A Multilevel Inverter System for an Induction Motor with Open-Ended Windings
نویسندگان
چکیده
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.

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
