induction motor with open-end winding. Multi level inversion is achieved by feeding an open-end winding induction motor with a two-level inverter in cascade with three auxiliary circuits from one end and a single two-level inverter from the other end of the motor. The combined inverter and auxiliary system with open-end winding induction motor produces voltage space-vector location identical to five-level inverter. The proposed inverter drive scheme was simulated for different type of loads and also with sudden changes in the load. It is also capable of producing a multilevel pulse width modulation (PWM) waveform to a five level depending on the modulation range. The proposed topology has been simulated using MATLAB/SIMULINK with satisfactory results.
