Book excerpt: Ayna could predict the future. Cari could find what was lost. Gair thought he was ordinary. The three children of Gest, the chief of Garholt, know the perils of the Moor on which they live. The Dorig, their people's enemies, are cold-blooded, fierce underwater creatures who terrify anyone unlucky enough to happen upon them. The Giants are dangerous and violent. But it's not until their home is invaded that Gair learns of a dying curse that endangers all three peoples of the Moor. A curse that ordinary Gair, with the help of his extraordinary brother and sister, may be able to break, but only at the most dreadful risk to all three, and to the Moor itself.

The wild cats have flourished in their new home on the banks of the lake for several seasons, and the Clans are growing strong and healthy with new kits. The time has come for three kits of ThunderClan to become apprentices. Hollypaw, Jaypaw, and Lionpaw spring from a strong legacy: children of Squirrelflight and Brambleclaw, two of the noblest ThunderClan warriors, and grandchildren of the great leader Firestar himself. All three young cats possess unusual power and talent and seem certain to provide strength to the Clan for the next generation. But there are dark secrets around the three, and a mysterious prophecy hints at trouble to come. An undercurrent of rage is rising against those who are not Clanborn, and the warrior code is in danger of being washed away by a river of blood. All the young cats' strength will be needed if the Clans are to survive. . . . who hold the power of the stars in their paws.

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.
