Aarninkhof, Bram Oude (author), Lyu, Dingsihao (author), Soeiro, Thiago B. (author), Bauer, P. (author)In this article, a reconfigurable two-stage dc/dc resonant topology with a wide output voltage range of 150-1000 V is proposed for electric vehicle (EV) charging with high efficiency over the entire load range. The proposed topology consists of an LLC resonant converter with dual secondary sides; two interleaved triangular current mode (TCM)...journal article 2023

Liao, Jianquan (author), Zhou, Niancheng (author), Qin, Z. (author), Wang, Qianggang (author), Bauer, P. (author)The unbalanced power between positive and negative poles in a bipolar DC distribution network (DC-DN) generates an unbalanced current at the neutral line, which enlarges the power losses of the system and the voltage deviation of DC loads. An unbalanced power suppression strategy based on a series-parallel power flow controller (SP-PFC) is...journal article 2023

Xiao, J. (author), Wang, L. (author), Bauer, P. (author), Qin, Z. (author)Due to the mismatched feeder impedances in a resistive feeder AC microgrid, it's challenging to accurately share harmonic and active power while promising a low bus voltage distortion rate. To address this issue, this paper proposes a distributed philosophy-based virtual impedance modulation strategy. The proposed method regulates the...journal article 2023

Grazian, F. (author), Soeiro, Thiago B. (author), Bauer, P. (author)The lithium-ion battery of an electric vehicle (EV) is typically rated at either 400 or 800 V. When considering public parking infrastructures, EV wireless chargers must efficiently deliver electric power to both battery options. This can be normally achieved by regulating the output voltage through a dc-dc converter at the cost of higher...journal article 2023

Diab, I. (author), Eggermont, Rik (author), Chandra Mouli, G.R. (author), Bauer, P. (author)The decarbonization of urban bus fleets can be made by their electrification as in-motion-charging (IMC) buses which can run as trolleybuses or in battery mode. The benefit is that IMC buses can use the existing trolleygrid infrastructure where their route overlaps with it to charge the battery and operate in battery mode outside of it....journal article 2023

(author), van der Sar, T. (author)Quantum sensing has developed into a main branch of quantum science and technology. It aims at measuring physical quantities with high resolution, sensitivity, and dynamic range. Electron spins in diamond are powerful magnetic field sensors, but their sensitivity in the microwave regime is limited to a narrow band around their resonance...journal article 2023

Wang, Yi (author), Yang, Zhongping (author), Lin, Fei (author), Dong, J. (author), Bauer, P. (author)Compensation capacitors are naturally susceptible to manufacturing defects and aging effects, leading to the degraded performance of a wireless power transfer (WPT) system. This article focuses on the compensation parameters optimization during the design stage and control strategy during the operation phase to improve the inherent capacitor...journal article 2023

Bauer, Marlinda (author)Due to climate change, the growth in renewable energy is still accelerating and reaching new records each year. Not everything can be electrified, hence, the production of green hydrogen as an energy vector is gaining momentum. However, lowest cost hydrogen will not always be produced at the demand centres, necessitating transport of hydrogen...master thesis 2022

Bauer, Yorrick (author)A loss of vacuum accident in the hyperloop tunnel will likely occur during its operation, and it may have a severe impact on its operational safety. Nevertheless, the hyperloop tube breach has only been researched superficially.<br/><br/>Two aerodynamic phenomena due to the breach are identified: a (quasi-)steady underexpanded jet and an...master thesis 2022

Vermeer, W.W.M. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)Battery aging is one of the critical problems to be tackled in battery research, as it limits the power and energy capacity during the battery's life. Therefore, optimizing the design of battery systems requires a good understanding of aging behavior. Due to their simplicity, empirical and semiempirical models (EMs) are frequently used in...journal article 2022

Rituraj, G. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)In recent years, the research interest in off-grid (standalone mode) and hybrid (capable of both standalone and grid-connected modes) charging systems for electric vehicles (EVs) has increased. The main reason is to provide a seamless charging infrastructure in urban and rural areas where the electrical grid is unreliable or unavailable so that...journal article 2022

Bauer, M.S. (author)How does an organism regulate its genes? The involved regulation typically occurs in terms of a signal processing chain: an externally applied stimulus or a maternally supplied transcription factor leads to the expression of some downstream genes, which, in turn, are transcription factors for further genes. Especially during development, these...review 2022

Discovering those with valuable properties, however, too often relies on serendipity, because thermodynamic alloy design rules alone often fail in high-dimensional composition...journal article 2022

Kounalakis, M. (author), Bauer, G.E. (author), Blanter, Y.M. (author)We propose to directly and quantum-coherently couple a superconducting transmon qubit to magnons - the quanta of the collective spin excitations, in a nearby magnetic particle. The magnet's stray field couples to the qubit via a superconducting quantum interference device. We predict a resonant magnon-qubit exchange and a nonlinear radiation...journal article 2022
