Efficient Power Conversion Corp (EPC) of El Segundo, CA, USA, which makes enhancement-mode gallium nitride on silicon (eGaN) power field-effect transistors (FETs) for power management applications, has announced publication of the second edition of the 'Wireless Power Handbook'. This edition is a practical engineering handbook designed to provide power system design engineers with experiences and points of reference critical to understanding and designing highly efficient wireless power systems using GaN transistors.
As a supplement to EPC's 'GaN Transistors for Efficient Power Conversion', the updated and expanded practical guide provides step-by-step analysis on the use of GaN transistors in wireless power transfer systems. Topics covered include how to effectively compare component devices, such as eGaN FETs and MOSFETs, when used in an amplifier design. This comparison, complete with experimental verification, illustrates the superiority of eGaN FETs over MOSFETs in this high-performance application.
This second edition has been expanded to include the latest work on AirFuel Alliance class 2 and class 3 transmitters, adaptive tuning, radiated EMI, multi-mode wireless power systems, and control strategies. Also, wireless power systems are demonstrated using the latest eGaN FETs and integrated circuits that set new efficiency benchmarks as well as reduce overall system costs.
'Wireless Power Handbook: a Supplement to GaN Transistors for Efficient Power Conversion, 2nd Edition' is available for $39.95 and can be purchased from both Digi-Key and Amazon.com.
The author Michael de Rooij is EPC's VP of applications engineering. Prior to joining EPC, he worked at Windspire Energy and the GE Global Research Center. Dr de Rooij received his Ph.D. from the Rand Afrikaans University and conducted postdoctoral studies on power electronic integration, packaging and a high-frequency MOSFET gate-driver at the Center for Power Electronic Systems (CPES) at Virginia Tech. He is a senior member of the IEEE and has authored over 25 publications, most recently co-authoring 'GaN Transistors for Efficient Power Conversion'. He has been granted 21 US and International patents and 19 US and International pending patent applications.
