An up-to-date and concise review of GaN transistor design and applications In the newly revised fourth edition of GaN Power Devices for Efficient Power Conversion, a team of distinguished researchers and practicing engineers deliver a concise and effective new guide to designing small, energy-efficient, and inexpensive products with GaN transistors. This new edition covers all relevant new GaN technology advancements, allowing students and practicing engineers to get, and stay ahead of, the curve with GaN device and circuit technology. You’ll explore applications including DC to DC converters, solar inverters, motor drive controllers, satellite electronics, and LiDAR devices. The 4th edition offers critical updates for space applications, vertical GaN, and driving transistors and integrated circuits. New chapters on reliability testing advancements, device wear out mechanisms, thermal management, and the latest developments in monolithic integration round out the book. Readers will also find: The latest updates on significant technology improvements, like integrated circuits, reliability studies, and new applicationsComprehensive explorations of integrated circuit construction, characteristics, reliability results, and applicationsPractical discussions of specific circuit designs, layout, and thermal dissipation when designing power conversion systemsChapters written by practicing expert leaders in the power semiconductor field and industry pioneers Perfect for practicing power conversion engineers, GaN Power Devices for Efficient Power Conversion will also benefit electrical engineering students and device scientists in the field of power electronics.

As a presidential candidate, Donald Trump broke not only from the Republican Party but also from the bipartisan consensus on the direction of recent U. S. foreign policy. Calling the Iraq war a terrible mistake and lamenting America's nation building expeditions, Trump evinced little interest in maintaining the traditional form of American leadership of the liberal international order. He threatened to pull the United States out of NATO, complained that the United States was being taken advantage of by its trading partners, and argued that immigration was a terrible threat. Instead, Trump's "America First" vision called for a reassertion of American nationalism on the economic front as well as in foreign affairs. Since Trump took office, it has become clear that "America First" was more campaign slogan than coherent vision of American grand strategy and foreign policy. As president Trump has steered a course that has maintained some of the worst aspects of previous foreign policy - namely the pursuit of primacy and frequent military intervention - while managing to make a new set of mistakes all his own. This book provides an assessment of Trump's America First doctrine, its performance to date, and its implications for the future.
