Available in PDF, EPUB and Kindle. Book excerpt: This book describes two target applications for synchronous systems: regulated 3-phase voltage supply and voltage sag mitigation. It presents a detailed design procedure for converter switches and filters considering all steady-state, commutation and dynamic requirements. This work has evolved from previously published research by the authors, which in turn is part of a larger effort to expand the application domain of matrix converters to power systems. The objectives of the work have been categorized into the following: developing a dynamic model that provides adequate design insights; designing filters; and devising a control scheme. The low frequency dynamic model is first analyzed for regulated voltage supplies assuming balanced system. The system is modeled relative to a synchronous rotating (dq) frame linearized around an operating point. The input–output variables are related by non-diagonal transfer function matrices. Individual transfer function sub-matrices are sequentially investigated and it is shown that, depending on the input power, input voltage and filter parameters, the appearance of a set of right half zeros is possible. The book then considers filter design, as well as general issues like ripple attenuation, regulation, reactive current loading, and filter losses. The book also addresses additional constraints that may be imposed by dynamic requirements and commutation. In the third stage, voltage controller design is detailed for a 3-phase regulated voltage supply. In dq domain, output voltage control represents a multivariable control problem. This is reduced to a single variable control problem while retaining all possible right half zeros, thereby preserving the internal stability of the system. Consequently, the standard single variable control design technique has been used to design a controller. The analytically predicted dynamic response has been verified by experimental results. It was possible to operate the system beyond the critical power boundary where the right half zeros emerge. Lastly, the developed control approach has been extended to voltage sag mitigation with adequate modifications. A 3-wire linear load and both symmetrical and asymmetrical voltage sags have been considered. Experimentally obtained response time for sag mitigation was found to be less than the power supply holdup time of most of the sensitive equipment. This book will be useful to both researchers and graduate students.

This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power electronics is the key technology for connecting flexible ac transmission system devices and renewable power generation to the ac grid. Among the ac to ac converters, the matrix converter represents a promising alternative power electronics technology to back to back converters. It does not incorporate any storage elements which minimises the size and weight of the converter. In addition, with the introduction of the reverse blocking insulated gate bipolar transistor, its efficiency can surpass that of back to back converters. A new approach in controlling the matrix converter output current is introduced. The approach depends mainly on logic circuitry and facilitates power system applications using the matrix converter. Furthermore, it can provide sinusoidal output current under asymmetry voltage conditions. The output current quality is at the expense of the input current in this case. Both sinusoidal input and output currents cannot be achieved under asymmetry voltage conditions due to the lack of any storage elements. Matrix converter suitability to power system applications such as flexible ac transmission and embedded generation, is investigated particularly under asymmetrical ac supply conditions. The effect of the absence of an intermediate storage element, on the output power and current quality is considered. The utilization of the proposed control technique in a unified power flow controller, which is the most versatile flexible ac transmission system device, is investigated. The restriction on unified power flow controller operation due to the absence of any intermediate storage element in the matrix converter is also studied. Special attention is given to asymmetry ac voltage condition effects and how to mitigate this problem for embedded generation. Extraction of the positive and negative sequence components is essential in obtaining non-oscillatory output power, and a dual current controller is used to this end.

This book was released on 2013-02-28 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: AC voltage frequency changes is one of the most important functions of solid state power converters. The most desirable features in frequency converters are the ability to generate load voltages with arbitrary amplitude and frequency, sinusoidal currents and voltages waveforms; the possibility of providing unity power factor for any load; and, finally, a simple and compact power circuit. Over the past decades, a number of different frequency converter topologies have appeared in the literature, but only the converters with either a voltage or current DC link are commonly used in industrial applications. Improvements in power semiconductor switches over recent years have resulted in the development of many structures of AC-AC converters without DC electric energy storage. Such converters are an alternative solution for frequently recommended systems with DC energy storage and are characterized by a lower price, smaller size and longer lifetime. Most of the these topologies are based on the structure of the matrix converter. Three-Phase AC-AC Power Converters Based On Matrix Converter Topology: Matrix-reactance frequency converters concept presents a review of power frequency converters, with special attention paid to converters without DC energy storage. Particular attention is paid to nine new converters named matrix-reactance frequency converters which have been developed by the author and the team of researchers from Institute of Electrical Engineering at the University of Zielona Góra. The topologies of the presented matrix-reactance frequency converters are based on a three-phase unipolar buck-boost matrix-reactance chopper with source or load switches arranged as in a matrix converter. This kind of approach makes it possible to obtain an output voltage greater than the input one (similar to that in a matrix-reactance chopper) and a frequency conversion (similar to that in a matrix converter). Written for researchers and Ph.D. students working in the field of power electronics converters and drive systems, Three-Phase AC-AC Power Converters Based On Matrix Converter Topology: Matrix-reactance frequency converters concept will also be valuable to power electronics converter designers and users; R&D centers; and readers needing industry solutions in variable speed drive systems, such as automation and aviation.

Available in PDF, EPUB and Kindle. Book excerpt: Matrix converter is a direct AC-AC converter topology that is able to directly convert energy from an AC source to an AC load without the need of a bulky and limited lifetime energy storage element. Due to the significant advantages offered by matrix converter, such as adjustable power factor, capability of regeneration and high quality sinusoidal input/output waveforms, matrix converter has been one of the AC Â- AC topologies that receive extensive research attention for being an alternative to replace traditional AC-DC-AC converters in the variable voltage and variable frequency AC drive applications. Multilevel matrix converter is an emerging topology that integrates the multilevel concept into the matrix converter topology. Having the ability to generate multilevel output voltages, the multilevel matrix converter is able to produce better quality output waveforms than conventional matrix converter in terms of harmonic content, but at the cost of higher number of power semiconductor device requirement and more complicated modulation strategy. In this research work an indirect three-level sparse matrix converter is proposed. The proposed converter is a hybrid combination between a simplified three-level neutral-point-clamped voltage source inverter concept and an indirect matrix converter topology. This multilevel matrix converter topology has a simpler circuit configuration and is able to generate three-level output voltages, making this topology an attractive option in industrial applications. In this work a comprehensive simulation study is carried out to investigate the operation of the proposed converter. The performance of the proposed converter is compared to the conventional indirect matrix converter topology and a multilevel neutral-point- clamped matrix converter in order to identify the advantages and disadvantages offered by the proposed converter. A study of the semiconductor losses in the indirect three-level sparse matrix converter is also included. Finally, the operation of the proposed converter is experimentally validated using a laboratory prototype.
