In this manuscript, the single stage boost inverter is proposed to eliminate common-mode voltage (CMV) and electromagnetic interference (EMI) in motor drives. The topology has capability of eliminating effects intrinsic CMV without any additional filters, active or passive elements, modified pulse width modulated (PWM) techniques. This with rearrangement filter components from ac side mid place...

although, single-sided linear induction motor (slim) utilization has increased in railway applications due to their numerous advantages in comparison to rotational induction motors (rim), there are some sophistication in their mathematical models and electrical drive. this paper focuses on the problems of slim modeling, with assuming end-effect on the basis of field oriented control (foc) as a ...

This paper deals with detection and diagnosis of Stator Inter turn fault of three phase Induction motor. The proposed method is based on the stator current Clarke vector pattern. Three phase stator currents are used to construct Clarke vector pattern in order to distinguish the “healthy” and “faulty” condition of induction motor. The covered area for each pattern is calculated and the per unit ...
