Switched Reluctance Motors (SRM) have inherent advantages such as simple structure with non winding construction in rotor side, fail safe because of its characteristic which has a high tolerances, robustness, low cost with no permanent magnet in the structure, and possible operation in high temperatures or in intense temperature variations. The torque production in switched reluctance motor com...

Switched reluctance motor drive system has greatly practical value in electric vehicle applications. For the characteristics of switched reluctance motor and electric vehicle application requirements, how to reduce the torque ripple effectively and ensure its average output torque, all these become a hot spot of research. Based on this, first of all, the nonlinear model of switched reluctance m...

This paper presents an improvement to the fault ride-through (FRT) capabilities for a wind turbine that employs switched reluctance generator (SRG) using dynamic voltage restorer (DVR). The may be disconnected from grid by sag, swell, and faulty line in grid. To improve stator of SRG during failures, DVR is applied inject at point common coupling (PCC) into voltage. A control strategy based on ...

Accord to the theory of micro-step control, this study is about a design of a four-phase switched reluctance motor based on DSP-driven control system. Firstly, the study is about the design of the hardware circuit, such as the power inverter and its drive, current detection, position detection and the system power supply. And then to build a switched reluctance motor control system, TMS320L2812...

The switched reluctance motors had gained more attention among the variable speed drives due to its inherent simplicity and low cost. It is an electronically commutated motor and need to be driven from a converter. The excitation of the different phases of the converter is dependent on the rotor position. This paper presents the simulation of the open loop control of a 6/4 switched reluctance m...

Switched reluctance motor (SRM) is an energy converter that converts an electrical energy to mechanical energy in motoring operation and vice-versa in generating operation. When the rotor is out of alignment, the inductance is very low and the current also increase rapidly. The rotor is aligned with the stator then the inductance become very large. In the simulation results, how the rotor minim...

This document deals with solutions to control a switched reluctance motor using the TMS320C24x. This new DSP family enables cost-effective design of intelligent controllers for switched reluctance motors. Two speed control algorithms are presented, they allow the Switched Reluctance motor drive to reach high efficiency, smooth operation, very good dynamic behavior, very high speed and low acous...

Based on findings from two quite distinct research projects, this paper proposes that the reluctance of some teachers to make ICT an integral part of classroom teaching and learning is, at least partly, a consequence of several factors beyond their control. This reluctance occurs even though most teachers use one more forms of social networking as part of their out of classroom lifestyle. Two p...

Doubly salient wound field machines exhibit the advantages of robust structure and controllable flux, hence have been utilized as generators in applications automobiles renewable energy. However, inherent unbalanced phase back-electromotive force (EMF) waveform caused by asymmetric flux path brings difficulties for precise control smooth operation. To solve problem back-EMF conventional doubly ...

electric and hybrid electric vehicles are attractive candidates for sustainable transportation due to its higher efficiency and low emission. the critical choice on the electric motors is its capability of motoring and regenerative braking characteristics. switched reluctance machines are viable candidate as with proper control and extended constant power range operation replacing the multi-gea...
