De Jong, E.C.W. (author), Ferreira, B.J.A. (author), Bauer, P. (author)A means for power electronics to exploit the level of 3-D packaging already being implemented in compact consumer products, such as digital cameras, is investigated in order to increase its power density. The increase in functionality and usage of printed circuit board (PCB) in power electronic converters is highlighted and improvements proposed...journal article 2008

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

Coupling of a CMOS Optical Sensor to a Micromachined Deformable Mirror with an Adaline Neural MethodDe Lima Monteiro, D.W. (author), Ferreira, A.I. (author), Teixeira, F.B. (author), Melo, J.G.M. (author), Vdovin, G.V. (author)We report on the preliminary results of an Adaline neural method for the coupling of a custom CMOS wavefront sensor to a micromachined adaptive mirror. The algorithm does not rely on a fixed basis matrix -as opposed to traditional methods-, offers excellent immunity to round-off errors and admits real-time input adaptability to speed up...journal article 2006

Zhao, D. (author), Ferreira, J.A. (author), Roc'h, A. (author), Leferink, F. (author)Filters used in electromagnetic interference suppression are often described in literature on drive systems and have become a standard solution in industry. The effect of the commercial off-the-shelf filter depends significantly on how it is installed. A model that includes the installation parameters is made first and then the parameters of the...journal article 2009

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)A strategy for spectroscopy tissue diagnosis using a small number of wavelengths is reported. The feasibility to accurately quantify tissue information using only 16 wavelengths is demonstrated with several wavelength reduction simulations of the existing esophageal data set. These results are an important step for the development of a...journal article 2011
