Modern Electrical Drives
Electrical drives lie at the heart of most industrial processes and make a major contribution to the comfort and high quality products we all take for granted. They provide the controller power needed at all levels, from megawatts in cement production to milliwatts in wrist watches. Other examples are legion, from the domestic kitchen to public utilities. The modern electrical drive is a complex item, comprising a controller, a static converter and an electrical motor. Some can be programmed by the user. Some can communicate with other drives. Semiconductor switches have improved, intelligent power modules have been introduced, all of which means that control techniques can be used now that were unimaginable a decade ago. Nor has the motor side stood still: high-energy permanent magnets, semiconductor switched reluctance motors, silicon micromotor technology, and soft magnetic materials produced by powder technology are all revolutionising the industry. But the electric drive is an enabling technology, so the revolution is rippling throughout the whole of industry.
Reviving the Renaissance
This book offers an account of neo-Renaissance taste and style in Italy during the second half of the nineteenth century. By the time Italy had developed its obsession with the neo-Renaissance in the 1870s, collectors and scholars in the rest of Europe had been excited by Renaissance taste and style for several decades. In Italy the Renaissance was promptly reconceptualised, in a forced alignment with the accepted historical version of its birth and development, and its help enlisted in the search for an Italian national identity. But what represented this neo-Renaissance in Italy, and what aided its diffusion? In an attempt to answer these questions this book explores the many areas marked by neo-Renaissance taste. It traces its diffusion and development from the institutions which instructed its chief exponents, to architecture and exhibitions and the publications which disseminated neo-Renaissance designs so effectively.
Design, Control, and Harmonic Compensation for Stand-Alone and Grid-Connected Voltage-Source Converters: Simulation and Experimental Validations
Voltage source converters (VSCs), among other power converters, play a crucial role in supplying power to both local loads and the grid at the PCC. During stand-alone operation, VSCs ensure stable power for loads by regulating the output voltage. In grid-connected mode, the regulation shifts to controlling output current, such as converter side current (CSC) or grid side current (GSC), to inject sinusoidal current into the electrical grid. The nonlinear characteristics of the loads connected to the power converters result in significantly distorted output voltages. This capability is crucial for applications such as uninterruptible power supply (UPS), emphasizing the importance of precise ou...
Technological Innovation for Sustainability
This book constitutes the refereed proceedings of the Second IFIP WG 5.5/SOCOLNET Doctoral Conference on Computing, Electrical and Industrial Systems, DoCEIS 2011, held in Costa de Caparica, Portugal, in February 2011. The 67 revised full papers were carefully selected from numerous submissions. They cover a wide spectrum of topics ranging from collaborative enterprise networks to microelectronics. The papers are organized in topical sections on collaborative networks, service-oriented systems, computational intelligence, robotic systems, Petri nets, sensorial and perceptional systems, sensorial systems and decision, signal processing, fault-tolerant systems, control systems, energy systems, electrical machines, and electronics.
