GaN class E Wireless Power Transfer system: a new design method relying on the advanced modeling of parasitic elements

Résumé

This paper reports the design, the simulation and the characterization of a 13.56 MHz inductive coupling wireless power transfer (WPT) system based on a GaN class E inverter. The main benefit of a class E WPT system is the small amount of components needed while achieving good efficiency. An analytical model of the system is proposed and a new design method centered on the coupler and taking parasitic elements into account through advanced modelling is reported. The fabricated system shows an efficiency of 76 % for a transmitted power of 3.4 W and the mismatch for the efficiency between advanced modeling and experimental results is around 4%.
