Abstract of doctoral thesis - Korakianitis Nikolaos

"Wireless charging and discharging of electric vehicles and optimization of their integration in Smart Grids"

Τhe subject of the PhD is multidisciplinary and belongs to the area of Power Electronics, Electromagnetism and Smart Grids. In the proposed PhD thesis,thatdeals with the IPTS (Inductive Power Transfer System)of electromotive vehicles and the purpose is the theoretical analysis of the wireless inductive charging system via the mathematical systemanalysisand the physical systemdesign and installationin an outdoors environment and its interconnection with smart grids. The main issue is the analysis of the problems that hinder it and the problems that it creates due to its particular electromagnetic nature. Consequently, the thesis reviews international research and the provisions that have been created so far, as well as the innovations in the solutions to problems faced by inductive wireless charging systems.
More specifically, the thesis is divided into two parts. The first partwill be the mathematical part of the thesis and shows how an wireless inductive charging system that is essentially a transformer, can work without a core and how the valuesof transformers parametersbe affected during its operation and the correction done by the system inverter.Finally, a software simulation is presented that shows how a DC voltage can eventually feed a battery of an electromotive vehicle.
The second part of the thesis deals with the physical system, the installation of a wireless inductive charging system with an inverter and its strong electromagnetic interference (EMI). Considering that the system is mostly intended for outdoor use, the IP (International Protection Marking) standards are presented, thus giving solutions through it in order to preserve immunity to nature's elements and at the same time maintaining immunity to the electromagnetic radiation produced by the transformer and internal elements of the inverter. This sectiondeals the designing of the housing for the inverter, the cooling system and choosing the cooling method as well as magnetically shielding all the components of the system.
Finally, the magnetic field modulus methodology is described, that significantly increases the efficiency of the wireless inductive charging system, allowing for easier shielding and safer usage of the transformer. Furthermore, the wireless inductive charging system interconnection with the smart grids is examinedand presented.
