Radicals for Capitalism


Book Description

On Wall Street, in the culture of high tech, in American government: Libertarianism -- the simple but radical idea that the only purpose of government is to protect its citizens and their property against direct violence and threat -- has become an extremely influential strain of thought. But while many books talk about libertarian ideas, none until now has explored the history of this uniquely American movement -- where and who it came from, how it evolved, and what impact it has had on our country. In this revelatory book, based on original research and interviews with more than 100 key sources, Brian Doherty traces the evolution of the movement through the unconventional life stories of its most influential leaders -- Ludwig von Mises, F.A. Hayek, Ayn Rand, Murray Rothbard, and Milton Friedman -- and through the personal battles, character flaws, love affairs, and historical events that altered its course. And by doing so, he provides a fascinating new perspective on American history -- from the New Deal through the culture wars of the 1960s to today's most divisive political issues. Neither an expos' nor a political polemic, this entertaining historical narrative will enlighten anyone interested in American politics.

Wireless Power Transfer Technologies for Electric Vehicles


Book Description

This book introduces the most state-of-the-art wireless power transfer technologies for electric vehicles from the fundamental theories to practical designs and applications, especially on the circuit analysis methods, resonant compensation networks, magnetic couplers, and related power electronics converters. Moreover, some other necessary design considerations, such as communication systems, detection of foreign and living objects, EMI issues, and battery charging strategies, are also introduced to provide sufficient insights into the industrial applications. Finally, some future points are mentioned in brief. Different from other works, all the WPT technologies in this book are applied in real EV applications, whose effectiveness and reliability have been already tested and verified. From this book, readers who are interested in the area of wireless power transfer can have a broad view of modern WPT technologies. Readers who have no experience in the WPT area can learn the basic concept, analysis methods, and design principles of the WPT system for EV charging. Even for the readers who are occupied in this area, this book also provides rich knowledge on engineering applications and future trends of EV wireless charging.

Transformerless Photovoltaic Grid-Connected Inverters


Book Description

This book focuses on a safety issue in terms of leakage current, builds a common-mode voltage analysis model for TLIs at switching frequency scale and develops a new modulation theory referred as “Constant Common-Mode Voltage Modulation” to eliminate the leakage current of TLIs. Transformerless Grid-Connected Inverter (TLI) is a circuit interface between photovoltaic arrays and the utility, which features high conversion efficiency, low cost, low volume and weight. The detailed theoretical analysis with design examples and experimental validations are presented from full-bridge type, half-bridge type and combined topologies. This book is essential and valuable reference for graduate students and academics majored in power electronics; engineers engaged in developing distributed grid-connected inverters; senior undergraduate students majored in electrical engineering and automation engineering.
