Lyu, D. (author), Straathof, C.A. (author), Soeiro, Thiago B. (author), Qin, Z. (author), Bauer, P. (author)This paper proposes two modulation schemes for Dual Active Bridge (DAB) converters, with the aim of maximizing Zero Voltage Switching (ZVS) operation over a wide operational range. The first is a ZVS-optimized constant frequency modulation scheme, constructed based on the boundary conditions of ZVS operation. This scheme maximizes the number...journal article 2023

Lyu, D. (author), Straathof, C.A. (author), Soeiro, Thiago B. (author), Qin, Z. (author), Bauer, P. (author)A variable switching frequency modulation for the Dual Active Bridge (DAB) converter is proposed in this paper. With this variable switching frequency modulation, the DAB converter can be operated in the ZVS-beneficial operational modes without the necessity to transition to others, thus a larger ZVS range for the DAB converter can be...conference paper 2023

(author)The past few years have seen strong growth of solar-based off-grid energy solutions such as Solar Home Systems (SHS) as a means to ameliorate the grave problem of energy poverty. Battery storage is an essential component of SHS. An accurate battery model can play a vital role in SHS design. Knowing the dynamic behaviour of the battery is...journal article 2018

Shekhar, A. (author), Prasanth, V. (author), Bauer, P. (author), Bolech, M. (author)The economic viability of on-road wireless charging of electric vehicles (EVs) strongly depends on the choice of the inductive power transfer (IPT) system configuration (static or dynamic charging), charging power level and the percentage of road coverage of dynamic charging. In this paper, a case study is carried out to determine the expected...journal article 2016

Fragoso Rodrigues, S.M. (author), Bauer, P. (author), Bosman, P.A.N. (author), Pierik, J. (author)Offshore wind farms with high installed capacities and located further from the shore are starting to be built by northern European countries. Furthermore, it is expected that by 2020, several dozens of large offshore wind farms will be built in the Baltic, Irish and North seas. These wind farms will be constituted of a considerable number of...conference paper 2014

Rodrigues, S. (author), Bauer, P. (author), Pierik, J. (author)Although, only in recent years, northern European countries started to install large offshore wind farms, it is expected that by 2020, several dozens of far and large offshore wind farms (FLOWFs) will be built. These FLOWFs will be constituted of a considerable amount of wind turbines (WTs) packed together, leading to an energy density increase....conference paper 2013

Teixeira Pinto, R. (author), Fragoso Rodrigues, S. (author), Wiggelinkhuizen, E. (author), Scherrer, R. (author), Bauer, P. (author), Pierik, P. (author)For achieving the European renewable electricity targets, a significant contribution is foreseen to come from offshore wind energy. Considering the large scale of the future planned offshore wind farms and the increasing distances to shore, grid integration through a transnational DC network is desirable for several reasons. This article...journal article 2012

Van der Pijl, F.F.A. (author), Ferreira, J.A. (author), Bauer, P. (author), Castilla, M. (author)The invention relates to an adaptive controlling method for controlling energy- supplied by an electrical source (14) to a resonance tank (Cr, Lr) that is connectable to an electric load (13a, 13b). The method comprises the step of determining an energy amount to be supplied to the tank (Cr, Lr), based on information of energy in the resonance...patent 2011

(author)EeFarm-II is used to evaluate 13 different electrical systems for a 200 MW wind farm with a 100 km connection to shore. The evaluation is based on component manufacturer data of 2009. AC systems are compared to systems with DC connections inside the wind farm and DC connection to shore. Two options have the best performance for this wind farm...journal article 2010

Baalbergen, F. (author), Bauer, P. (author), Ferreira, J.A. (author)Diesel generators in small electricity grids are mostly not used in a very efficient way. The reason for this is twofold. First of all, the efficiency of a diesel generator is dependent on the ratio determined by the average power divided by the peak power of the generator. The smaller this ratio is, the lower the efficiency. Furthermore, some...journal article 2009

(author)In this work self-organized SiGe islands are used as stressors for Si capping layers, which later act as carrier channels in field effect transistors. To be able to address individual islands and to obtain a sufficiently narrow distribution of their properties, the SiGe islands are grown by molecular beam epitaxy on prepatterned Si substrates,...journal article 2009

Zhou, Y. (author), Bauer, P. (author), Ferreira, J.A. (author), Pierik, J. (author)Doubly fed induction generator (DFIG) still shares a large part in today's wind power market. It provides the benefits of variable speed operation cost-effectively, and can control its active and reactive power independently. Crowbar protection is often adopted to protect the rotor-side voltage source converter (VSC) from transient overcurrent...journal article 2009
