Advances in Power and RF Electronics - Near- / far- field wireless power transfer

ABSTRACT

The course aims at providing the main design rules and approaches for realizing both Near- and Far-field wireless power transfer (WPT) systems, and the main differences between them  will be clarified, by focusing on the transmitter and receiver architectures and on the wireless link characteristics.
In the far-field case the attention will be mainly focused on the proper selection of smart RF energy source. Two promising families of highly-reconfigurable arrays will be presented as powerful tools for selective WPT, through their peculiar radiation capabilities: time-modulated arrays (TMAs) and frequency-diverse arrays (FDAs). The exploitation of innovative layouts allows to further improve these arrays performance thus avoiding the illumination of unwanted targets.
In both the near- and far-field applications, recent and innovative case studies will be discussed for the explanation of the theoretical aspects. Detailed description of the rectification nonlinear phenomenon will be given, together with strategies for the choice of the optimum rectifying receiving section layout depending on the application.

In the near-filed case the inductive and capacitive coupling mechanisms will be analysed, typical topologies of both are considered. The design rules for optimizing the overall efficiency will be applied to a case study consisting of the integrated design of the transmitter and receiver subsystems of an “on-the-move” WPT system.
