Three-phase Induction Motor (IM) drives are widely used in industrial equipments. One of the essential problems of 3-phase IM drives is their high speed and torque pulsation in the fault conditions. This paper shows Direct Torque Control (DTC) strategy for vector control of a 3-phase IM under opencircuit fault. The objective is to implement a solution for vector control of 3-phase IM drives whi...

to meet increasing demand for higher reliability in power electronics converters applicable in electric vehicles, fault detection (FD) is an important part of the control algorithm. In this paper, a model based open transistor fault diagnosis method is presented for a voltage-source inverter (VSI) supplying a five-phase PM motor drive. To realize this goal, a model based observer is designed to...

The performance of an Indirect Rotor Field-Oriented Control (IRFOC) scheme for Induction Motors (IMs) is strongly dependent on the motor parameters especially, rotor resistance. As such, to ensure high performance drive system, the variation of the rotor resistance due to the temperature increase need to be estimated based on the available terminal variables. However, the algorithm used to esti...

Nowadays, inverters are power electronics devices used in the renewable energy conversion systems and also to fed induction motors, therefore the continuity of service of power converter has been a major concern. This paper presents a new approach of open circuit fault detection in a pulse width modulation three phase voltage source inverter. The fault occurrence detection was based on the stan...

The multiphase induction motor is considered to be the promising alternative conventional three-phase motor, especially in safety-critical applications because of its inherent fault-tolerant feature. Therefore, attention many researchers has been paid develop different techniques for detecting various fault types motors, securely switch control mode drive system post-fault operation mode. sever...
