A new control strategy for Neutral-Point-Clamped active rectifiers
No full textA new control strategy has been developed for interfacing a neutral-point-clamped active rectifier with the mains. In particular, a method, based on the modulation of the input currents amplitudes, is proposed to compensate the dc-link capacitors voltages fluctuations. The proposed strategy gives good results in all the operating conditions, but it appears to be very useful especially in no-load or low-load operations, where other methods fail. Analytical, simulation, and experimental results, derived from a reduced-scale prototype, are presented and confirm the validity of the proposed approach

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
