Effect of defective NPC three level inverter on nonlinear command of induction motor

Speed Induction Motor (IM) control is an area of research that has been in evidence for some time now. In this paper, a nonlinear controller presented the induction motor drives. The designed based on input-output feedback linearization technique. decouples flux from speed and makes synthesis linear controllers possible. This article associated with NPC three level inverter defective, faults are usually caused by operating switch elements. Switching defects occur rectifier diodes, capacitor IGBT switches. switches defected reduce performance motor, our study. We applied to test their robustness detection fault influence physical parameters purpose, we two faults, started creating K1 K7 which first second arm inverter. Then created K1, K10 arms simulation results done use Matlab/Simulink show detection, effect different responses.
