The SRM drive operates over the entire speed range and provides low torque ripple with smooth transition between the control operations. The low torque ripple is achieved by controlling the firing angles through simple formulas so as to minimize the pulsations of the total current in the commutation region. The smooth transition is attained since the conditions that determine the firing angles ...

This paper presents the design, and simulation of a soft switched boost converter for a switched reluctance motor with a closed loop controller. A soft switching scheme is proposed in the converter with minimum components, which reduces the switching loss and stress across the switch so that the harmonic generation is reduced in the output. The switch used in this converter switched ON at zero ...

The simple structure, low manufacturing cost, rugged behavior, high torque per unit volume and wide torquespeed range make switched reluctance motor (SRM) very attractive for industrial applications. However, these advantages are overshadowed by its inherent high torque ripple, acoustic noise, and difficulty to control. The controlled parameters in SRM drives can be selected as the turn-on angl...

The problem of torque tracking PI-controller design for switched reluctance motor (SRM) drive is discussed, where SRM magnetization characteristics are highly nonlinear, and torque is a complex and coupled function of phase current and rotor position. A distinctive feature of the control system designed is that two-time-scale motions are artificially forced in the closed-loop system by the sele...

The flux and torque of switched reluctance motor (SRM) have a highly nonlinear functional relationship with rotor position and phase current, as a consequence of the double-salient structure of the stator and rotor pole and highly magnetic saturation, which is difficult to build an accurate analytic model. In order to achieve the SRM high-performance control, it is necessary to build an accurat...

Although PSPICE is a powerful tool to simulate the circuits, it is a tough job to simulate the electromagnetic behavior of a converter-fed motor drive, particularly the switched reluctance motor (SRM) with many nonlinearities in its constituted components. Therefore, a simulation environment of the SRM drive combining the features of POWERSYS and SIMULINK is developed in this paper. In the esta...

Due to the growing demand for and growth in electric vehicle (EV) market a future civilization with advanced technology. Electric vehicles outperform traditional ones terms of performance. Because they are environmentally friendly, EVs can help create green sustainable environment. They provide convenience eco-friendliness that conventional cars cannot. Over past 20 years, switching reluctance ...

Switched Reluctance Motor is a rotating electric machine where both stator and rotor have salient poles.
