This book presents progress in device processing and materials characterization of the wide-bandgap semiconductor gallium nitride (GaN) and related materials for power electronics applications. The content of the book is based on the output of multiple well defined and actively managed programs from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E). The material is organized into eight parts with a total of 28 chapters contributed from invited experts that were part of the ARPA-E programs along with chapters from a few select experts from around the world who...

The lack of effective DC fault protection technology remains a major barrier for the DC paradigm shift. In addressing the key challenges,Direct Current Fault Protection: Basic Concepts and Technology Advancesstarts with an introduction to the advantages of DC power systems before moving on to an in-depth review of DC fault protection technologies, including mechanical circuit breaker (MCB), solid-state circuit breaker (SSCB), hybrid circuit breaker (HCB), converter based (breakerless) protection, and fault current limiter (FCL). Coverage includes a comprehensive comparison of various DC fault...
