Book Optimal Control of Matrix Converters Under Distorted and Unbalanced Supply Conditions

Download or read book Optimal Control of Matrix Converters Under Distorted and Unbalanced Supply Conditions written by Coneth Graham Richards and published by . This book was released on 2013 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: A matrix converter is a forced commutated converter which uses an array of controlled bi-directional switches as the main power processing elements to create a variable voltage system with unrestricted frequency. It does not contain any DC link circuit and does not require any large energy storage elements. The output frequency is theoretically infinitely variable as opposed to cyclo-converters. This study will evaluate present modulation techniques for matrix converters. Chapter 2 will review the present direct and indirect modulation techniques for Matrix Converters. Chapter 3 develops the indirect modulation model, based on space vector modulation techniques. In chapter 4 various state space models are developed and an optimised switching pattern, based on the least square error, is developed.

Book Optimal Control and Appliation of AC AC Matrix Converters

Download or read book Optimal Control and Appliation of AC AC Matrix Converters written by Chaiypat Watthanasarn and published by . This book was released on 1997 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis presents the development of real-time control techniques for direct AC-AC matrix converters. Principles and performance characteristics of two pulse-width modulation methods;' the Venturini and Space Vector Modulation algorithms, are thoroughly explored. Comparative studies of the methods in several important aspects are performed, leading to the construction of a DSP-controlled high harmonic performance and low power loss matrix converter suitable for AC drives. The indisputable benefits of a matrix converter are further demonstrated by applying it successfully to the rotor current control of a computer-simulated wind-turbine driven doubly-fed induction generator. While investigating the two PWM methods, a novel technique for the Venturini scheme has been developed which compensates the effects of the supply voltage distortion and/or unbalance. For the SVM method, a new procedure for input displacement angle control has been derived. Comparison of the two methods' relative performances is made with regard to operation under unbalanced/distorted supply voltage, output voltage and input current harmonics, and converter losses........

Book Three phase AC AC Power Converters Based on Matrix Converter Topology

Download or read book Three phase AC AC Power Converters Based on Matrix Converter Topology written by Paweł Szcześniak and published by Springer Science & Business Media. 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: The authors were originally brought together to share research and applications through the international Danfoss Professor Programme at Aalborg University in Denmark. Personal computers would be unwieldy and inefficient without power electronic dc supplies. Portable communication devices and computers would also be impractical. High-performance lighting systems, motor controls, and a wide range of industrial controls depend on power electronics. In the near future we can expect strong growth in automotive applications, dc power supplies for communication systems, portable applications, and high-end converters. We are approaching a time when all electrical energy will be processed and controlled through power electronics somewhere in the path from generation to end use. - The most up-to-date information available is presented in the text - Written by a world renowned leader in the field
