Nonlinear control of electronic converters: Fast and optimal control using sampling-driven nonlinear MPC

This thesis considers the design of the sampling-driven nonlinear model predictive controller (SD-NMPC) for power electronic converters. Most MPC schemes that are used nowadays lack in the application for systems with high sampling frequencies because of their high computational time, especially when the system is nonlinear. This is, for example...

Wireless Charging System for the Wireless Powerlizer

Wireless power transfer has been around for a long time. In 1899 Nikola Tesla demonstrated that it was possible to transfer power using a pair of coils. This technology has advanced to now charge a wide range of portable devices, such as phones. In this thesis, a wireless charging system is designed to be integrated into a power bank with UV-C...

Design of an 11kW DC-DC Resonant Converter for EV Charging with a 150-1000V Output Voltage Range

The worldwide adoption of Electric Vehicles (EV) has gained momentum in recent years, with more than 30% of all EVs being sold last year. Additionally, a new trend of 800 V battery architectures has appeared to allow for faster charging than the now common 400 V architectures. Future proof charging topologies should, therefore, be able to...
