GaN Transistors for Efficient Power Conversion (PDF)

Gallium nitride (GaN) is an emerging technology that promises todisplace silicon MOSFETs in the next generation of powertransistors. As silicon approaches its performance limits, GaNdevices offer superior conductivity and switching characteristics,allowing designers to greatly reduce system power losses, size,weight, and cost.

This timely second edition has been substantially expanded tokeep students and practicing power conversion engineers ahead ofthe learning curve in GaN technology advancements. Acknowledgingthat GaN transistors are not one-to-one replacements for thecurrent MOSFET technology, this book serves as a practical guidefor understanding basic GaN transistor construction,characteristics, and applications. Included are discussions on thefundamental physics of these power semiconductors, layout and othercircuit design considerations, as well as specific applicationexamples demonstrating design techniques when employing GaNdevices.

With higher-frequency switching capabilities, GaN devices offerthe chance to increase efficiency in existing applications such asDC-DC conversion, while opening possibilities for newapplications including wireless power transfer and envelopetracking. This book is an essential learning tool and referenceguide to enable power conversion engineers to designenergy-efficient, smaller and more cost-effective products usingGaN transistors.

Key features:
* Written by leaders in the power semiconductor field andindustry pioneers in GaN power transistor technology andapplications.
