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.
