This book presents the transformational progress in next-generation advanced converter circuit topologies based on the unique electrical properties of wide-bandgap semiconductors, including silicon carbide (SiC) and gallium nitride (GaN). It addresses the opportunities for significant advances in power electronics circuit performance opened by the availability of wide-bandgap power devices and the challenges associated with using these devices that must be overcome when applying them. The authors tackle specific grand challenges in application areas covering a broad range of power electronics circuits and systems disciplines, including electric motor-driven systems, automotive applications, air/rail/ship propulsion, electric vehicle chargers, high-performance computing and data centers, power supplies, solar inverters, wind-electric systems, high/medium voltage transmission/distribution equipment and power electronics interacting with the grid, power conversion for grid storage, monolithic power processing, and solid-state circuit breakers. Wide Bandgap Power Electronics: Emerging Converter Technologies and Applications introduces readers to the unique characteristics of wide-bandgap power semiconductor devices and the revolutionary impact that they are capable of having on the performance of power converters in future power electronics applications and will be an invaluable resource for practicing engineers, researchers, and graduate students in the field of power electronics, applications, and systems.

This book offers an essential compendium on theanalysis and design of synchronous motors for variable-speed applications.Focusing on synchronous reluctance and ferrite permanent-magnet (PM)synchronous reluctance machines, it provides a broad perspective on three-phasemachines for variable speed applications, a field currently dominated byasynchronous machines and rare-earth PM synchronous machines. It also describessynchronous reluctance machines and PM machines without rare-earth materials,comparing them to state-of-the-art solutions. The book provides readers withextensive information on and finite element models of PM synchronous machines,including all relevant equations and with an emphasis on synchronous-reluctanceand PM-assisted synchronous-reluctance machines. It covers ferrite-assistedmachines, modeled as a subcase of PM-assistance, fractional slot combinationssolutions, and a quantitative, normalized comparison of torque capability withbenchmark PM machines. The book discusses a wealth of techniques foridentifying machine parameters, with an emphasis on self-commissioningalgorithms, and presents methods for automated machine design and optimization,including a software tool developed for this purpose. Addressing an importantgap in the field of PM-less and less-PM electrical machines, it is intended asa self-contained reference guide for both graduate students and professionalmachine designers, and as a useful text for university courses on automatedand/or optimized design of electrical machines and drives.
