This paper presents the comparisons between two types of switched reluctance machines (SRMs) and SRM converters. An with a segmental rotor is compared conventional (CSRM), an converter containing passive boost circuit asymmetric half-bridge (AHB) converter. The has segmented structure. four segments are made steel laminations. Two misaligned other by 15 degrees. torque ripple this structure dec...

The study presents the development and implementation of a new sensorless algorithm for estimating the rotor position at a wide range of operating conditions. The algorithm is designed to overcome difficulties in estimating the rotor position at starting as well as at the normal operation region. The algorithm is successfully implemented experimentally using SRM fed from a photovoltaic source w...

This paper presents an advanced torque ripple minimization method of a switched reluctance motor (SRM) using torque sharing function (TSF). Generally, TSF is applied into the torque control. However, the conventional TSF cannot follow the expected torque well because of the nonlinear characteristics of the SRM. Moreover, the tail current that is generated at a high speed motor drive makes unexp...

Design and construction of a stable current supply with protection circuits are described. The reported circuit provides a high-stable and high-level current variable from 0.5-1.2 A with the protect ion circuits to prevent over load current, voltage and off-range temperature operation. A detailed analysis of the circuit parameters is given and the time behaviors of the load voltage/current and ...

Abstract— The Switched Reluctance Motor (SRM) drive has evolved as an alternative to conventional motors in variable speed drives because of advantages like simple and rugged structure, absence of rotor winding, adaptability to harsh environments and high speed operation. This paper presents the speed control of Asymmetrical converter fed 4 phase 8/6 Switched Reluctance Motor drive using PWM co...

Improving the behavior of speed control in electric vehicles is currently a major challenge for researchers and engineers. For this study, we chose context Switched Reluctance Motor (6/4 SRM) used hybrid Electric Vehicle with Extended Range (EREV). Speed regulation an essential feature on long-distance trip. regulators backstepping type are very effective given non-linear nature switched reluct...

An augmented system constructed based on reference signal and SRM model to allow solving algebraic Riccati equation current-tracking Thi...

=AbstractSingle-stage current-source charge-pump powerfactor-correction (SS CS-CPPFC) electronic ballast employs charge-pump concept to obtain high power factor with low cost. However, the circuit has a poor lamp current crest factor and large lamp output power variation, which deteriorates the lamp life. Feed-forward and/or feedback circuit are usually used to deal with these problems at the p...

The switched reluctance motor (SRM) is recently gaining huge popularity in electric vehicle (EV) applications due to its control flexibility, simple structure, lower cost and high efficiency than the synchronous induction motors. Among all controllers, direct torque (DTC) most preferred higher efficiency, losses superior characteristics. In this paper, a 6/4 pole SRM with fuzzy logic based DTC ...
