Nowadays, the Permanent Magnet Synchronous Motors (PMSM) are gaining popularity among electric motors due to their high efficiency, high-speed operation, ruggedness, and small size. PMSM comprise a trapezoidal electromotive force which is also called synchronous motors. Direct Torque Control (DTC) has been extensively applied in speed regulation systems its better dynamic behavior. The controll...

An improved segment reduction-based space vector pulse width modulation (SVPWM) for an F-type three-level inverter (FT2LI) is presented in this article. The proposed SVPWM algorithm decreases the additional switching state transition of each triangle with application nine- and three-segment reduction strategy. main feature technique that it eliminates second-order harmonics output side good tot...

The multilevel converters are extremely widespread alternatives within megawatt power level as well medium voltage applications due to their excellent execution than the typical two-level converters. widely applied control strategies aimed at inverters Sine Pulse Width Modulation (SPWM) and Space Vector (SVPWM) strategies. In between these two PWM methods, SVPWM strategy has compared SPWM a res...

<p>Electrical submersible pumps (ESPs) are multistage centrifugal driven by specially designed three-phase induction motors. They used in many applications such as nuclear and petroleum industries. In the presented paper, we study speed control of an ESP pump using a rule-based fuzzy logic controller (FLC). As case study, oil well is considered to analyze effects changing on both motor pa...

Any industrial or power sector application requires a pulse width modulation (PWM) inverter. Industrial drives in particular are highly concerned with standards. To satisfy the voltage source inverter (VSI) objects, variety of PWM approaches used, including DC input utilizations, suppression higher and lower order harmonics, as well spreading acoustic noise reduction, among others PWMs. One bet...

Currently, open-end winding induction motors fed by a dual inverter (OEWIM-DI) present an innovative approach to enhance the performance of modern electric drive systems, such as electrical vehicles and aircraft applications. However, DI topology requires proper switching control strategy enable OEWIM fully achieve its performance. This work aims investigate experimentally impact different deco...

Acknowledgment First of all, I would like to thank my parents who raise me and support me to do further study in Norway. I appreciate the help from my supervisor Lars Einar Norum and Phd student Hamed Nademi. I benefit a lot from their meticulous attitude to study, abundant knowledge and minded guidance. I am very grateful that NTNU Department of Electric Power Engineering provides very good ha...
