  • Control Circuits in Power Electronics: Practical issues in design and implementation
  • Control circuits are a key element in the operation and performance of power electronics converters. This book describes practical issues related to the design and implementation of these control circuits, with a focus on the presentation of the state-of-the-art control solutions, including circuit technology, design techniques, and implementation issues. Topics covered include PWM-based sliding mode control schemes for DC-DC power converters; synthetic-ripple hysteretic controllers for DC/DC converters; one-cycle controlled single phase power inverters; digital PWM control of high-frequency DC-DC switched-mode power converters; microcontroller-based electronic ballasts for high-intensity-discharge lamps; FPGA-based controllers for direct sliding mode control of PWM boost rectifiers; DSP controllers for three-phase unity-power-factor rectifiers and voltage-sourced inverters; FPGADSP controllers for DC-DC converters in renewable energy applications; topologies, modulation and control of multilevel converters; state-of-the-art intelligent gate drivers for IGBT power modules; control of integrated switched capacitor power converters; DSP-based natural frame control schemes for three-phase unity-power-factor rectifiers; dual-core DSP for control and communication in AC microgrids; and the use of computational intelligence for designing power electronics converters.

  • Nano-Scaled Semiconductor Devices: Physics, Modelling, Characterisation, and Societal Impact
  • The subject of nano-scaled semiconductor devices and technology is a strategic and emerging area of relevant societal importance in our ubiquitous electronics era. This book is intended for scientists, engineers, and graduate students involved in the research, technology development, education activities, and societal-related applications where nano-scaled semiconductor devices are involved. With the rapid evolution of the integrated circuit technology many new materials and fabrication processing steps have been incorporated. These new materials and processing steps enhance the electrical performance of nano-scaled semiconductor devices, resulting in faster, more functional and complex electronics. However, this boosted capacity comes with second-order effects that degrade device performance, impact its longterm reliability, energy-efficiency and ultimately contribute to worldwide energy waste and subsequent pollution. The characterization, modeling, and simulation prediction of these second-order effects is strongly correlated to each other. Therefore, this book, in a novel approach, attempts to blend the technology fabrication, with the characterization, physics, and modeling in a synergistic manner. For instance, the shrinkage of the device dimensions down to 14 nm and below pose a big challenge for the development of appropriate transport modeling mechanisms, which in turn require advanced characterization and modeling techniques. The characterization techniques, developed for studying transport in nano-scaled devices, is also a novel contribution of this book. Blending the characterization, modeling, physics, and technology is quite relevant for achieving energy-efficient electronics. Moreover, there is a benefit that device developers can get out from the complex nano-scaled semiconductor device technologies. This is also a topic that this book covers. The potential use of these new materials and structures for the development of new and alternative devices or functions, such as water decontamination, energy renewal, physiology research, energy-efficient milk and meat production, or optimal and energy-efficient crop irrigation. This book also correlates the fundamental physics and device electrical performance with energy efficiency, energy savings, and thus contributes to the development of a greener and more sustainable world.

image of Nano-CMOS and Post-CMOS Electronics: Circuits and Design
  • Nano-CMOS and Post-CMOS Electronics: Circuits and Design
  • The demand for ever smaller and portable electronic devices has driven metal oxide semiconductor-based (CMOS) technology to its physical limit with the smallest possible feature sizes. This presents various size-related problems such as high power leakage, low-reliability, and thermal effects, and is a limit on further miniaturization. To enable even smaller electronics, various nanodevices including carbon nanotube transistors, graphene transistors, tunnel transistors and memristors (collectively called post-CMOSdevices) are emerging that could replace the traditional and ubiquitous silicon transistor. This book explores these nanoelectronics at the circuit and systems levels including modelling and design approaches and issues. Topics covered include self-healing analog and radio frequency circuits; on-chip gate delay variability measurement in scaled technology node; nanoscale finFET devices for PVT aware SRAM; data stability and write ability enhancement techniques for finFET SRAM circuits; low-leakage techniques for nanoscale CMOS circuits; thermal effects in carbon nanotube VLSI interconnects; lumped electro-thermal modeling and analysis of carbon nanotube interconnects; high-level synthesis of digital integrated circuits in the nanoscale mobile electronics era; SPICEless RTL design optimization of nanoelectronic digital integrated circuits; green on-chip inductors for threedimensional integrated circuits; 3D network-on-chips; and DNA computing. This book is essential reading for researchers, research-focused industry designers/developers, and advanced students working on next-generation electronic devices and circuits.

  • Power Distribution Automation
  • Utilities around the world are under increasing pressure to provide reliable and good quality power supply to their retail customers, and to reduce their operational costs. These concerns call for real time monitoring and control of the distribution system, which can be accomplished by deploying distribution automation (DA) systems, a key enabling technology for smart grids. This book provides a detailed description of all the major components of a DA system, including communication infrastructure and analysis tools. Topics covered include communication systems for distribution automation; load flow analysis; short circuit analysis; state estimation; feeder reconfiguration for loss reduction, service restoration, and load balancing; volt-var control; fault location; fault type identification; and economic analysis/cost benefit analysis. Concluding with an international case study (Enexis, one of the major Distribution System Operators in The Netherlands) showing how DA has been implemented in practice, this book is essential reading for researchers and advanced students working in power engineering and practitioners engaged in distribution automation, such as utility engineers, vendors, and consultant

image of Recent Trends in Sliding Mode Control
  • Recent Trends in Sliding Mode Control
  • In control theory, sliding mode control, or SMC, is a nonlinear control method that alters the dynamics of a nonlinear system by application of a discontinuous control signal that forces the system to "slide" along a crosssection of the system's normal behavior. This book describes recent advances in the theory, properties, methods and applications of SMC. The book is organised into four parts. The first part is devoted to the design of higher-order sliding-mode controllers, with specific designs presented in the context of disturbance rejection by means of observation and identification. The second part offers a set of tools for establishing different dynamic properties of systems with discontinuous right-hand sides. Time discretization is addressed in the third part. First-order sliding modes are discretized using an implicit scheme - higher-order slidingmode differentiators, typically used in output-feedback schemes, are discretized in such a way that the optimal accuracy of their continuous-time counterparts is restored. The last part is dedicated to applications. In the context of energy conversion, sliding-mode control is applied to variable-speed wind turbines, fuel cell coupled to a power converter, rugged DC series motors and rectifiers with unity power factor, and electropneumatic actuator. Finally, an event-triggered sliding-mode scheme is proposed for networked control systems subject to packet loss, jitter and delayed transmissions.
