A Computationally Efficient Quasi-Centralized DMPC for Back-to-Back Converter PMSG Wind Turbine Systems Without DC-Link Tracking Errors
(2016)
Quasi-centralized direct model predictive control (QC-DMPC) scheme may serve as an effective alternative for back-to-back power converter in permanent magnet synchronous generator (PMSG) wind turbine systems. However, model ...

This present paper has made with the objective of knowing the importance of HVDC interconnections, considering this systems has various configurations wich depend of projects being executed, for example the particular ...
Disappearance of squeezed back-to-back correlations: a new signal of hadron freeze-out from a supercooled quark gluon plasma
(Sociedade Brasileira de Física, 2007-09-01)
We briefly discuss four different possible types of transitions from quark to hadronic matter and their characteristic signatures in terms of correlations. We also highlight the effects arising from mass modification of ...
Back-to-back correlations in finite expanding systems
(American Institute of Physics (AIP), 2006-04-11)
Back-to-Back Correlations (BBC) of particle-antiparticle pairs are predicted to appear if hot and dense hadronic matter is formed in high energy nucleus-nucleus collisions. The BBC are related to in-medium mass-modification ...

PI tuning parameters in back-to-back converters applying active damping control for DC-voltage power port regulation
(Institute of Electrical and Electronics Engineers Inc., 2017-07-01)
In Back-to-Back converters, the controlled DC-voltage power port is employed as an integral part of the HVDC systems, variable-speed wind-power units, power electronics transformers (PETs) and other applications. The high ...
