Optimized control system for Interoperable Wireless-Power Transfer systems for Light and Heavy-Duty Vehicles

Student thesis: Master's Thesis


Climate change, poor air quality in cities and the limited amount of fossil fuels have been a motivation for engineers to develop alternative transport technologies. Plug-In Hybrid electric vehicles (PHEVs) and battery electric vehicles (EVs) offer a good alternative for internal combustion engine (ICE) driven vehicles. These EVs are characterized by the presence of a large energy storage in the shape of a battery pack. To improve performances of EVs, charging methodologies need to be investigated. Wireless power transfer (WPT) chargers offer multiple advantages relative to other charging methods, and could even if applied on large scale, enhance performance of EVs by reducing battery dimensions or increase battery lifetime. This is why WPT and their applicability to EVs is treated in this thesis.
This thesis has presented a thoroughly state of art analysis of the existing topologies that could be used in WPT systems for light duty vehicles (LDVs) and heavy duty vehicles (HDV).
In this thesis, different new charging topologies are presented. The optimized topologies with respect to their control systems are designed and modeled. There are four topologies that have been developed for LDVs and HDVs. These topologies differ in the presence of an onboard DC-DC converter. The design and control systems of all topologies are made and modeled using MATLAB/ Simulink. The detailed control system of each subsystem has been described and verified in this thesis.
