Study of the influence of Er/Ln co-doping in La2O3 thin films on their up-conversion properties (where Ln ¼ Ho or Nd)
(Elsevier, 2020)
In this study we report significant enhancement of up-conversion emissions of La2O3:Er thin films when they are co-doped with Er/Ln (where Ln = Nd or Ho). The proposed mechanisms by which the Ln ions contribute to these ...
A COMPARATIVE STUDY OF MPPT STRATEGIES AND A NOVEL SINGLE-PHASE INTEGRATED BUCK-BOOST INVERTER FOR SMALL WIND ENERGY CONVERSION SYSTEMS
(Ieee, 2011-01-01)
This paper presents the analysis of some usual MPPT (Maximum Power Point Tracking) strategies intended for small wind energy conversion (up to 1kW) based on permanent magnet synchronous generators (PMSG), considering the ...
