Samenvatting
This thesis titled ”Wireless Power Transfer System for Electric Vehicles: Design, Modeling and Interoperability Analysis” is submitted by Julien Kestemont in order to be awarded the master’s degree in Industrial Engineering Electromechanics with specialization in Trans- port Technology, for the academic period 2017-2018.Wireless Power Transfer (WPT) systems are continuously under development in various field. In this case, the presented study focuses on the automotive world for the recharge of the electric vehicles batter- ies. In a WPT system, the design approach and the implemented control strategies will have an impact on the charging power, charging time, possible misalignment and the efficiency.
In the first stage, this thesis investigates the analysis of a High Power Level (22 kW) Series-Series (S-S) WPT system prototype operating at a frequency of 21 kHz. This analysis consists of an ideal system simulation, a loss analysis including a resonant switching loss approach and the integration of the Series- Parallel-Parallel-Series (SP-PS) compensation topology approach. These simulations and approaches are done and verified by using Matlab/Simulink.
Secondly, a Low (3,7 kW) and Medium (7,7 kW) Power Level S-S WPT systems are analyzed for the investigation of a possible interoperability between the Low, Medium and High Power Levels including a mutual inductance analysis.
Finally, a misalignment analysis is effectuated with self made primary and secondary DD-coils and simulated with the 22 kW WPT system hardware to compare the power transfer with basic rectangular coils.
