Yang, Y. (author), Huang, Mo (author), Du, S. (author), Martins, Rui P. (author), Lu, Yan (author)High-frequency buck converters need a fast transition of switching nodes (high dv/dt). Such high dv/dt, especially the positive one, can cause malfunction of a conventional pulse-triggered active-coupled (PTAC) level shifter that is used to control the high-side NMOS switch. In this work, we first discuss the dv/dt immunity of conventional PTAC...journal article 2023

Ye, Guigen (author), Fan, X. (author), Middelburg, L.M. (author), el Mansouri, B. (author), Poelma, René H. (author), Zhang, Kouchi (author)In this paper, stability and mechanistic simulations for a four-beam-mass-based MEMS gravimeter were conducted, and guidelines for the gravimeter design were proposed. Based on a prototyped MEMS device, the nonlinear finite element model was validated first against the experimental results. Then, we demonstrated three different scenarios in...journal article 2022

Oude Aarninkhof, Bram (author)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...master thesis 2021

Hurkmans, Brecht (author), van der Kolk, Floris (author)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...bachelor thesis 2021

Koch, Rik (author)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...master thesis 2021

Urso, A. (author), Giagka, Vasiliki (author), van Dongen, M.N. (author), Serdijn, W.A. (author)In order to recruit neurons in excitable tissue, constant current neural stimulators are commonly used. Recently, ultra high-frequency (UHF) stimulation has been proposed and proven to have the same efficacy as constant-current stimulation. UHF stimulation uses a fundamentally different way of activating the tissue: each stimulation phase is...journal article 2019
