GaN Transistors for Efficient Power Conversion

I was hoping for more information on the gate voltage shifting done to make the Dmode into Emode, and more on the optimization of the technology towards achieving best performance. This book is a little weak on the actual technology used in making eGAN FETs. There is a lot of application information about EPC devices. The book reads rather like an application note, which is typically free from most semiconductor vendors. Some of this book seems to be more marketing propaganda by EPC than an actual textbook or technical book about GAN transistors, but on the whole it would be very useful for designing a converter with EPC eGAN devices. There is a newer issue of this book, but it seemed to be very expensive.

The details of explaining the physics (as it pertains to the user) and, how to design power electronics using GaN could have been explained in less than 10 pages. I first scanned at random through a few pages. In one section he starts explaining how to design power supplies, along with his own bias which is not entirely correct. ("some cores may have higher loss at higher frequencies". Huh? No; MOST materials are frequency dependent, not "may be".) There are many books, from the likes of Ridley and Basso which lead the novice to understand power supply design.I found the reading pretty scattered and not to-the-point as I would have wanted.

It only cover one kind of substrate for GaN

Well written, concise, this book gave me several insights in to better utilization of GaN FETs'It is worth the money, especially if you are designing Power Conversion with GaN semiconductors.This book will however take 2-3 readings to get the full extents, quite deep in the coverage of teh subject.Nice read.

This book describes a major breakthrough in the design of power transistors. The authors thoroughly present the new Gallium Nitride type transistor starting with the basic physics and proceed to device characteristics, advantages relative to traditional Mosfets, detailed circuitry, reliability, mounting techniques, and commercial considerations. It is a practical Design Manual, and I recommend that it be absorbed by all involved in transistorized power design.Bill CollinsElectronic Design Engineer
