GAN FET BOOK-WIPO

Page 1 of 1 Wireless Power Handbook A Supplement to GaN Transistors for Efficient Power Conversion Michael A. de Rooij 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.
