Book excerpt: INTRODUCTION 1.1 GENERAL Matrix Converters (MC) are essentially 4-quadrant forced commutated converter and are formed by connecting a bi-directional switch cells in a matrix form. They are capable of fabricating an arbitrary output the voltage of variable frequency and magnitude. Factors like single stage transformation of voltage and frequency, bi-directional power flow capability, sinusoidal input and output voltage, more compact size, low weight, and DC link-free architecture, make this converter more attractive than a standard two stage converter.

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 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.

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.

Download or read book Boost Matrix Converters in Clean Energy Systems written by Ekrem Karaman and published by . This book was released on 2014 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes an investigation of novel power electronic converters, based on the ultra-sparse matrix topology and characterized by the minimum number of semiconductor switches. The Z-source, Quasi Z-source, Series Z-source and Switched-inductor Z-source networks were originally proposed for boosting the output voltage of power electronic inverters. These ideas were extended here on three-phase to three-phase and three-phase to single-phase indirect matrix converters. For the three-phase to three-phase matrix converters, the Z-source networks are placed between the three-switch input rectifier stage and the output six-switch inverter stage. A brief shoot-through state produces the voltage boost. An optimal pulse width modulation technique was developed to achieve high boosting capability and minimum switching losses in the converter. For the three-phase to single-phase matrix converters, those networks are placed similarly. For control purposes, a new modulation technique has been developed. As an example application, the proposed converters constitute a viable alternative to the existing solutions in residential wind-energy systems, where a low-voltage variable-speed generator feeds power to the higher-voltage fixed-frequency grid. Comprehensive analytical derivations and simulation results were carried out to investigate the operation of the proposed converters. Performance of the proposed converters was then compared between each other as well as with conventional converters. The operation of the converters was experimentally validated using a laboratory prototype.
