1. Final Year Project Project Progress Presentation Title: Development of electrical models for inductive coils used in wireless power systems Paul Burke Electronic and Computer Engineering Supervisor: Dr. Maeve Duffy

2. Aim of Project The main aim of the project is to develop Matlab programs to predict the inductance, AC resistance and magnetic field levels of coils used in wireless charging systems. Testing on prototype coils in the lab to prove results Simulation using Finite Element Analysis(i.e Ansys Maxwell)

3. Progress to Date Develop a Matlab program to calculate the inductance of a coil. Allows user to enter coil specification Based on these specifications in calculates inner and outer radii

4. Progress to Date Integrates the equation in function file(FNF1) to infinity Uses this value to calculate inductance(L)

5. Progress to Date Develop a Matlab program to calculate the resistance and inductance of a coil Allow user to enter coil spec Resistance Equation Divide coil into number of sections Cross Section of coil

6. Project Plan January – Complete Matlab program to calculate resistance and inductance of coil. Verify results using finite element analysis software. Test prototype coils in Lab February – Create efficient Matlab code to calculate H-field around coils March – Review code to make more efficient and write final report
