Calculation of core losses of a six-phase induction motor with third harmonic current injection

Büyükbaş, Afşin
The advantages of using a six-phase induction motor for industrial drives, over the conventional three-phase drive can be summarized as improved reliability, reduction on the power ratings for the static converters and harmonic reduction. A technique of injecting third harmonic zero sequence current components in the phase currents to improve the machine torque density was presented recently by another research study. However, to meaninigfully evaluate the performnce of such machines and/or to be able to make good designs; it is necessary to obtain an accurate mathematical model for the loss calculation. The calculation of high frequency loss in this context presents a very difficult problem. In this thesis a modified version of a loss calculation model, which was developed in another MS thesis will be applied to a six-phase induction motor with third harmonic current injection.


Implementation of a vector controlled induction motor drive
Acar, Akın; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2004)
High dynamic performance, which is obtained from dc motors, became achievable from induction motors with the recent advances in power semiconductors, digital signal processors and development in control techniques. By using field oriented control, torque and flux of the induction motors can be controlled independently as in dc motors. The control performance of field oriented induction motor drive greatly depends on the correct stator flux estimation. In this thesis voltage model is used for the flux estima...

Çetin, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007)
In this thesis, design and implementation of a distribution-type, voltage source converter (VSC) based static synchronous compensator (D-STATCOM) having the simplest converter and coupling transformer topologies have been carried out. The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
Optimizing transient and filtering performance of a C-type 2nd harmonic power filter by the use of solid-state switches
Gerçek, Cem Özgür; Ertaş, Arif; Department of Electrical and Electronics Engineering (2007)
In this research work, the performance of a C-type, 2nd harmonic power filter is optimized by the use of a thyristor switched damping resistor. In the design of conventional C-type, 2nd harmonic filters; the resistance of permanently connected damping resistor is to be optimized for minimization of voltage stresses on filter elements arising from switchings in transient state and for maximization of filtering effectiveness in the steady-state. Transformer inrush current during energization of power transfor...
Prediction of torque and inductance displacement characteristics of asymmetrically slotted variable-reluctance motors using a simplified model for numerical field solution
Ertan, Hulusi Bülent (1999-09-01)
For prediction of static and dynamic performance of doubly-salient motors, it is essential to know their flux linkage-position-excitation characteristics and also the static torque characteristics. At the design stage determination of these characteristics presents difficulties because of highly nonlinear behavior of the magnetic circuit. It is possible to use numerical field solution of the complete motor to obtain this information. This, however, requires expertise on a professional program and may be exp...
