This book was released on 2016 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis is to improve the high speed range of a switched reluctance motor (SRM). An auto-transformer-like winding is proposed to achieve fast demagnetization of phase windings for better high speed performance. The re-configured winding requires the development of a new power converter to drive the motor. The developed converter applies the DC bus voltage across a portion of the phase winding during the demagnetization time interval. Accordingly, a higher negative demagnetization voltage is applied, leading to a faster discharge rate of the phase excitation currents. Theoretical analysis of the proposed motor is presented to validate the effectiveness of the proposed demagnetizing technique. The proposed concept is verified through simulation using Finite Element Analysis and experimental tests on a rewound motor. A detailed comparison between the simulation and experimental results of the original and the rewound motors is given to highlight the advantages and the disadvantages of the proposed concept.

Download or read book Switched Reluctance Motor Drives written by R. Krishnan and published by CRC Press. This book was released on 2017-12-19 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: The switched reluctance machine (SRM) is the least expensive electrical machine to produce, yet one of the most reliable. As such, research has blossomed during the last decade, and the SRM and variable drive systems using SRMs are receiving considerable attention from industry. Because they require a power electronic converter and controller to function, however, successful realization of an SRM variable drive system demands an understanding of the converter and controller subsystems and their integration with the machine. Switched Reluctance Motor Drives provides that understanding. It presents a unified view of the machine and its drive system from all of its system and subsystem aspects. With a careful balance of theory and implementation, the author develops the analysis and design of SRMs from first principles, introduces a wide variety of power converters available for driving the SRM, and systematically presents both low- and high-performance controllers. The book includes an in-depth study of acoustic noise and its minimization along with application examples that include comparisons between ac and dc drives and SRM drive. The result is the first book that provides a state-of-the-art knowledge of SRMs, power converters, and their use with both sensor-based and sensorless controllers. Switched Reluctance Motor Drives enables both students and engineers to learn all aspects of SRM drive systems and appreciate the interdependence of the various subsystems in performance optimization.

Download or read book Multi functional Converter for Three phase Motor Drives written by Xiaokang Zhang and published by . This book was released on 2022 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on a two-level voltage-source-inverter fed three-phase permanent magnet synchronous machine drive which integrates an equivalent direct current (DC)/DC boost function by utilizing the machine's neutral point (NP). Such a drive system is referred to as multi-functional converter system (MFCS), and can be a promising alternative to the two-stage converter-based electric traction system in electric vehicles. First, to clearly reveal the mechanism, the average model of the basic MFCS is built. Then, different equivalent circuits are developed to explain the integrated boost function. Due to the conducting of the zero-sequence circuit, a specified modulation method named zero-sequence voltage injected pulse-width modulation is proposed. Second, to improve the basic MFCS, two new variants named MFCS-I and MFCS-II are further proposed. For the former, it employs a series inductor to suppress the current ripple. For the latter, it employs an auxiliary inverter leg to improve the effective step-up ratio. To control different MFCSs, a universal control strategy is proposed where the classic field-oriented control can still be used to control the motor function and a differential flatness-based controller is used to regulate the DC-bus voltage. Third, considering the innately connected NP in the MFCS-I, its fault-tolerant potential against an open-phase fault is explored for the first time. To this end, three constraints are found to achieve the fault-tolerant possibility. Then, a novel post-fault current vector trajectory is proposed which contributes to a constant torque and a stable average DC-bus voltage in post-fault conditions. Finally, the effectiveness of above ideas and control strategies is verified on experimental platforms.

This book was released on 2016-04-28 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an essential compendium on the analysis and design of synchronous motors for variable-speed applications. Focusing on synchronous reluctance and ferrite permanent-magnet (PM) synchronous reluctance machines, it provides a broad perspective on three-phase machines for variable speed applications, a field currently dominated by asynchronous machines and rare-earth PM synchronous machines. It also describes synchronous reluctance machines and PM machines without rare-earth materials, comparing them to state-of-the-art solutions. The book provides readers with extensive information on and finite element models of PM synchronous machines, including all relevant equations and with an emphasis on synchronous-reluctance and PM-assisted synchronous-reluctance machines. It covers ferrite-assisted machines, modeled as a subcase of PM-assistance, fractional slot combinations solutions, and a quantitative, normalized comparison of torque capability with benchmark PM machines. The book discusses a wealth of techniques for identifying machine parameters, with an emphasis on self-commissioning algorithms, and presents methods for automated machine design and optimization, including a software tool developed for this purpose. Addressing an important gap in the field of PM-less and less-PM electrical machines, it is intended as a self-contained reference guide for both graduate students and professional machine designers, and as a useful text for university courses on automated and/or optimized design of electrical machines and drives.
