Gebundene Ausgabe. Zustand: Neu. Primary and secondary solar concentrators are of vital importance for advanced solar energy and solar laser researches. Some of the most recent developments in primary and secondary solar concentrators were firstly presented. A novel three-dimensional elliptical-shaped Fresnel lens analytical model was put forward to maximize the solar concentration ratio of Fresnel-lens-based solar concentrators. By combining a Fresnel lens with a modified parabolic mirror, significant improvement in solar laser efficiency was numerically calculated. A fixed fiber light guide system using concave outlet concentrators was proposed. The absence of a solar tracking structure highlights this research. By shaping a luminescent solar concentrators in the form of an elliptic array, its emission losses was drastically reduced. Simple conical secondary concentrator was effective for thermal applications. New progresses in solar-pumped lasers by NOVA University of Lisbon were presented. By adopting a rectangular fused silica light guide, 40 W maximum solar laser power was emitted from a single Ce:Nd:YAG rod. An aspheric fused silica secondary concentrator and a small diameter Ce:Nd:YAG rod were essential for attaining 4.5 % record solar-to-laser power conversion efficiency. A novel solar concentrator design for the efficient production of doughnut-shaped and top-hat solar laser beams were also reported. More importantly, a novel solar concentrator approach for the emission of 5 kW-class TEM00 mode solar laser beams from one megawatt solar furnace was put forward at the end of this book, revealing promising future for solar-pumped lasers.

Hardback. Zustand: New. The electrification of the economy entails the development and optimization of efficient electrical machines. Permanent magnet machines use permanent magnets, rather than windings, for field excitation. They are more efficient than other electrical machine technologies for high-efficiency applications. Multiphase machines, as compared to 3-phase machines, have advantages including lower torque pulsation, higher power density, and better fault tolerance. This book offers concise and systematic coverage of multiphase permanent magnet machines and control techniques. It gives an overview of multiphase machines and control techniques in the context of various electrical machine technologies and presents the advantages of multiphase electrical machines. Applications are covered, including wind turbine generators, electric vehicles, electric ships, and aircraft and train propulsion. Machine topologies, modelling, design, control, pulse-width modulation, fault-tolerance, and reduction of current harmonics and torque ripples are considered. Multiphase Permanent Magnet Synchronous Machines and Drives: Principles, design, and control is written for industrial engineers and researchers, including PhD and post-doctoral research students working on electrical machines and drives, as well as for researchers working on electric vehicles, wind power generators, aerospace, electric ships and trains. Following a general introduction, chapters cover winding configurations, multiphase and dual-three-phase permanent magnet synchronous machines (PMSMs), modelling, design, modulation strategies, field-oriented control, direct torque control, model reference control, sensorless control, and also fault tolerant control for multiphase PMSMs. The logical progression from fundamental concepts to state-of-the-art research outcomes helps readers understand and use multiphase electrical machines.…
