This book was much more difficult to write than the first book, Robot Building for Beginners, Second Edition (Apress, 2010). In the first book, I assume the reader knows nothing about electronics or machining. That neatly limits the book’s subjects to the trunk of the “robot tree of knowledge.” But a funny thing happens after that. Robots are so diverse in their capabilities and purposes that the robot tree of knowledge explodes with braches in all sorts of directions after you understand the basics. Therefore, it’s impossible to select a single type of robot that all intermediate builders want to make. Upon being armed with (almost) enough knowledge, each builder is already heading down his or her own unique path. Therefore, this book is about how to grow a robot, not what type of robot to grow.

This book on power electronics spans a wide knowledge base such as power devices, drives, circuit topologies, magnetics, system modeling, control configurations, digital processing, thermal and reliability aspects. The book has been broadly divided into two types of topics viz. (a) circuit-oriented aspects and (b) system-oriented aspects. The first seven chapters deal with circuit-oriented aspects of power electronics systems and the remaining chapters deal with system-oriented aspects like controls and reliability. Table of contents power semiconductor switches drive circuits rectifiers dc-dc linear regulators dc-dc switched-mode converters dc-ac switched-mode converters design of magnetics modeling of systems control system essentials optimal and robust controller design discrete computation essentials thermal aspects reliability modeling reliability prediction.

Язык: English

This book describes a cross-domain architecture and design tools for networked complex systems where application subsystems of different criticality coexist and interact on networked multi-core chips. The architecture leverages multi-core platforms for a hierarchical system perspective of mixed-criticality applications. This system perspective is realized by virtualization to establish security, safety and real-time performance. The impact further includes a reduction of time-to-market, decreased development, deployment and maintenance cost, and the exploitation of the economies of scale through cross-domain components and tools.
