Abstract

Preface In today's energy-dependent world, electrochemical devices for energy storage and conversion such as batteries, fuel cells and electrochemical supercapacitors (ES') have been recognized as the most important portion among all energy storage and conversion technologies. Electrochemical supercapacitor, also known as supercapacitor, ultracapacitor, or electrochemical double layer capacitor, is a special capacitor that can store relatively high energy density compared to conventional capacitor. Possessing a number of high-impact characteristics, such as fast charging, long charge-discharge cycles and broad operating temperature ranges, ES' have wide spread applications in hybrid or electrical vehicles, electronics, aircrafts, and smart grids. Although there are still some challenges in ES systems such as relatively low energy density and high cost at current technology state, with further development, ES' can not only in tandem with batteries and fuel cells serve as power devices, but also work as a standalone high energy storage device. To facilitate the research and development, we believe a book containing both fundamentals and applications of ES technology is definitely needed. The best known book in the field is B. E. Conway's Electrochemical Supercapacitor-Scientific Fundamentals and Technological Applications published in 1999. This book gives the first comprehensive illustration and summary of the development of electrochemical supercapacitor in 20th century. Our book will focus on the introduction to the electrochemical supercapacitors from more technical and practical aspects and crystallization of the technology development in the past decade--

Abstract

In this work we derive asymptotically stabilizing control laws for electrical power systems using two nonlinear control synthesis techniques. For this transient stabilization problem the actuator considered is a power electronic device, a controllable series capacitor (CSC). The power system is described using two different nonlinear models - the second order swing equation and the third order flux-decay model. To start with, the CSC is modeled by the injection model which is based on the assumption that the CSC dynamics is very fast as compared to the dynamics of the power system and hence can be approximated by an algebraic equation. Here, by neglecting the CSC dynamics, the input vector $g(x)$ in the open loop system takes a complex form - the injection model. Using this model, interconnection and damping assignment passivity-based control (IDA-PBC) methodology is demonstrated on two power systems: a single machine infinite bus (SMIB) system and a two machine system. Further, IDA-PBC is used to derive stabilizing controllers for power systems, where the CSC dynamics are included as a first order system. Next, we consider a different control methodology, immersion and invariance (I&I), to synthesize an asymptotically stabilizing control law for the SMIB system with a CSC. The CSC is described by a first order system. As a generalization of I&I, we incorporate the power balance algebraic constraints in the load bus to the SMIB swing equation, and extend the design philosophy to a class of differential algebraic systems. The proposed result is then demonstrated on another example: a two-machine system with two load buses and a CSC. The controller performances are validated through simulations for all cases.     .

Abstract

An increasing number of medical diagnostics, comfort, entertainment, and sports applications are making use of capacitive sensor systems in and around the body. These sensor systems should work as small distributed units that can collect data over a long period of time. So, ultra low power electronics are a major challenge in these applications. Ultra Low Power Capacitive Sensor Interfaces describes the design and theory of ultra low power capacitive sensor interfaces. The book’s major asset is the realization of a very low power generic sensor interface chip, that is adaptable to a broad range of capacitive sensors. The book starts with an overview on the most important design aspects for autonomous sensor systems. The different building blocks are discussed and the modular architecture for the generic sensor interface chip is presented. Furthermore, the design of the analog components, such as capacitance-to-voltage converters, switched capacitor amplifier, Sigma Delta modulator, oscillators and reference circuits, is described in more detail. Finally, the generic sensor interface chip is applied in several state-of-the-art pressure sensor and accelerometer applications. Ultra Low Power Capacitive Sensor Interfaces is essential reading for anybody with an academic or professional interest in semiconductor design.
