MHz Wireless Power: Topologies, Magnetics, Safety and Synchronisation

Paul
Pr. Paul D. Mitcheson

Professor at Electrical and Electronic Engineering Department, Imperial College London, U.K.

Abstract: MHz wireless power can provide an alternative to kHz solutions and in some applications can lead to lighter weight solutions and greater misalignment tolerances. In this talk I will cover the basics of MHz wireless power, including circuit topologies, and then move on to look at some of the prerequisites for making it work in a real world environment, including safety and synchronisation for active rectification. I will also cover some applications that the Imperial spinout, Bumblebee Power, is targeting.

Introduction to Electromagnetic Compatibility and Electromagnetic Field Safety Aspects in Near Field Wireless Power Transfer Systems

Pr. Mauro Feliziani

Professor or Electrical Engineering, University of L’Aquila, Italy

Abstract: The aim of the talk is to present the main aspects of electromagnetic compatibility (EMC) and electromagnetic field (EMF) safety of near-field wireless power transfer systems. The basic principles of EMC and EMF safety will be briefly explained. WPT systems used for wireless battery charging are intentional sources of time-varying magnetic fields that can be very large for high-power WPT applications. A major concern is therefore the compliance of magnetic fields with EMC and EMF safety standards and regulations. Traditional mitigation techniques such as shielding cannot be applied without degrading the performance of the WPT. The characterization of the magnetic field in critical applications such as automotive is presented. Innovative mitigation techniques are then illustrated. Some examples of typical EMC and EMF safety problems are provided in terms of conducted and radiated emissions and dosimetric analysis, respectively.

Smart radiating architectures for energy-aware wireless power transfer

Masotti
Dr. Diego Masotti

Associate Professor University of Bologna, Italy

Abstract: In wireless power transfer (WPT) applications the weakest contribution to the overall link efficiency is the effective selection of the zone to be powered. Hence, the need for smart transmitting architectures is strong. In this talk, two promising families of highly-reconfigurable arrays are presented: first, time-modulated arrays (TMAs) are considered as a powerful tool for selective WPT, through their peculiar sideband radiation phenomenon; frequency-diverse arrays (FDAs) are, then, proposed as a smarter solution, able to focus the beam in range, too, thus avoiding the illumination of unwanted targets.
