This textbook provides power system design engineers basic technical and application-focused information on how to design more efficient power conversion systems using gallium nitride-based transistors. As a practical guide for power systems design engineers, it provides insights on the use of GaN transistors in power electronics applications, ranging from buck converters to Power over Ethernet.Also included are discussions on fundamental power engineering subjects such as; performance characteristics of GaN transistors, layout considerations for GaN circuits, paralleling GaN transistors and driver IC requirements for GaN transistors. The final chapters address GaN device reliability, their exceptional radiation-resistant characteristics as well as their future in power electronics.

Since Nikola Tesla first experimented with wireless power, there has been a quest to cut the cord of electrical power and go wireless! Now, over 100 years later, we finally have the technological capability to achieve Tesla's vision.
 Highly-resonant wireless power transfer, based on the generation of magnetic fields, has proven to be a viable path. Magnetic fields offer the necessary requisites ease of use, robustness and, most importantly are considered safe.
 A major challenge for implementing wireless power is the design of the amplifier. From experimental results presented in this book, it is clear that the ZVS Class D topology, fitted with eGaN power transistors provides the best solution. With their low capacitance, zero reverse recovery, and low on-resistance, eGaN FETs ensure low operating losses leading to higher amplifier efficiency and help keep EMI generation low. These devices have a very small footprint and low profile, which is important for mobile and medical applications.
 Understanding the many challenges to designing an amplifier for wireless power, such as radiated EMI, multi-mode systems and ways to improve efficiency is the aim of this handbook.

This second edition comes less than a year following the release of the first edition this is the pace at which the understanding and application of wireless power transfer is moving. Cut the cord is the battle cry and now that we know it can be done, what s holding us back, let s pick up speed and get on with it!
 The scope of this second edition has expanded to include the latest work on A4WP class 2 and class 3 transmitters, adaptive tuning, radiated EMI, multi-mode wireless power systems, and control strategies. There are also systems demonstrated using the latest in eGaN FETs and integrated circuits that set new efficiency benchmarks as well as reduce system costs.
 There is still much more to accomplish as this fast moving technology evolves; the purpose of this second edition is to share the latest information on the subject.
