Electronic Engineering Final
Year Project

Initial Presentation

Title:

Electromagnetic shielding techniques for inductive powering
applications



Supervisor :
Maeve Duffy



Project Overview


Investigating inductive power transfer in
two applications.



IPT allows the transfer of electrical power
without physical contact as a magnetic field
links energy directly to where it is required.



2 applications



Inductive charging platform


Used for charging different mobile electronic
devices, in which transmitter and receiver coils are
close together.



Implanted biomedical devices

(transmitter and receiver coils far apart and therefore
coupling levels are low)

Aim Of Project


The main aim of the project is to apply
modelling techniques to compare the
performance of different shielding layers
for both applications


and to develop effective shielding
solutions for the two applications.



Project Milestones:


Review of inductive powering technology and
applications


Transmitter and receiver circuits


Coil circuit models


EMI field limits for consumer and implanted biomedical devices





Program analytic formulas for electromagnetic fields
around planar windings in air


Matlab programming


FEA modelling (Ansoft) to compare with analytic solutions


Summary


This project will require a deep understanding of
different shielding techniques for inductive
powering applications using
analytic and FEA
modelling methods.



It will greatly improve my Knowledge of MATLAB
and SPICE.
