Kardan Halvaei, F. (author), Shekhar, A. (author), Bauer, P. (author)EV fast chargers are essential in addressing the concern of limited driving range for E-mobility applications. However, the load profile of a converter for fast charging involves a high-current pulse that can last for a few minutes to efficiently replenish the EV battery, which is followed by a cooldown period after the charging process is...conference paper 2023

Zhu, G. (author), Dong, J. (author), Bauer, P. (author)It is ideal for the wireless power transfer (WPT) systems to operate at the resonance state for better transmission performance. In practice, however, the parameters of the resonant circuits often deviate because of the capacitance drift and coil misalignment. To this end, this paper proposes a new parameter estimation method for the WPT systems...conference paper 2023

Deshmukh, R.S. (author), Rituraj, G. (author), Lock, Niels (author), Vahedi, H (author), Shekhar, A. (author), Bauer, P. (author)Power electronics converters (PEC) play a crucial role in interfacing renewable energy systems and electrolyzers to ensure a high production yield of green hydrogen. The design of such PEC is not straightforward due to the safety hazards of using multiple electrolyzer stacks and converter modules at industrial levels. Therefore, real-time...conference paper 2023

Deshmukh, R.S. (author), Rituraj, G. (author), Vahedi, H (author), Shekhar, A. (author), Bauer, P. (author)Electrolysis requires a high DC current at low voltage to produce hydrogen from water. Designing power converters for such a load requirement could be challenging while fulfilling the galvanic isolation needs. Therefore, prior knowledge of the electrolyzer's impact on the converter operation should be needed. In this context, this paper...conference paper 2023

Molenaar, M. (author), Kardan Halvaei, F. (author), Shekhar, A. (author), Bauer, P. (author)The reliability of semiconductor power devices can be studied by performing a thermal and power cycling test. In order to create the desired temperature cycles, there are four free variables to select during the power cycling test, namely the heating current, heating time, cooling time, and heatsink temperature. In this paper, the relation...conference paper 2023

(author)Two-stage AC-DC converters are considered as a prominent solution for DC-type electric vehicle (EV) chargers. However, this kind of architecture suffers from high switching losses with large heatsink and DC-link capacitor volume. To relieve this issue, this paper presents a new hybrid modulation for DC-type EV chargers, where a two-phase...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
