This work describes the design of a WPT transmitter connected to a planar coil, designed by EM simulation, for the near-field wireless power transfer (WPT) of 25 W at 27 MHz to an almost unknown receiving section. A class-E inverter in GaN technology has been adopted to achieve constant current condition and high performance for its load-independent operation. A careful control of the overall efficiency of the WPT systems is provided during the different steps of the optimization process. The manuscript highlights the importance of the realistic description of both the amplifier and the loop for the sake of the project reliability.

Abstract

This work describes the design of a WPT transmitter connected to a planar coil, designed by EM simulation, for the near-field wireless power transfer (WPT) of 25 W at 27 MHz to an almost unknown receiving section. A class-E inverter in GaN technology has been adopted to achieve constant current condition and high performance for its load-independent operation. A careful control of the overall efficiency of the WPT systems is provided during the different steps of the optimization process. The manuscript highlights the importance of the realistic description of both the amplifier and the loop for the sake of the project reliability.
